Why doesn't my squaring function run?

Question

I decided to make a program that would square a number just for fun. Using an online compiler, I entered my code and from what I saw there were no errors; it wouldn\'t run it wo

Answer 1

Do make sure you also call your function:

def square():
    # your function body here

square()

But in your function, you are ignoring the result of your calculation here:

number*number

Assign that result to something:

answer = number * number
print "Your answer is..."  
print answer  

You don't have a number, however. raw_input() returns a string, so you want to convert that to a number first:

number = int(number)

This assumes that the user actually entered something that can be converted to an integer; digits only, plus perhaps some whitespace and a + or - at the start. If you wanted to handle user errors gracefully here, take a look at Asking the user for input until they give a valid response for more advanced options.
