Trying to rename a column in a Data frame. I used the same line to rename the column "frames"

I want to rename a column from a "0" to "Grad"

result = pd.concat([table2, tableg3], axis=1)
result.rename(columns = {"0" : "Grad"}, inplace = True)
result

This outputs

CodePudding user response：

You forgot to assign the result

result=result.rename…

Or use inplace=True

Common mistake with pandas.

CodePudding user response：

"0" - string
0 - var

You havce to use {0 : "Grad"}

result.rename(columns = {0 : "Grad"}, inplace = True)

CodePudding user response：

Have you tried {0 : "Grad"}? What is the output of result.columns?
