在目录中的所有文件上运行python脚本 [英] Running a python script on all the files in a directory

问题描述

我有一个Python脚本，通过文本csv文件读取并创建播放列表文件。但我只能一次做一个，如：

I have a Python script that reads through a text csv file and creates a playlist file. However I can only do one at a time, like:

python playlist.py foo.csv foolist.txt

但是，我有一个文件目录，需要制作成播放列表，有不同的名称，文件数目。

However, I have a directory of files that need to be made into a playlist, with different names, and sometimes a different number of files.

到目前为止，我已经查看了创建一个txt文件，列出目录中文件的所有名称，然后循环遍历，但我知道必须有一个更简单的方法来做。

So far I have looked at creating a txt file with a list of all the names of the file in the directory, then loop through each line of that, however I know there must be an easier way to do it.

推荐答案

for f in *.csv; do
  python playlist.py "$f" "${f%.csv}list.txt"
done

这会有什么好处吗？这会将foo.csv放在foolist.txt中，并将abc.csv放在abclist.txt中。

Will that do the trick? This will put foo.csv in foolist.txt and abc.csv in abclist.txt.

还是你想将它们全部放在同一个文件中？

Or do you want them all in the same file?
