W1305 (format-combined-specification)
Problematic code:
print('{} {1}'.format('hello', 'world'))
Correct code:
print('{0} {1}'.format('hello', 'world'))
# or
print('{} {}'.format('hello', 'world'))
Rationale:
Used when a PEP 3101 format string contains both automatic field numbering
(e.g. {}) and manual field specification (e.g. {0}).
