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)
