问题描述

因此，如果我有一个类似以下的目录，则可以通过它的名称扫描带有特定代码的文件数量.例如，如果我想从17042020开始的文件数在下面的目录中是6?

So if I have a directory like below is there a way to scan how many files with a specific code in its name. For example if I want the number of files that start with 17042020 which would be 6 from the directory below?

1704202001-01.csv
1704202001-02.csv
1704202002-01.csv
1704202002-02.csv
1704202003-01.csv
1704202003-02.csv

推荐答案

，您可以使用 pathlib 模块或简单的 glob :

you can use the pathlib module or just plain glob :

 from pathlib import Path
 folder = Path(dir_of_files)
 specific_files = list(folder.glob('1704202001-*.csv')
 #or : list(folder.rglob('1704202001-*.csv') ... this will recursively search thru every subfolder for files that match this

 print(specific_files)
