Operators in Python

Operators are some special symbols with the help of these symbols we perform logical and arithmetic operations.

On which variables operation are performed are called operands

example :-

# (+) is operator and, a and b are operands on which operation are perform
a = 5
b = 4
c = a + b
print(c)

Python

Following are some common operators in python are:-

1 – Arithmetic Operator

Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication, etc.

Operator	Meaning	Example
+	Add two operands or unary plus	x + y+ 2
–	Subtract right operand from the left or unary minus	x – y- 2
*	Multiply two operands	x * y
/	Divide left operand by the right one (always results into float)	x / y
%	Modulus – remainder of the division of left operand by the right	x % y (remainder of x/y)
//	Floor division – division that results into whole number adjusted to the left in the number line	x // y
**	Exponent – left operand raised to the power of right	x**y (x to the power y)

Example 1: Arithmetic operators in Python

x = 15
y = 4

# Output: x + y = 19
print('x + y =',x+y)

# Output: x - y = 11
print('x - y =',x-y)

# Output: x * y = 60
print('x * y =',x*y)

# Output: x / y = 3.75
print('x / y =',x/y)

# Output: x // y = 3
print('x // y =',x//y)

# Output: x ** y = 50625
print('x ** y =',x**y)

Markup

Output :-

x + y = 19

x - y = 11

x * y = 60

x / y = 3.75

x // y = 3

x ** y = 50625

Markup

Comparison operators

Comparison operators are used to compare values. It returns either True or False according to the condition.

Operator	Meaning	Example
>	Greater than – True if left operand is greater than the right	x > y
<	Less than – True if left operand is less than the right	x < y
==	Equal to – True if both operands are equal	x == y
!=	Not equal to – True if operands are not equal	x != y
>=	Greater than or equal to – True if left operand is greater than or equal to the right	x >= y
<=	Less than or equal to – True if left operand is less than or equal to the right	x <= y

Example 2: Comparison operators in Python

x = 10
y = 12

# Output: x > y is False
print('x > y is',x>y)

# Output: x < y is True
print('x < y is',x<y)

# Output: x == y is False
print('x == y is',x==y)

# Output: x != y is True
print('x != y is',x!=y)

# Output: x >= y is False
print('x >= y is',x>=y)

# Output: x <= y is True
print('x <= y is',x<=y)

Python

Output

x > y is False

x < y is True

x == y is False

x != y is True

x >= y is False

x <= y is True

Markup

Logical operators are the and, or, not operators.

Operator	Meaning	Example
and	True if both the operands are true	x and y
or	True if either of the operands is true	x or y
not	True if operand is false (complements the operand)	not x

Example 3: Logical Operators in Python

x = True
y = False

print('x and y is',x and y)

print('x or y is',x or y)

print('not x is',not x)

Python

Output :-

x and y is False
x or y is True
not x is False

Markup

Here is the truth table for these operators.

---

Bitwise operators

Bitwise operators act on operands as if they were strings of binary digits. They operate bit by bit, hence the name.

For example, 2 is 10 in binary and 7 is 111.

In the table below: Let x = 10 (0000 1010 in binary) and y = 4 (0000 0100 in binary)

Operator	Meaning	Example
&	Bitwise AND	x & y = 0 (0000 0000)
|	Bitwise OR	x | y = 14 (0000 1110)
~	Bitwise NOT	~x = -11 (1111 0101)
^	Bitwise XOR	x ^ y = 14 (0000 1110)
>>	Bitwise right shift	x >> 2 = 2 (0000 0010)
<<	Bitwise left shift	x << 2 = 40 (0010 1000)

---

Assignment operators

Assignment operators are used in Python to assign values to variables.

a = 5 is a simple assignment operator that assigns the value 5 on the right to the variable a on the left.

There are various compound operators in Python like a += 5 that adds to the variable and later assigns the same. It is equivalent to a = a + 5.

Operator	Example	Equivalent to
=	x = 5	x = 5
+=	x += 5	x = x + 5
-=	x -= 5	x = x – 5
*=	x *= 5	x = x * 5
/=	x /= 5	x = x / 5
%=	x %= 5	x = x % 5
//=	x //= 5	x = x // 5
**=	x **= 5	x = x ** 5
&=	x &= 5	x = x & 5
|=	x |= 5	x = x | 5
^=	x ^= 5	x = x ^ 5
>>=	x >>= 5	x = x >> 5
<<=	x <<= 5	x = x << 5

---

Special operators

Python language offers some special types of operators like the identity operator or the membership operator. They are described below with examples.

