df.loc[s, ]
and
df.loc[s]
are different code
the former is a 1-element tuple -- perhaps you meant to write df.loc[(s,)]
?

Thanks - I thought it might be something like that, but I couldn't get it straight in my head. I guess it's a quirk/design decision of pandas that df.loc[s]
and df.loc[s,]
/df.loc[(s,)]
should mean the same thing.
I suppose that the correct way to fix the conflict between flake8 (which prefers foo[1, ]
) and this tool (which prefers foo[1,]
) is to manually wrap the term in parentheses, i.e. foo[(1,)]
- this seems to satisfy both tools. (Or preferably remove the comma entirely, i.e. foo[1]
, if that doesn't change the behaviour.)

pandas may treat them the same, but they are not the same:
>>> class C:
... def __getitem__(self, x):
... print(x)
...
>>> c = C()
>>> c[1,]
(1,)
>>> c[1]
