E1302 (mixed-format-string)
Problematic code:
print('%(one)s %s' % ('hello', 'world'))
Correct code:
print('{} {}'.format('hello', 'world'))
Rationale:
Used when a format string contains both named (e.g. %(foo)d) and unnamed
(e.g. %d) conversion specifiers. This is also used when a named conversion
specifier contains * for the minimum field width and/or precision.
