python实现代码行数统计示例分享

代码如下:

#!/usr/bin/python

'''
File : count.py
Author : Mike
E-Mail : [e-mail]
'''
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(".")

print "files count : ",filesCount
print "lines count : ",linesCount

raw_input("Press Enter to continue")

使用方法
1、针对本目录

代码如下:

./count.py

2、统计多个目录

代码如下:

./count.py /tmp ~
