Help Formatting Print Statement (input from 3 lists) X 2

[Hebruiser]

@wavic, I see what you're getting at, however, i have no idea how to implement that into my code. For example, is this going to be its own line of code, or will it be wrapped into one of the fileWrite lines? I put them all together in one line and it didn't like it. I got:
File "/Users/jaywinfrey/PycharmProjects/Project IV.py", line 2, in data_save
str.join('::'.join(now), '::'.join(cust_name), '::'.join(street), '::'.join(city), '::'.join(state),
TypeError: can only join an iterable
