python
Basic of python
The python is the develop in the author: Guido van rossum in 1991
The python is interperters and compiler language
The python difference in interperters and compiler
interper:
It excutes a program line by line
It is a slow process
It does not generate any form of output
It takes less utilized of cpu
compiler:
It translates a program on a single run
It is fast process
It generate output in the form of .excuted
It is utilized cpu more

python divides the operators in the following groups
Types of operators
Arithmetic operators
Assignment operators
comparison operators
logical operators
bitwise operators
Membership operators

program

Arithmetic operators

The Arithmetic operators is numeric value is mathematical operators
1.Addition
2.Subtraction
3.Multlplication
4.Division
5.Modules
6.Floor division

Addition

a=3
b=2
print(a + b)
O/P
5

subtraction

a=6
b=5
print(a-b)
O/P
1

multplication

a=25
b=25
print(a*b)
O/P
500

division

a=12
b=3
print(a/b)
O/P
4

modules

a=5
b=2
print(a % b)
O/P
1

floor division

a=15
b=2
print(a//b)
O/P
7
2.Assignment operators
The assignment operators is a assign value to varables

Assign values=

a=4
print(a)
o/p

Assign values+=

x=2
x+=2
print(x)
o/p
4

Assign value-=

x=2
x-=2
print(x)
o/p

Assign value*=

x=6
x*=2
print(x)
o/p

Assign value/=

x=6
x/=3
print(x)
o/p

3.Comparsion operators
The Comparsion operatror is compare two values

equal ==

x=3
y=6
print(x==y)
false

not equal!=

x=3
y=6
print(x!=y)
o/p
True

greater equal>=

x=3
y=6
print(x>=y)
o/p
true

less equal<=

x=3