Identity operators

is and is not are the identity operators in Python. They are used to check if two values (or variables) are located on the same part of the memory. Two variables that are equal does not imply that they are identical.

Operator	Meaning	Example
is	True if the operands are identical (refer to the same object)	x is True
is not	True if the operands are not identical (do not refer to the same object)	x is not True

Example 4: Identity operators in Python

x1 = 5
y1 = 5
x2 = 'Hello'
y2 = 'Hello'
x3 = [1,2,3]
y3 = [1,2,3]

# Output: False
print(x1 is not y1)

# Output: True
print(x2 is y2)

# Output: False
print(x3 is y3)

Python

Output

False
True
False

Markup

Here, we see that x1 and y1 are integers of the same values, so they are equal as well as identical. Same is the case with x2 and y2 (strings).

But x3 and y3 are lists. They are equal but not identical. It is because the interpreter locates them separately in memory although they are equal.

---

Membership operators

in and not in are the membership operators in Python. They are used to test whether a value or variable is found in a sequence (string, list, tuple, set and dictionary).

In a dictionary we can only test for presence of key, not the value.

Operator	Meaning	Example
in	True if value/variable is found in the sequence	5 in x
not in	True if value/variable is not found in the sequence	5 not in x

Example #5: Membership operators in Python

x = 'Hello world'
y = {1:'a',2:'b'}

# Output: True
print('H' in x)

# Output: True
print('hello' not in x)

# Output: True
print(1 in y)

# Output: False
print('a' in y)

Python

Output

True
True
True
False

Markup

Here, 'H' is in x but 'hello' is not present in x (remember, Python is case sensitive). Similarly, 1 is key and 'a' is the value in dictionary y. Hence, 'a' in y returns False.

I hope you understand the concept of operators in python. If you have any query or suggestion please do a commnet.

Thank You.

Variables and Data types in Python

What is variables ?

A variable is a name given to a memory location in a program.

Example : –

a = 5

b = "This is a string"

c = 4.5

Python

variable is use to contain a value.

What is keyword ?

Predefine or reversed words in programmming languages are called keywords.

ex – print(), input() etc all are keywords.

What is identifier ?

An identifier is nothing but a name assigned to an element in a program. Example, name of a variable, function, etc. Identifiers are the user-defined names . As the name says, identifiers are used to identify a particular element in a program.

Data Types in python

Data type identify the type of variable. Data type is an important concept. Variables can store data of different types, and different types can do different things.

 

Basic Data Types in Python :

1. Integer – a number without decimals ( 1, 55, 234 )
2. Float – a number with decimals values ( 2.4, 5.8 )
3. Strings – A set of characters called strings ( this is a string ) and strings are written inside the double or single quotes
4. Booleans :- True or False
5. None :- Doesn’t not contain any value.

Python is a fantastic programming language that automatically identifies the type of variables

Example :-

a = 71 ( identifies as <int>) means it is an integer value

b = 2.5 (identifies as <float> ) means it is a floating number.

c = “string” ( identifies as <str> ) means it is a string value

Type casting using Type() function.

Type() function is use to find the data type of a variable in python

example :-

a = 8

print(type(a))

b =7.3

print(type(b))

c = "string"

print(type(c))

Python

Output : –

<class 'int'>
<class 'float'>
<class 'str'>

Markup

Note : – Every thing in python is an object.

( Hello World !) Program and Comments in Python

Today we are going to write our first program in python. So let’s start. Open your code editor and start writing with me .

print("Hello World ! This is your first python program.")

Python

Output : –

Hello World ! This is your first python program.

Markup

Congratulations you write your first python program.

Let’s understand how its work. Print is a built in function when we want to display ouput on screen we use print function any thing inside the print its print on the output screen.

What is Comments in python ?

Any line of code that we dont want to execute with program and compiler ignore those lines are called comments.

Example:-

# This is a comment 
print(" We use hash (#) to comment. ")

Python

There are two types of comments

1. Single line comments : – Using # in above example
2. Multi line comment : – When we want to comment more than one line then we use multi line comment using (”’ ”’) triple quote symbol.

Example : –

# this is a single line comment

print("Hello world")

''' this 

        is 

          multi line comment '''

Python

I hope you learn and enjoy how to write program in python . If you have any query or suggestion please do a comment.

Thank You !

Introduction to Python

What is Python ?

Those who are coming from a coding background already know that python is a programming language or if you dont know dont worry i’m here to tell you about everything about python.

