Python实现计算文件夹下.h和.cpp文件的总行数

平时自己写了很多代码，但从没好好计算总共写了多少行，面试时被问起来，就傻了。。。闲来无事，写个python程序来统计下

import os################################################################################def calcLine(baseDir):  lineCount = 0  try:    for fileName in os.listdir(baseDir):      fullPath = baseDir + fileName      if os.path.isdir(fullPath):        lineCount += calcLine(fullPath + '//') #递归读取所有文件              if os.path.splitext(fullPath)[1] in (".h", ".cpp"):        file = open(fullPath)        for eachLine in file.readline():          lineCount += 1        file.close()          except Exception as e:    print(e)  return lineCount################################################################################if __name__ == "__main__":  baseDir = "K://C++//MFC//BubbleDragon//"  lineCount = calcLine(baseDir)  print(lineCount)
