pyspark.pandas.Index.all

Index.all(axis: Union[int, str] = 0, skipna: bool = True) → bool

Return whether all elements are True.

Returns True unless there at least one element within a series that is False or equivalent (e.g. zero or empty)

Parameters
axis{0 or ‘index’}, default 0

Indicate which axis or axes should be reduced.

  • 0 / ‘index’ : reduce the index, return a Series whose index is the original column labels.

skipnaboolean, default True

Exclude NA/null values. If an entire row/column is NA and skipna is True, then the result will be True, as for an empty row/column. If skipna is False, then NA are treated as True, because these are not equal to zero.
