摘要:当您需要计数和迭代中的值时,Pythonenumerate()允许您编写Pythonicfor循环。最大的优点enumerate()是它返回一个带有计数器和值的元组,因此您不必自己增加计数器。它还为您提供了更改计数器起始值的选项。 本文分享自华为云社区《Python enumerate():使用计数器简化循环》,作者:Yuchuan。

通常会创建第二个 for 循环,如下面的代码所示,以遍历该目录中的每个文件,并对它们执行某些操作。使用os.path.join()方法,我们可以将根目录和file_entry变量连接起来,以获取文件的路径。然后我们将这个文件路径打印到控制台上。例如,我们还可以将这个文件路径追加到一个列表中,然后对列表进行迭代以处理每个文件: ...
So even though 5, 5.0, and 5 + 0j are distinct objects of different types, since they're equal, they can't both be in the same dict (or set). As soon as you insert any one of them, attempting to look up any distinct but equivalent key will succeed with the original mapped ...
