搜索目录中的字符串

Question

您好我编写了此代码，用于在文件列表中搜索关键字

import glob
import os
print "enter directory path"
path=raw_input()
print "Enter keyword"
key=raw_input()
os.chdir(path)
for files in glob.glob("*.*"):
    with open(file) as f:
         contents=f.read()
    if key in contents:
          print file

我对Python比较陌生。任何人都可以帮我修改同样的子目录搜索吗？

使用os.walk：

for root, dirs, files in os.walk(your_dir_path):
    for file in files:
        file = os.path.join(root, file)    
        with open(file) as f:
             ...
