在python中查找文件

os.walk是答案，它将找到第一个匹配项：

import osdef find(name, path):    for root, dirs, files in os.walk(path):        if name in files: return os.path.join(root, name)

这将找到所有匹配项：

def find_all(name, path):    result = []    for root, dirs, files in os.walk(path):        if name in files: result.append(os.path.join(root, name))    return result

这将匹配一个模式：

import os, fnmatchdef find(pattern, path):    result = []    for root, dirs, files in os.walk(path):        for name in files: if fnmatch.fnmatch(name, pattern):     result.append(os.path.join(root, name))    return resultfind('*.txt', '/path/to/dir')
