Simple Question - ' defined as "a". ?'

[Ryan012]

Hi rob101

Thank you so much for your kind response and explaination.

I'm very beginner so..I have no idea what I have to do..

1) You mean I need to make a file - (1) a.py in the same directory,Right?

2) How can I Save this as the script that is doing the import ?

1
import a

3) I tried to run again but they showed me another error as the following:

AttributeError : module 'a' has no attribute 'sum'.

Thanks

Ryan.
