python每日一练：0007题

第 0007 题： 有个目录，里面是你自己写过的程序，统计一下你写过多少行代码。包括空行和注释，但是要分别列出来。

# -*- coding:utf-8 -*-
import os

def countCode(path):
    if not os.path.exists(path):
        print('路径不存在！')
    else:
        fileNameList = os.listdir(path)
        for fileName in fileNameList:
            nbspCount = 0
            commentCount = 0
            codeCount = 0
            multiCommentEndFlag = 0
            if ('.py' in fileName) and (fileName[-3:] == '.py'):
                with open(path+'\\'+fileName,encoding='utf-8') as f:
                    code = f.readlines()
                    for i in code:
                        codeCount += 1
                        i = i.strip()
                        if multiCommentEndFlag == 1:   #多行注释中内容
                            commentCount += 1
                            if len(i) >= 3 and (i[-3:] == '\'\'\'' or i[-3:] == '\"\"\"'): #多行注释结尾
                                multiCommentEndFlag = 0
                        elif len(i) >= 3 and (i[0:3] == '\'\'\'' or i[-3:] == '\"\"\"'):    #多行注释开头
                            commentCount += 1
                            multiCommentEndFlag = 1
                            if len(i) > 3 and (i[-3:] == '\'\'\'' or i[-3:] == '\"\"\"'):   #多行注释符在同一行的情况
                                multiCommentEndFlag = 0
                        elif i == '':   #空行
                            nbspCount += 1
                        elif len(i) >= 1 and i[0] == '#':   #单行注释（#）
                            commentCount += 1
                print('{0}中代码行数为：{1}，其中空行数：{2}，注释数：{3}'.format(fileName, codeCount, nbspCount, commentCount))

    countCode(r'C:\Users\Admin\PycharmProjects\untitled\python每日一练')
