【Python】统计代码行数

作者:蓝鲸肚子 / 发布于2012/5/26/ 935

输入一个目录，统计目录及子目录下所有代码的总行数。初学python，参考了Moody _"Kuuy"_ Wizmann的相关代码。也可以用shell命令直接统计，例如统计当前目录下的cpp文件总行数： find ./ -name "*.cpp" | xargs cat | wc -l

<div>/usr/bin/python
import os</div>
<div>count the line of a single file
def CountLine(path):
 tempfile = open(path)
 res = 0
 for lines in tempfile:
 res += 1
 print "%s %d" %(path, res) #output the file path and lines
 return res</div>
<div>count the total line of a folder, sub folder included
def TotalLine(path):
 total = 0
 for root, dirs, files in os.walk(path):
 for item in files:
 ext = item.split('.')
 ext = ext[-1] #get the postfix of the file
 if(ext in ["cpp", "c", "h", "java", "py", "php"]):
 subpath = root + "/" + item
 total += CountLine(subpath)
 return total</div>
<div>print "Input Path"
path = raw_input()
print TotalLine(path)</div>
