The pandas.Series.map() performs the mapping by first matching the values of the outer Series with the index labels of the inner Series. It then returns a new Series, with the index labels of the outer Series but the values from the inner Series.
s2=pd.Series([4,5,6],index=['a','b','d'],name='s2') df['s2']=s2 Out: This method is equivalant to left join: d2.join(s2,how='left',inplace=True) To get the same result as Part 1, we can use outer join: d2.join(s2,how='outer',inplace=True)...
Replace index_to_rename with the index of the column you want to rename, and provide the desired new column name. What does the inplace=True parameter do? The inplace=True parameter in pandas is used to perform operations directly on the original object (DataFrame or Series) without the ...
