BUG: DataFrame.any() inconsistent with other methods · Issue #57087 · pandas-dev/pandas (original) (raw)

Pandas version checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandas.
• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd

df = pd.DataFrame({'x':[1,2,3],'y':[1,2,3]})

df.all(0) # Positioned arg for axis is allowed. df.any(0) # Positioned arg for axis not allowed.

Issue Description

The any method has a keyword only restriction for its arguments. The all method doesn't.

Expected Behavior

any and all should be consistent. To my POV any seems to be doing the right thing, while all (and other similar methods without a restriction and default arguments only, min, max etc) seems to be going against what Pandas has been moving toward where all arguments with defaults tend to fall on the keyword only side of the argument list.

Which is correct?
