利用python 统计源码行数，python统计源码行数,原理先获取所有文件，然后

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。```pythonimport osimport os.pathimport timerootdir = '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)```
