import os
def 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, fnmatch
def 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 result
find('*.txt', '/path/to/dir')
