python – TypeError：|：’str’和’bool’不支持的操作数类型

我有不同列的数据框用户.我的目标是添加列[uses_name],当密码与每个用户的名字或姓氏相同时,该列应为True.

例如,十二行中的[user_name]包含milford.hubbard.然后在[uses_name]中将为True,因为[password]和[last_name]是相同的.

为此,我使用正则表达式创建两列[first_name]和[last_name].当创建[uses_name]时,我遇到了问题操作符.我在pandas doc中更多地了解布尔索引,但没有找到答案.

我的代码：

import pandas as pd

users = pd.read_csv('datasets/users.csv')

# Extracting first and last names into their own columns

users['first_name'] = users['user_name'].str.extract(r'(^\w+)', expand=False)

users['last_name'] = users['user_name'].str.extract(r'(\w+$)', expand=False)

# Flagging the users with passwords that matches their names

users['uses_name'] = users['password'].isin(users['first_name'] | users['last_name'])

# Counting and printing the number of users using names as passwords

print(users['uses_name'].count())

# Taking a look at the 12 first rows

print(users.head(12))

当我尝试编译它时,我给出了一个错误：

TypeError: unsupported operand type(s) for |: 'str' and 'bool'

用户数据框中的前12行,创建了first_name和last_name列：

解决方法:

这有效：
users [‘uses_name’] =(users [‘password’] == users [‘first_name’])| (用户[ ‘密码’] ==用户[ ‘姓氏’])
