Nearly.
The circumference is wrong, you need to calculate it not read it from 
the user.

No, but your second variant is separate functions. You just need to 
insert them into the first version as appropriate. (After you get them 
working of course!:-)

This line needs to be an input as you did above.
All you are doing here is printing a message not reading anything back.
And certainly not assigning anything to width.

That defines the function but does not call it. You should put the 
definition outside the loop - above all the code above - and then call 
it inside the if/else statement:

area = get_area_of_square()

or even

print "Area of square = ", get_area_of_square()
