我在尝试调用 datetime.date.day() 时遇到错误

Question

当我运行以下代码时，我在下面收到此回溯错误：

from datetime import date

def main():
    today = date.day()
    print("today is ", today)


if __name__ == "__main__":
   main()

错误

Traceback (most recent call last):
  File "/Users/Documents/CODE X/loops/super_hero_mix.py", line 9, in <module>
    main()
  File "/Users/Documents/CODE X/loops/super_hero_mix.py", line 4, in main
    today = date.day()
TypeError: 'getset_descriptor' object is not callable

Answer 1

使用date.today()获取今天的日期。如果您需要一个月中的某天，请使用 date.today().day.

Answer 2

也许您想使用 date.today():

from datetime import date

def main():
    today = date.today()
    print("today is ", today)


if __name__ == "__main__":
   main()

输出：

today is  2021-09-06

Answer 3

如果你想得到今天的日期，你可以这样做：

from datetime import datetime

def main():
    today = datetime.now().date()
    print("today is ", today)


if __name__ == "__main__":
   main()

如果是您所在月份的某天：

from datetime import datetime 
datetime.now().date().day

如果是星期几，则使用：

from datetime import datetime
now = datetime.now()
print(now.strftime("%A"))
