Pandas Python Regex : error: nothing to repeat

Question

I have a dataframe with a couple of strange characters, \"*\" and \"-\".

import pandas as pd
import numpy as np

data = {\'year\': [2010, 2011, 2012, 2011,          


        

Answer 1

Do

football.replace(['*','-'], ['0.00','0.00'], regex=False)

That is, there is no need to use regular expression for a simple case of matching just 1 character or another;

or if you want to use regular expression, do note that * is a special character; if you want to match values that are '*' or '-' exactly, use

football.replace('^[*-]$', '0.00', regex=True)
