Python Programming Language
Python Programming Language
Python is one of the most loved programming languages by developers, data scientists, software engineers, and even hackers because of its versatility, flexibility, and object-oriented features.
- High Level Language
- Can do complex tasks
- Easy to Learn
- Productive coding environment
- Open source web application
- Used to create web applications
- Runs on an interpreter system
Python Variables
Variables are used to store value in it.
Example:-
x = 5
print(x)
Output:-
5
Rules for python variables:-
- Variable name must start with a alphabet or underscore.
- It can not start with a number.
- They are case sensitive.
- They should not contain any special character.
Example:- my_var, hello_world, _myname
Python Comments
Comments in python starts with #. Comments can be used to make more readable. Comment line can be placed anywhere in the program.
Example :-
#This is Passable Blog.
print('Passable Blog')
Output:-
Passable Blog
Python Operators
Arithmetic Operators
+ Addition (x + y)- Subtraction (x - y)* Multiplication (x * y)/ Division (x/ y)% Modulus (x % y)** Exponentiation (x ** y)// Floor division (x // y)
Comparison operators
== Equal (x == y)!= Not equal (x != y)> Greater than (x > y)< Less than (x < y)>= Greater than or equal to (x >= y)<= Less than or equal to (x <= y
Logical operators
and Returns True if both statements are trueor Returns True if one of the statements is truenot Reverse the result, returns False if the result is true
Python Built-in functions
all() - It returns True if all items in a list are true.

myblog = [True, False, False]
p = any(mynlog)
print(p)
Output:-
True
bin() - It returns the binary value of a number.
Example:-
p = bin(3)
Output:-
0b011
chr() - It returns a character from the specified Unicode code.
Example:-
p = chr(97)
print(p)
Output:-
a
complex() - It returns a complex number.
Example:-
p = complex(5, 2)
print(p)
Output:-
5+2j
divmod() - It returns the quotient and the remainder .
Example:-
p = divmod(5, 2)
print(p)
Output:-
(2, 1)
float() - It returns a floating point number.
Example:-
p = float(5)
print(p)
Output:-
5.0
hex() - It converts a number into a hexadecimal value.
Example:-
p = hex(255)
print(p)
Output:-
0xff
input() - It allows user to input.
Example:-
a = input('Enter your name : ')
print(a)
Output:-
Enter your name : Ashita
Ashita
int() - It return integer number.
Example:-
p = int(5.3)
print(p)
Output:-
5
len() - It returns the length of the item.
Example:-
a = ashita
n = len(a)
print(n)
Output:-
6
max() - It returns the largest item in a list.
min() - It returns the smallest item in a list.
oct() - It converts a number into an octal value.
Example:-
p = oct(12) print(p)
Output:-
0o14
pow() - It returns the value of p to the power of q.
Example:-
p = pow(2, 4)
print(p)
Output:-
16
print() - It prints the output.
Example:-
print('This is Passable Blog.')
Output:-
This is Passable Blog.
round() - It rounds up a number upto the given decimal numbers.
Example:-
a = 2.45346
a = round(a,2)
print(a)
Output:-
2.45
str() - It returns a string.
Example:-
