pandas.Series.eq¶
- Series.eq(other, level=None, fill_value=None, axis=0)[source]¶
Return Equal to of series and other, element-wise (binary operator eq).
Equivalent to
series == other, but with support to substitute a fill_value for missing data in either one of the inputs.- Parameters
- otherSeries or scalar value
- levelint or name
Broadcast across a level, matching Index values on the passed MultiIndex level.
- fill_valueNone or float value, default None (NaN)
Fill existing missing (NaN) values, and any new element needed for successful Series alignment, with this value before computation. If data in both corresponding Series locations is missing the result of filling (at that location) will be missing.
- axis{0 or ‘index’}
Unused. Parameter needed for compatibility with DataFrame.
- Returns
- Series
The result of the operation.
Examples
>>> a = pd.Series([1, 1, 1, np.nan], index=['a', 'b', 'c', 'd']) >>> a a 1.0 b 1.0 c 1.0 d NaN dtype: float64 >>> b = pd.Series([1, np.nan, 1, np.nan], index=['a', 'b', 'd', 'e']) >>> b a 1.0 b NaN d 1.0 e NaN dtype: float64 >>> a.eq(b, fill_value=0) a True b False c False d False e False dtype: bool
