python find file

import re
import os
import sys
import glob
base = os.path.abspath(os.path.dirname(__file__))
def find_file_by_pattern(pattern,base=".", circle=True):
prog = re.compile(pattern)
final_file_list = []
cur_list = os.listdir(base)
for item in cur_list:
full_path = os.path.join(base, item)
# print full_path
bfile = os.path.isfile(item)
if os.path.isdir(full_path):
final_file_list += find_file_by_pattern(pattern, full_path)
else:
value=prog.match(item)
if(value!=None):
final_file_list.append(full_path)
return final_file_list

print find_file_by_pattern("*.bak")

一段小代码，查找文件。记下来，以后方便时候用。
