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

* is a special character in regex, you have to escape it:

football.replace(['\*','-'], ['0.00','0.00'], regex=True).astype(np.float64)

or use a character class:

football.replace([*-], '0.00', regex=True).astype(np.float64)
