pandas.Panel.any

Panel.any(axis=0, bool_only=None, skipna=True, level=None, **kwargs) [source]

Return whether any element is True over requested axis.

Unlike DataFrame.all(), this performs an or operation. If any of the values along the specified axis is True, this will return True.

Parameters:

axis : {0 or ‘index’, 1 or ‘columns’, None}, 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.
  • 1 / ‘columns’ : reduce the columns, return a Series whose index is the original index.
  • None : reduce all axes, return a scalar.

skipna : boolean, default True

Exclude NA/null values. If an entire row/column is NA, the result will be NA.

level : int or level name, default None

If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a DataFrame.

bool_only : boolean, default None

Include only boolean columns. If None, will attempt to use everything, then use only boolean data. Not implemented for Series.

**kwargs : any, default None

Additional keywords have no effect but might be accepted for compatibility with NumPy.

Returns:
any : DataFrame or Panel (if level specified)

pandas.DataFrame.all
Return whether all elements are True.

Examples

Series

For Series input, the output is a scalar indicating whether any element is True.

>>> pd.Series([True, False]).any()
True

DataFrame

Whether each column contains at least one True element (the default).

>>> df = pd.DataFrame({"A": [1, 2], "B": [0, 2], "C": [0, 0]})
>>> df
   A  B  C
0  1  0  0
1  2  2  0
>>> df.any()
A     True
B     True
C    False
dtype: bool

Aggregating over the columns.

>>> df = pd.DataFrame({"A": [True, False], "B": [1, 2]})
>>> df
       A  B
0   True  1
1  False  2
>>> df.any(axis='columns')
0    True
1    True
dtype: bool
>>> df = pd.DataFrame({"A": [True, False], "B": [1, 0]})
>>> df
       A  B
0   True  1
1  False  0
>>> df.any(axis='columns')
0    True
1    False
dtype: bool

Aggregating over the entire DataFrame with axis=None.

>>> df.any(axis=None)
True

any for an empty DataFrame is an empty Series.

>>> pd.DataFrame([]).any()
Series([], dtype: bool)
