计算程序总行数的Python代码

最近需要统计一下项目中代码的总行数，写了一个Python小程序，不得不说Python是多么的简洁，如果用Java写至少是现在代码的2倍。

import os
path="/Users/rony/workspace/ecommerce/ecommerce/hot-deploy/"
global totalcount
totalcount =0
def cfile (path):
    allfiles = os.listdir(path)
    for file in allfiles:
        child = os.path.join(path,file)
        if os.path.isdir(child):
            cfile(child)
        else:
            filename,fileext= os.path.splitext(child)
            print(fileext)
            #file type need to calculate
            if fileext in ['.java', '.jsp', '.html', '.htm', '.xml', '.sql', '.js', '.ftl', '.css','.groovy'] :
                countf = len(open(child,'rU').readlines())
                global totalcount
                totalcount=totalcount+countf;
                print(child)
                print(countf)
cfile(path)
print(totalcount)