So, lets started. Python is an interpreted ( run line by line ), general-purpose ( use every where ) and high-level programming language ( easy readable and understandable ). It was created by Guido van Rossum during 1985 – 1990.

Why to learn python?

Python is very easy language to learn as compare to other programming language it is widely used. It supported all the funcationality of other programming lanuages like Object-oriented and functional programming and many more. It uses english keywords where as other languages use punctuation.

Advantages : –

1. Easy to learn, read and write
2. Its improved productivity you do not need to write more code you can simply write less and your work is done. Because every thing in python is already written you have to just import modules ( if you don’t understand import modules don’t worry we talk about later ) these code and use them very easily That’s why it also called write less and do more.
3. Dynamically typing its automatically know the type of variables you dont need to declare its type.
4. Free and open source, you can use python for free and its has very large community to support so you will never stuck at any point.
5. Portability once you write the code you can run at any platforms.
6. you can start your career in web development, mobile development,descktop development,machine learning,A.I, Data science and automation with the help of by learning its frameworks, library and modules.

Disadvantages : –

1. Slow speed as compare to any other programming languages like c,c++, java it quite slower than these langauges.
2. Weak in mobile computing
3. Database access
4. Runtime errors

Modules in Python

A module is a file containing code written by somebody (else usually ) which can be imported and used in our programs.

Types of modules:-

1. Builtin modules :- Those modules that are allready comes with python we do not need to import them. like ( os, apc ) etc.
2. External modules :- Those modules which are imported that are wriiten by some one else using PIP. Like ( flask, django, tenserflow , pandas, numpy ) etc.

What is pip ?

Pip is a package manager for python you can use pip to install a module in your program.

go to terminal or powershell and type but first python is install in your pc. To install python go to python.org download and simply intsall and after that run this command in your terminal or powershell.

pip install flask

Python

flask is a external module with the help of pip we install flask in our sytstem and use it later accordingly . basically it is use for developming web application or connecting to database ( like mysql ) etc.

REPL ( Read Evaluate print loop )

we can use python simple as a calculator

1. Go to terminal
2. Type python and press enter.
3. now you can do simple maths calculation like ( add muliply subtract divide)

for now its done here . we learn more about python later in this tutorial we seen python installation module if you dont understand dont worry when we do praticale then we understand better .

C - Basic Introduction

C is a general-purpose high level language that was originally developed by Dennis Ritchie for the Unix operating system. It was first implemented on the Digital Equipment Corporation PDP-11 computer in 1972.

The Unix operating system and virtually all Unix applications are written in the C language. C has now become a widely used professional language for various reasons.

• Easy to learn
• Structured language
• It produces efficient programs.
• It can handle low-level activities.
• It can be compiled on a variety of computers.

Facts about C

• C was invented to write an operating system called UNIX.
• C is a successor of B language which was introduced around 1970
• The language was formalized in 1988 by the American National Standard Institue (ANSI).
• By 1973 UNIX OS almost totally written in C.
• Today C is the most widely used System Programming Language.
• Most of the state of the art software have been implemented using C

Why to use C ?

C was initially used for system development work, in particular the programs that make-up the operating system. C was adoped as a system development language because it produces code that runs nearly as fast as code written in assembly language. Some examples of the use of C might be:

• Operating Systems
• Language Compilers
• Assemblers
• Text Editors
• Print Spoolers
• Network Drivers
• Modern Programs
• Data Bases
• Language Interpreters
• Utilities

Worth to know about C language

• Oracle is written in c
• Core libraries of android are written in c
• MySQL is written in c
• Almost every device drivers is written in c
• Major part of the browser is written in c
• Unix operating system is developed in c
• C is the world's most popular programming language

For students :-

• C is important to build programming skills
• C covers basic features of all programming language
• Campus recruitment process
• C is the most popular language for hardware dependent programming

C Program File

All the C programs are written into text files with extension ".c" for example hello.c. You can use "vi" editor to write your C program into a file.
This tutorial assumes that you know how to edit a text file and how to write programming instructions inside a program file.

C Compilers

When you write any program in C language then to run that program you need to compile that program using a C Compiler which converts your program into a language understandable by a computer. This is called machine language (i,e. binary format). So before proceeding, make sure you have C Compiler available at your computer. It comes along with all flavors of Unix and Linux.

If you are working over Unix or Linux then you can type gcc -v or cc -v and check the result. You can ask your system administrator or you can take help from anyone to identify an available C Compiler at your computer.

If you don't have C compiler installed at your computer then you can use below given link to download a GNU C Compiler and use it.
