pandas.Series.truediv

Series.truediv(self, 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 one of the inputs.

Parameters
otherSeries or scalar value
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 will be missing.

levelint or name

Broadcast across a level, matching Index values on the passed MultiIndex level.

Returns
Series

The result of the operation.
