Python variables

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

Numbers can be of one of these datatypes:

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)

Python 2 (old version)
You can also ask the user for input using the raw_input function:

#!/usr/bin/env python

x = int(raw_input("Enter x:"))
y = int(raw_input("Enter y:"))

sum = x + y
print(sum)
