python實戰，用戶答題分享給大家。

主要包含內容，文件的讀取，更改，保存。不同文件夾引入模塊。輸入，輸出操作。隨機獲取數據操作

隨機生成算數表達式，用戶輸入答案，正確記錄分數，錯誤返回0，并把用戶分數記錄到文本文件中，如用戶名不存在著新建用戶

myPythonFunction.py包含三個函數

#coding=utf-8 from random import randint from os import remove,rename  #function 輸入用戶名字，獲得用戶得分，返回得分或者-1 def getUserScore(userName):  try:   f = open("userScores.txt","r")   msg = f.readline()   score=-1;   while len(msg):    msg = msg.strip('/n')    msgArr = msg.split(",")    if(msgArr[0]==userName):     score = msgArr[1]     break    msg = f.readline()   f.close()   return score  except IOError:   f=open("userScores.txt","w")   f.close()    return -1  #function 更新或者保存用戶名字，用戶得分 def updateUserPoints(userName,score):  temp = getUserScore(userName)  if(temp==-1):   f = open("userScores.txt","a")   msg = userName+","+str(score)+"/n"   f.write(msg)   f.close()  else:   temp = open("userScores.tmp","w")   f = open("userScores.txt","r")   msg = f.readline()   while len(msg):    msg = msg.strip('/n')    msgArr = msg.split(",")    if(msgArr[0]==userName):     msgArr[1] = str(score)    temp.write(msgArr[0]+","+msgArr[1]+"/n")     msg = f.readline()   f.close()   temp.close()   remove("userScores.txt")   rename("userScores.tmp","userScores.txt")  #function 獲取隨機生成的數學表達式 ，返回字符串   def getQuestionString():  operandList = []  operatorList = []  operatorDict=("+","-","*","**")  questionString = ''  for i in range(5):   operandList.append(randint(1,9))  for j in range(4):   operatorList.append(operatorDict[randint(0,3)])  for k in range(4):   questionString += str(operandList[k])+operatorList[k]  questionString +=str(operandList[4])  return questionString 

mathGame.py作為主函數

# -*- coding:utf-8 -*- import sys if 'H://python/func' not in sys.path:  sys.path.append('H://python//func') import myPythonFunction as myfunc   print("請輸入你的名字：") use = input() use=use.strip("/n") count = 0 if(myfunc.getUserScore(use)==-1):  print("你是個新用戶！")  myfunc.updateUserPoints(use,0) else:  count = int(myfunc.getUserScore(use))  print("你當前分數為：",count)  while(1):  questionString=myfunc.getQuestionString()  result = eval(questionString)  print("問題：",questionString.replace("**","^"))  print("請輸入你的答案：")  userResult = input()  userResult = userResult.strip("/n")  flag = True  if(userResult.startswith("-")):   userResult = userResult[1:]   flag = False  while((not userResult.isdigit()) and userResult!="exit"):   print("請輸入數字，你的答案：")   userResult = input()   userResult = userResult.strip("/n")   if(userResult.startswith("-")):    userResult = userResult[1:]    flag = False  if(not flag):    userResult = "-"+userResult  if(userResult==str(result)):   print(1)   count = count+1  elif("exit"==userResult):   break   else:   print(0) myfunc.updateUserPoints(use,count) print("你當前分數為：",count) print("謝謝進入，歡迎下次再來！")
