pandas如何处理一列中有汉字也有数值

处理一：代码如下

import numpy as np

def is_number(s):

    try:

        float(s)

        return True

    except ValueError:

        pass

 

    try:

        import unicodedata

        unicodedata.numeric(s)

        return True

    except (TypeError, ValueError):

        pass

 

    return False

df['语文']=df['语文'].map(lambda x:np.where(is_number(x),x,0))

df[df['数学'].apply(lambda x: isinstance(x, str))].index

#

Int64Index([10], dtype='int64')
df.drop(df[df['数学'].apply(lambda x: isinstance(x, str))].index)
