Easiest way is to surround the boolean variable with repr()

flag = True
'{:<10}'.format(repr(flag))

An alternative is to just use something like:

["False     ","True      "][flag]

making sure the two strings are of the same length.

(You didn't specify version, but I tested these with CPython 2.7.3)
