Python：Pandas根据字符串长度过滤字符串数据

import pandas as pddf = pd.read_csv('filex.csv')df['A'] = df['A'].astype('str')df['B'] = df['B'].astype('str')mask = (df['A'].str.len() == 10) & (df['B'].str.len() == 10)df = df.loc[mask]print(df)

应用于filex.csv：

A,B123,abc1234,abcd1234567890,abcdefghij

上面的代码打印

 AB2  1234567890  abcdefghij
