之前用bash實現過（//www.jb51.net/article/61943.htm），不過那個不能在windows下使用，所以就寫了個python版，也方便我以后使用……這里就不多介紹了，不懂的google下。

實現代碼
代碼如下:
#!/usr/bin/python

'''
        File      : count.py

import sys,os

extens = [".c",".cpp",".hpp",".h"]
linesCount = 0
filesCount = 0

def funCount(dirName):
    global extens,linesCount,filesCount
    for root,dirs,fileNames in os.walk(dirName):
        for f in fileNames:
            fname = os.path.join(root,f)
            try :
                ext = f[f.rindex('.'):]
                if(extens.count(ext) > 0):
                    print 'support'
                    filesCount += 1
                    print fname
                    l_count = len(open(fname).readlines())
                    print fname," : ",l_count
                    linesCount += l_count
                else:
                    print ext," : not support"
            except:
                print "Error occur!"
                pass

if len(sys.argv) > 1 :
    for m_dir in sys.argv[1:]:       
        print m_dir
        funCount(m_dir)
else :
    funCount(".")
