How to repeat characters in Python without string concatenation? -

-

i'm writing short program frequency analysis. however, there's 1 line bothering me:

"{0[0]}  | " + "[]" * num_occurrences + " total: {0[1]!s}"

is there way in python repeat characters arbitrary number of times without resorting concatenation (preferably inside format string)? don't feel i'm doing in pythonic way.

the best way repeat character or string multiply it:

>>> "a" * 3 'aaa' >>> '123' * 3 '123123123'

and example, i'd use:

>>> "{0[0]}  | {1} total: {0[1]!s}".format(foo, "[]" * num_occurrences)
