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)
