Python代码行统计脚本

一个超简单的Python代码行统计程序：

# -*- coding:utf8 -*-
import os
import sys
sys.getdefaultencoding()

sumline = 0
endsuffix = ['py']
# 将下面的路径换成你本地要统计的路径
path = r'E:\VAL\validation\Automatic_Test'
for dirpath, dirnames, filenames in os.walk(path):
    flist = filter(lambda filename: filename.split('.')[-1] in endsuffix and filename.strip(), filenames)
    if len(flist) == 0:
        continue
    sumline += reduce(lambda x, y: x + y, map(lambda filename: len(open(dirpath + os.sep + filename).readlines()), flist))

print sumline
