Sorry, is there a question?

Looks like the wrong place to post this. But FYI here is a more concise version:

df = df.rename({x:y for x,y in zip(df.columns, new_col_list)})

Well..you can just dict(zip(l1, l2))

I am sorry, I just mark the example for this usage. Not question. Thanks

I am closing this as this is not a forum for examples. Maybe consider StackOverflow.
