It turns out pylint is lying. The situation is equivalent to

$ cat module.py
for format in [42]:
    pass
del format

$ cat main.py 
original_format = format
from module import *
assert format is original_format
$ python main.py

The assert doesn't trigger, so format is not redefined. But pylint complains 
anyway:

$ pylint main.py -rn
No config file found, using default configuration
************* Module main
W:  2: Redefining built-in 'format'
C:  1: Missing docstring
C:  1: Invalid name "original_format" (should match (([A-Z_][A-Z0-9_]*)|
(__.*__))$)
W:  2: Wildcard import module

If you can ignore the warning about the wildcard import you should be able 
to ignore the "redefining built-in" warning, too. Personally I would avoid 
putting magic comments like

from module import * # pylint: disable=W0622

$ pylint main.py -rn
No config file found, using default configuration
************* Module main
I:  2: Locally disabling W0622
C:  1: Missing docstring
C:  1: Invalid name "original_format" (should match (([A-Z_][A-Z0-9_]*)|
(__.*__))$)
W:  2: Wildcard import module

into the code.
