'float' object not iterable?

Question

I'm trying to aggregate total rainfall in inches to display the total but when I run the code I get a TypeError saying that "'float' object is not iterable". Any idea what I've done wrong?

months = 12

def main():

    rain = get_rain()

    total = get_total(rain)

    avg = total / len(rain)

    low = min(rain)

    high = max(rain)

    print('The total rainfall in inches for the year is: ', format(total, ',.2f'))
    print()
    print('The average monthly rainfall this year was: ', format(avg, ',.2f'))
    print()
    print('The lowest rainfall in inches this year was: ', format(low, ',.2f'))
    print()
    print('The highest rainfall in inches this year was: ', format(high, ',.2f'))
    print()

def get_rain():

    rain_in = []

    print('Enter the amount of rainfall in inches for each month of the year.')
    print('------------------------------------------------------')

    for index in range(months):
          print('Enter the total rainfall in inches for month #', index + 1, ': ', sep='', end='')
          rain_inches = float(input())

          rain_in.append(rain_inches)

    return rain_inches

def get_total(rain_in_list):

          total = 0.0

          for num in rain_in_list:
              total += num

          return total

main()

Traceback:

    for num in rain_in_list:
TypeError: 'float' object is not iterable

Even a bit of a push in the right direction would help. I feel like I'm right on the edge of figuring this out.

input() accepts a prompt string, so it's better to use input("Enter the amount of rainfall..."). — Mechanical snail

Unrelated to your exception: You may be able to simplify some of your print calls by using the str.format method rather than the built-in format function. For instance, print('The total rainfall in inches for the year is: {.2f}'.format(total)). For your input prompt, you can do this formatting right in the input call (it will be printed at the start of the line where the input is requested): input('Enter the total rainfall in inches for month #{}: '.format(index + 1)) — Blckknght

Just a note: Your get_toal function already exists in Python. It is called sum. — Ryan C. Thompson

Thanks for the tips guys! @blckknght- this is some helpful advice, I'll play with this and see what I can learn :) ryanthompson- makes sense, how would I implement this? — RobertJRodriguez

In get_rain you return

return rain_inches #float

instead of

return rain_in #list

Ahh! So easily overlooked. Will make the adjustment and hopefully not miss that again. Thanks!
