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

I needed to rename features for XGBoost, it didn't like any of these:

import re
regex = r"[!\"#$%&'()*+,\-.\/:;<=>?@[\\\]^_`{|}~ ]+"
X_trn.columns = X_trn.columns.str.replace(regex, '_', regex=True)
X_tst.columns = X_tst.columns.str.replace(regex, '_', regex=True)
