[英]NameError: name 'datetime' is not defined
I'm teaching myself Python and was just "exploring".我正在自学 Python,只是在“探索”。 Google says that datetime is a global variable but when I try to find todays date in the terminal I receive the NameError in the question title? Google 说 datetime 是一个全局变量,但是当我尝试在终端中查找今天的日期时,我在问题标题中收到了 NameError?
