os.path.exists和os.path.isfile之间的区别？ [英] Difference between os.path.exists and os.path.isfile?

问题描述

我很好奇这两个函数何时将返回不同的值。另外，如果您可以弄清路径/目录/文件之间的区别，将不胜感激。

I'm curious when these two functions will return different values. Also if you could clarify the difference between a path/directory/file that would be appreciated.

推荐答案

您已经发现，存在和 isfile 之间的区别是前者返回 True （如果给定路径是目录或文件），而如果路径指向文件，则后者仅返回 True 。

As you have already found out, the difference between exists and isfile is the fact that the former returns True in case the given path is a directory or a file, while the latter only returns True if the path points to a file.

目录和文件从技术角度来看非常相似。文件可以包含任何类型的数据。目录只是文件系统中的一个特殊条目（至少在Unix操作系统上，它只是一个特殊文件），它表示它可能包含文件和其他目录。这是建立数据结构的有用方法。使用目录，您可以按层次结构组织数据。

Directories and files are quite similar from the technical point of view. A file can contain any kind of data. A directory is just a special entry in the file system (at least on Unix operating systems it is just a special file) that represents the fact that it may contain files and other directories. It is a helpful means for building up a data structure. Using directories, you can organize your data in a hierarchical structure.

在Windows世界中，目录通常被称为文件夹。我确信您自己正在使用文件夹来组织文件。

Especially in the Windows world, directories are often called "folders". I am sure that you yourself are using "folders" for organizing your files.

路径是指向文件中资源的明确指针。系统。它可以指向文件或目录。

A path is an unambiguous pointer to a resource in the file system. It can either point to a file or to a directory.
