print(\'literal\', var1, var2) # literal abc xyz

... except for automat

Answer 1

Passing strings as arguments to print joins them with the 'sep' keyword. Default is ' ' (space).

Separator keyword is Python 3.x only. Before that the separator is always a space, except in 2.5(?) and up where you can from __future__ import print_function or something like that.

>>> print('one', 'two') # default ' '
one two
>>> print('one', 'two', sep=' and a ')
one and a two
>>> ' '.join(['one', 'two'])
one two
>>> print('one' + 'two')
