如何在python中查找文件

import os

def find_files(directory, extension):
    result = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith(extension):
                result.append(os.path.join(root, file))
    return result

directory = "/path/to/directory"
extension = ".txt"
files = find_files(directory, extension)
print(files)

import glob

directory = "/path/to/directory"
extension = "*.txt"
files = glob.glob(os.path.join(directory, extension))
print(files)

import fnmatch

directory = "/path/to/directory"
extension = "*.txt"
files = [os.path.join(directory, file) for file in os.listdir(directory) if fnmatch.fnmatch(file, extension)]
print(files)
