Renaming columns in pandas

Question

I have a DataFrame using pandas and column labels that I need to edit to replace the original column labels.

I\'d like to change the column names in a DataFrame

Answer 1

Another option is to rename using a regular expression:

import pandas as pd
import re

df = pd.DataFrame({'$a':[1,2], '$b':[3,4], '$c':[5,6]})

df = df.rename(columns=lambda x: re.sub('\$','',x))
>>> df
   a  b  c
0  1  3  5
1  2  4  6
