課堂筆記隨記10-pycharm使用技巧v0

1、思路分解：1- 獲取文件中每一行的信息：學生 id 課程 id 簽到時間2- 按照要求去統(tǒng)計3- 輸出step over-單步運行每一行為一步def func():pr(1)pr(2)pr(3)pr(4)#1- 獲取文件中每一行的信息：學生 id 課程 id 簽到時間fileDir = rG:0005_1.txtdef putInfoToDict(fileName):resDict = #1- 打開文件with open(fileName) as fo:#2-所有行l(wèi)ines = fo.read().splitlines()#返回是 list#3- 對每一行進去提取數(shù)據(jù)-遍歷for line

2、in lines:# info = #臨時的字典line =line.replace(t,).replace(,).replace(),).replace(,)#切割 ,temp = line.split(,)checkTime = temp0lessonId =(temp1)userId =(temp2)#2- 按照要求去統(tǒng)計info = lessonid:lessonId, checkime:checkTime# infolessonid = lessonId# infocheckime = checkTimeif userId in resDict:#如果學生 id 在里面resDict

3、userId.append(info)else:#新增鍵值對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!)時間級別重要數(shù)據(jù)異常信息等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,# 紅色green: 32,# 綠色yellow: 33,# 黃色blue: 34,# 藍色purple: 35,# 紫紅色cyan: 36,# 青

6、藍色white: 37,# 白色,back :# 背景black: 40, # 黑色red: 41, # 紅色green: 42, # 綠色yellow: 43, # 黃色blue: 44, # 藍色purple: 45, # 紫紅色cyan: 46, # 青藍色white: 47, # 白色,mode :# 顯示模式mormal: 0,# 終端默認設(shè)置 bold: 1,#顯示 underline : 4,# 使用下劃線blink: 5,# 閃爍invert: 7,# 反白顯示hide: 8,# 不可見,default :end : 0,def UseStyle(string, mode =

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：最細微的信息到 debug 中，這個級別就是用來 debug 的，看程序在哪一次迭發(fā)生了錯誤，比如每次循環(huán)都輸出一些東西用 debug 級別info：級別用于 routines，也就是輸出 start finish 狀態(tài)改變等信息warn：輸出一些相對重要，但是不是程序 bug 的信息，比如輸入了錯誤的，或者連接較慢error：輸出程序 bug，打印異常信息critical：用于處理一些非常糟糕的事情，比如內(nèi)存溢出、磁盤已滿，這個一般較少使用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

10、g):(msg)def warning(self, msg):self.logger.warning(msg)def error(self, msg):self.logger.error(msg)#def critical(self, msg):self.logger.criticag)class FileLogger(Logger):#log 文件輸出類def init (self, logName):Logger. init (self, inLevel=DEBUG, inName= name )self.loggerName = logNameself.r

11、Handler =RoingFileHandler(_.log.format(self.loggerName,datetime.datetime.now().strftime(%Y_%m_%d_%H_%M_%S),maxBytes = 1*1024,backupCount =3,encoding=utf-8)self.rHandler.setFormatter(self.formatter)self.addHand(self.rHandler)class ConsoleLogger(Logger):#控制臺輸出日志類def init (self):Logger. init (self, inL

12、evel=DEBUG, inName= name )self.console = logging.StreamHandler()self.console.setFormatter(self.formatter)self.addHand(self.console)def debug(self, msg):self.logger.debug(UseStyle(msg, fore = black)#黑色def info(self, msg):(UseStyle(msg, fore = blue)#藍色def warning(self, msg):self.logger.warning(UseStyle(msg, fore = yellow)#黃色def error(self, msg):self.logger.error(UseStyle(msg, fore = red)#紅色def cr
