pandas.Series.div#

Series.div(other, level=None, fill_value=None, axis=0)[source]#

Return Floating division of series and other, element-wise (binary operator truediv).

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: Series with which to compute division.
levelint or name: Broadcast across a level, matching Index values on the passed MultiIndex level.
fill_valuescalar or None, default None: Fill NA values, whether present in the original data or introduced by alignment, with this value before computation. Positions where both inputs are NA are left unfilled and behave as NA does for the operation.
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.divide(b, fill_value=0)
a    1.0
b    inf
c    inf
d    0.0
e    NaN
