# pandas.DataFrame.any

DataFrame.any(*, axis=0, bool_only=False, skipna=True, **kwargs)

  Return whether any element is True, potentially over an axis.

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

  Parameters:
    axis{0 or ‘index’, 1 or ‘columns’, None}, default 0

      Indicate which axis or axes should be reduced. For Series this parameter is unused and defaults to 0.

      - 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.

    bool_only bool, default False

      Include only boolean columns. Not implemented for Series.

    skipna bool, default True

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

    **kwargs any, default None

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

  Returns:
    Series or scalar

      If axis=None, then a scalar boolean is returned. Otherwise a Series is returned with index matching the index argument.

  Examples

  Series

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

      >>> pd.Series([False, False]).any()
      False
      >>> pd.Series([True, False]).any()
      True
      >>> pd.Series([], dtype="float64").any()
      False
      >>> pd.Series([np.nan]).any()
      False
      >>> pd.Series([np.nan]).any(skipna=False)
      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)
