result.fillna(0)
and replace

result.replace(r'\s+', np.nan, regex=True)
However, both with no success.
然而,两者都没有成功。

You are creating a copy of the dataframe but the original one is not keeping the changes, you need to specify "inplace=True" if you want the dataframe to persist the changes
您正在创建数据框的副本,但原始副本没有保留更改,如果您希望数据框保留更改,则需要指定“inplace=True”
result.fillna(0, inplace=True)
