pandas-paddles's Issues
Make `S` also work with Index objects
It would be nice, if S could also be used on DataFrame.columns, e.g.
col_subset = df.columns[S.str.startswith('prefix_')]Currently, this fails, because pandas.Index is not a sub-class of pandas.Series.
Usage in groupby()[col].agg() fails due to function name not being resolved
Example stack-trace:
[...]
File /site-packages/pandas/core/apply.py:1517, in _managle_lambda_list(aggfuncs)
1515 mangled_aggfuncs = []
1516 for aggfunc in aggfuncs:
-> 1517 if com.get_callable_name(aggfunc) == "<lambda>":
1518 aggfunc = partial(aggfunc)
1519 aggfunc.__name__ = f"<lambda_{i}>"
TypeError: __bool__ should return bool, returned SeriesContext
Allow passing slices to C[...] and I[...]
Would be cool to allow combining slices of columns, e.g., when working with Excel-like named columns (A, B, ...):
C["A":"D"] | C["U":"X"]Recommend Projects
