Cannot figure out what is wrong

return is a value. in order to use it you need to assign it to a variable:

1 2 3 4 5

def ask_weight():     lbs = float(input("How many pounds do you weigh? "))     return lbs weight = ask_weight() print str(weight)

If you are using Python 2.x as was suggested, you should be using 'raw_input' rather than 'input'.

Alright, you are going to hate me for this... First of all, I do have an idea of return functions, I just am not able to realize a difference between them and prints. Secondly, I found out the reason why nothing popped up was because of line 39 and this wonderful command called break. As it was defining my functions, I think it read break as a cue to stop defining and to end the program. The second I removed the break command, it started working.

Thank you for teaching me so much though (especially the format command, that will be a life saver in the future.)

Consider this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

def pow(number, power): # calculating an exponent     result = 1     for _ in range(power):         result = result * number          # the function always returns a value. If you do not specify what will be that value it will be None.     # So, you may print it or just generate it some way. But outside of the function, this variable will be untouchable.     # If you put raw materials in some kind of super duper sophisticated machine it may produce a laptop.     # But if there is no functionality to get the production out good for you - no laptop. :D     # So here it is - the return statement      return result   powers = [] for num in range(1,5):     power = pow(num, 3) # here the result of the pow() is returned and assgned to a variable.     powers.append(power)   print(powers)

Output:
[1, 8, 27, 64]
