如何让python搜索整个硬盘 [英] How to make python search the entire HDD

问题描述

我正在为我的计算机制作一个简单的 python 搜索程序，我想知道如何让它扫描整个 C 驱动器以搜索文件，而不是该文件与目标文件位于同一文件夹中?这是我目前所拥有的.

I'm making a simple python search program for my computer and I was wondering how I would get it to scan the entire C Drive to search for a file, instead of the file being in the same folder as the target file? This is what I have so far.

import os

print('What song would you like to listen to?')
choice = input().title()
os.startfile(choice + '.mp3')

推荐答案

如果你有一个根目录来搜索，你可以使用 os.walk.它将产生目录路径、该目录中的目录和该目录中的文件名的三元组.例如，如果我们有这样的目录结构:

If you have a root directory to search within, you can use os.walk. It will yield triples of directory paths, directories within that directory, and filenames within that directory. For example, if we have this directory structure:

root
├── dir1
│   └── file1
├── dir2
│   └── subdir
│       ├── file1
│       ├── file2
│       └── file3
├── file1
└── file2

那么这段代码:

for path, dirnames, filenames in os.walk('root'):
    print((path, dirnames, filenames))

将打印:

('root', ['dir1', 'dir2'], ['file1', 'file2'])
('root/dir1', [], ['file1'])
('root/dir2', ['subdir'], [])
('root/dir2/subdir', [], ['file1', 'file2', 'file3'])

因此，如果您正在寻找 file3，您只需继续循环，直到您在 filenames 中看到 file3 (in 运算符 在这里是合适的).一旦你看到它，文件的完整路径是 os.path.join(path, 'file3')，你应该可以用 os.startfile 打开它.

So if you’re looking for a file3, you just keep looping until you see a file3 in filenames (the in operator would be appropriate here). Once you see it, the full path to the file is os.path.join(path, 'file3'), which you should be able to open with os.startfile.
