如何在多级子目录中查找文件 [英] How to find files in multilevel subdirectories

问题描述

假设我有一个包含多个子目录的目录:

Suppose I have a directory that contains multiple subdirectories:

one_meter = r"C:\Projects\NED_1m"

在目录one_meter中，我想找到所有以'.xml'结尾并包含字符串"_meta"的文件.我的问题是，某些子目录的文件级别为1级，而其他子目录的级别则为2级 例如:

Within the directory one_meter I want to find all of the files that end with '.xml' and contain the string "_meta". My problem is that some of the subdirectories have that file one level donw, while others have it 2 levels down EX:

one_meter > USGS_NED_one_meter_x19y329_LA_Jean_Lafitte_2013_IMG_2015 > USGS_NED_one_meter_x19y329_LA_Jean_Lafitte_2013_IMG_2015_meta.xml
one_meter > NY_Long_Island> USGS_NED_one_meter_x23y454_NY_LongIsland_Z18_2014_IMG_2015 > USGS_NED_one_meter_x23y454_NY_LongIsland_Z18_2014_IMG_2015_meta.xml

我想查看我的主目录(one_meter') and find all of the _meta.xml files (regardless of the subdirectory) and append them to a list ( one_m_lister = []`). 我尝试了以下操作，但未产生任何结果.我在做什么错?

I want to look in my main directory (one_meter') and find all of the_meta.xmlfiles (regardless of the subdirectory) and append them to a list (one_m_lister = []`). I tried the following but it doesn't produce any results. What am I doing incorrectly?

one_m_list = []
for filename in os.listdir(one_meter):
    if filename.endswith(".xml") and "_meta" in filename:
        print(filename)
        one_m_list.append(filename)

推荐答案

@JonathanDavidArndt的回答很好，但已经过时了.从Python 3.5开始，您可以使用 pathlib.Path.glob 在任何子目录中搜索模式.

The answer of @JonathanDavidArndt is good but quite outdated. Since Python 3.5, you can use pathlib.Path.glob to search a pattern in any subdirectory.

例如:

import pathlib

destination_root = r"C:\Projects\NED_1m"
pattern = "**/*_meta*.xml"

master_list = list(pathlib.Path(destination_root).glob(pattern))
