Variables can hold numbers that you can use one or more times.

Numbers can be of one of these datatypes:

Numeric variables example

Example of numeric variables:

x = 1
y = 1.234
z = True

You can output them to the screen using the print() function.

x = 1
y = 1.234
z = True
 
print(x)
print(y)
print(z)

Python supports arithmetic operations like addition (+), multiplication (*), division (/) and subtractions (-).

#!/usr/bin/env python
 
x = 3
y = 8
 
sum = x + y
 
print(sum)

Python 3
Use the input() function to get text input, convert to a number using int() or float().

#!/usr/bin/env python
 
x = int(input("Enter x:"))
y = int(input("Enter y:"))
 
sum = x + y
print(sum)
