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。 [code] 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) 关于代码上的分析就到这里，例子比较简单。
