python实现用户答题功能

python实战，用户答题分享给大家。

主要包含内容，文件的读取，更改，保存。不同文件夹引入模块。输入，输出操作。随机获取数据操作

随机生成算数表达式，用户输入答案，正确记录分数，错误返回0，并把用户分数记录到文本文件中，如用户名不存在着新建用户

myPythonFunction.py包含三个函数

#coding=utf-8 from random import randint from os import remove,rename  #function 输入用户名字，获得用户得分，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 更新或者保存用户名字，用户得分 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 获取随机生成的数学表达式 ，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作为主函数

# -*- coding:utf-8 -*- import sys if 'H:\\python\func' not in sys.path:  sys.path.append('H:\\python\\func') import myPythonFunction as myfunc   print("请输入你的名字：") use = input() use=use.strip("\n") count = 0 if(myfunc.getUserScore(use)==-1):  print("你是个新用户！")  myfunc.updateUserPoints(use,0) else:  count = int(myfunc.getUserScore(use))  print("你当前分数为：",count)  while(1):  questionString=myfunc.getQuestionString()  result = eval(questionString)  print("问题：",questionString.replace("**","^"))  print("请输入你的答案：")  userResult = input()  userResult = userResult.strip("\n")  flag = True  if(userResult.startswith("-")):   userResult = userResult[1:]   flag = False  while((not userResult.isdigit()) and userResult!="exit"):   print("请输入数字，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("你当前分数为：",count) print("谢谢进入，欢迎下次再来！") 

文件目录结构，将myPythonFunction.py放到func文件夹中。userScores.txt存放用户名和相应的得分
