[Tutor] __name__=='__main__'

[Michael Lewis]

Now that I am better understanding '__name__'=='__main__', I need to get
advice on one last part. Since you put this in the file as an if statement,
some instruction must come after. What do you suggest putting after this
statement/is that piece of code ever put into action?
In my example below, I've done a few tests like putting a print statement
under '__name__'=='__main__' and it isn't printed. I am not sure what to
put in this code block.

def MultiplyText(text, multiplier):
    '''Recieve a S & int. For digits in S, multiply by multiplier and
return updated S.'''
    return ' '.join(str(int(num) * multiplier) if num.isdigit() else num
for num in text)


def GetUserInput():
    '''Get S & multiplier. Test multiplier.isdigit(). Call
MultiplyText(text, multiplier)'''
    text = raw_input('Enter some text: ')
    while True:
        multiplier = raw_input('Enter a multiplier: ')
        try:
            multiplier = int(multiplier)
            break
        except ValueError:
            continue
    return MultiplyText(text.split(), multiplier)


if '__name__' == '__main__':
    GetUserInput()
