如何使用Python查找文件？
要使用python在目录中查找文件，您可以使用目录树os.walk查找文件，如下所示-
示例
import os
def find_file(file_name, directory_name):
files_found = []
for path, subdirs, files in os.walk(directory_name):
for name in files:
if(file_name == name):
file_path = os.path.join(path,name)
files_found.append(file_path)
return files_found
find_file('my_file.txt', 'my_folder')当您运行此脚本并具有以下文件夹结构时-
my_folder/
another_folder/
my_file
another_file
hello.py
my_file输出结果你会得到输出-
['/my_folder/another_folder/my_file', '/my_folder/my_file']
