Numeric variables example

Example of numeric variables:

x = 1

z = True

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

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

User input

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)
