【Python】AttributeError: ‘DatetimeProperties’ object has no attribute ‘weekday_name’ 的解决方法

import pandas as pd

# 创建日期
dates = pd.Series(pd.date_range("2/2/2002", periods=3, freq="M"))
# 查看星期几
print(dates.dt.weekday_name)
# 只显示数值
print(dates.dt.weekday)

AttributeError: ‘DatetimeProperties’ object has no attribute ‘weekday_name’

weekday_name改为day_name()

import pandas as pd

# 创建日期
dates = pd.Series(pd.date_range("2/2/2002", periods=3, freq="M"))
# 查看星期几
print(dates.dt.day_name())
# 只显示数值
print(dates.dt.weekday)
