Variables

Python supports different type of variables such as whole numbers, floating point numbers and text.  You do not need to specify the type of variable, you can simply assign any value to a variable. Type the program below and start it.

#!/usr/bin/python
 
x = 3              # a whole number                   
f = 3.1415926      # a floating point number              
name = "Python"    # a string
 
print(x)
print(f)
print(name)

combination = name + " " + name
print(combination)

sum = f + f
print(sum)
