原理先获取所有文件,然后统计每个文件中代码的行数,最后将行数相加,思路很简单。
代码语言:javascript复制import os
import os.path
import time
rootdir = '文件路径'
filelists = []
遍历文件
def getFile(rootdir):
global filelists
for parent,dirnames,filenames in os.walk(rootdir):
for dirname in dirnames:
getFile(os.path.join(parent,dirname)) #嵌套
for filename in filenames:
#print "filename is:" filename
filelists.append(os.path.join(parent,filename))
统计一个文件的行数
def countLine(fname):
count = 0
for file_line in open(fname).xreadlines():
if file_line != '' and file_line != 'n': #过滤掉空行
count = 1
print fname '.....' , count
return count
if name == 'main' :
startTime = time.clock()
getFile(rootdir)
totalline = 0
for filelist in filelists:
totalline = totalline countLine(filelist)
print 'totalline:',totalline
print 'done:%0.2f second' % (time.clock() - startTime)</pre>
