Change column name with a .0 in Pandas










1














I have a dataframe with columns as Country, 2015.0,2016.0,2017.0 these are suppose to be years. But the column name has .0 in it. I tried to rename them but rename is not working. I am not able to remove the .0 at the end.
Any suggestions.

  • dataframe.columns = ['Country', '2015', '2016', '2017'] doesn't work?

  • This will work but I have last 50 years of data, is there a better way to do it?

  • dflst = dataframe.columns.tolist() will get you a list of columns, you could do something like dflist.pop('Country'), dflst = ['Country'] + list(map(int, dflist)) and then put them back with dataframe.columns = dflst. Just make sure your columns are lined up right afterwards.
