simple python help (VERY SIMPLE)

[littlepigboy5]

I was learning python before school started, then had to take a break for 2 weeks, now im getting back into it and i don't remember how to save the return value as a variable.  There may be some other things, I am going to attatch the instructions and what I have, please help.

Thanks

You aren't returning anything from average() is the problem. You just have return at the end. You need

return total / len(numbers)

[manikyath]

line 25 and 26:

return (total/ len(numbers))

[littlepigboy5]

 

line 25 and 26:

return (total/ len(numbers))

thank you

ignore this i got it

@littlepigboy5 Why post this in trouble shooting and not programming? I've never touched python before but I would assume it would be just like C++/C/C#/Java.

There's a lot more wrong than that. I'd suggest looking up a beginners tutorial that starts from the absolute basics that isn't codeacademy.

Like Fizzlesticks said, there's a lot of problematic stuff in the code here.  I'll second a recommendation for some basic introduction to Python.  That said, two ways to do what you're trying to do:

 

First, a very compact way, in two lines (including the def line).  You can write return [stuff], and if [stuff] is an expression or equation rather than a single variable or value, Python will return the value of that expression/equation.

def average(numbers):   return (sum(numbers) / len(numbers))

Second, a way that's much closer to how you've done it.

def average(numbers):    total = sum(numbers)    total = float(total) # Converts total to a float    total /= len(numbers) # equivalent to total = total / len(numbers)    return total

This one sums up all the input numbers, and stores that value in the variable total.  Then it converts total to a float and divides it by the length of the input list.  Finally it returns the variable total.

 

Note: if you're using Python 3, then you don't need to convert to a float value before dividing.
