The functions return strings, so you can split them into lines:

rows_a = calendar.month(year_a, month).splitlines()
rows_b = calendar.month(year_b, month).splitlines()

You can then zip them together:

rows = ['{}    {}'.format(row_a, row_b) for row_a, row_b in zip(rows_a, 
rows_b)]

However:

1. The 2 months might have a different number of rows. 'zip' will 
truncate to the shorter one, so use itertools.zip_longest instead (give 
it a fillvalue of '').

2. The lines aren't all the same length, so you'll need to pad the 
left-hand one to the correct length (20 characters) to make everything 
line-up.
