Python：这两个import语句有什么区别？ [英] Python: What is the difference between these two import statements?

问题描述

它们在功能上对我来说都是一样的。使用一个是否有任何差异和优势？

They both functionally looks same to me. Are there any differences and advantages of using one over another?

>>> from datetime import datetime, timedelta
>>> from datetime import (datetime, timedelta)

推荐答案

如果你换行如果在import语句中添加换行符，则不必使用反斜杠作为行继续，这是首选样式。从功能上来说，它们是相同的，如果在一条线上，那么将它们排除在外是很清洁的。

If you wrap the imports in parens, you don't have to use a backslash for line continuation if you put a line break in the import statement, which is the preferred style. Functionally, they are identical, and if on one line, leaving out the parens is cleaner.
