课堂笔记随记10-pycharm使用技巧v0

1、思路分解：1- 获取文件中每一行的信息：学生 id 课程 id 签到时间2- 按照要求去统计3- 输出step over-单步运行每一行为一步def func():pr(1)pr(2)pr(3)pr(4)#1- 获取文件中每一行的信息：学生 id 课程 id 签到时间fileDir = rG:0005_1.txtdef putInfoToDict(fileName):resDict = #1- 打开文件with open(fileName) as fo:#2-所有行lines = fo.read().splitlines()#返回是 list#3- 对每一行进去提取数据-遍历for line

2、in lines:# info = #临时的字典line =line.replace(t,).replace(,).replace(),).replace(,)#切割 ,temp = line.split(,)checkTime = temp0lessonId =(temp1)userId =(temp2)#2- 按照要求去统计info = lessonid:lessonId, checkime:checkTime# infolessonid = lessonId# infocheckime = checkTimeif userId in resDict:#如果学生 id 在里面resDict

3、userId.append(info)else:#新增键值对import loggingLOG_FORMAT = %(asctime)s - %(levelname)s - %(message)sDATE_FORMAT = %m/%d/%Y %H:%M:%S %plog_file = G:/basic20200315.loglogging.basicConfig(filename=log_file,level=logging.DEBUG,formOG_FORMAT,datefmt=DATE_FORMAT)# logging.basicConfig(filename=log_file, leve

4、l=logging.DEBUG)logging.debug(this is a debugmsg!)(this is a infomsg!)logging.warning(this is a warn msg!)logging.error(this is a error msg!)logging.critical(this is a criticag!)时间级别重要数据异常信息等resDictuserId = info# func()return resDictres = putInfoToDict(fileDir)# pr(res)#完美打印import pprppr

5、.ppr(res)#json# import json# pr(json.dumps(res,indent=1)import loggingfrom logging.handlers import RoingFileHandlerimport datetime# pr(datetime.datetime.now().strftime(%Y_%m_%d_%H_%M_%S)STYLE = fore:# 前景色black: 30,# 黑色red: 31,# 红色green: 32,# 绿色yellow: 33,# 黄色blue: 34,# 蓝色purple: 35,# 紫红色cyan: 36,# 青

7、, fore = , back = ):mode = %s % STYLEmodemode if STYLEmode.get(mode) elsefore = %s % STYLEforefore if STYLEfore.get(fore) elseback = %s % STYLEbackback if STYLEback.get(back) elsestyle = ;.join(s for s in mode, fore, back if s)style = 033%sm % style if style else end= 033%sm % STYLEdefaultend if sty

8、le else return %s%s%s % (style, string, end)debug：最细微的信息到 debug 中，这个级别就是用来 debug 的，看程序在哪一次迭发生了错误，比如每次循环都输出一些东西用 debug 级别info：级别用于 routines，也就是输出 start finish 状态改变等信息warn：输出一些相对重要，但是不是程序 bug 的信息，比如输入了错误的，或者连接较慢error：输出程序 bug，打印异常信息critical：用于处理一些非常糟糕的事情，比如内存溢出、磁盘已满，这个一般较少使用class Logger:def init (self

9、,inLevel=DEBUG,inName= name ):self.logger = logging.getLogger(inName)self.logger.setLevel(inLevel)self.formatter = logging.Formatter(%(asctime)s - %(name)s- %(levelname)s - %(message)s)def addHand(self,source):self.logger.addHandler(source)def debug(self, msg):self.logger.debug(msg)def info(self, ms
