Python:这两个 import 语句有什么区别?

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

问题描述

在我看来，它们在功能上都一样.使用其中一种有什么区别和优势吗?

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

如果你将导入包裹在括号中，如果你在导入语句中放置一个换行符，你就不必使用反斜杠来续行，即首选样式.在功能上，它们是相同的，如果在一行中，省略括号会更干净.

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.
