pandas.Series.update#

Series.update(other)[source]#

Modify Series in place using values from passed Series.

Uses non-NA values from passed Series to make updates. Alignson index.

Parameters:

otherSeries, or object coercible into Series

Examples

>>>s=pd.Series([1,2,3])>>>s.update(pd.Series([4,5,6]))>>>s0    41    52    6dtype: int64

>>>s=pd.Series(['a','b','c'])>>>s.update(pd.Series(['d','e'],index=[0,2]))>>>s0    d1    b2    edtype: object

>>>s=pd.Series([1,2,3])>>>s.update(pd.Series([4,5,6,7,8]))>>>s0    41    52    6dtype: int64

Ifother contains NaNs the corresponding values are not updatedin the original Series.

>>>s=pd.Series([1,2,3])>>>s.update(pd.Series([4,np.nan,6]))>>>s0    41    22    6dtype: int64

other can also be a non-Series object typethat is coercible into a Series

>>>s=pd.Series([1,2,3])>>>s.update([4,np.nan,6])>>>s0    41    22    6dtype: int64

>>>s=pd.Series([1,2,3])>>>s.update({1:9})>>>s0    11    92    3dtype: int64
