Question

我会承认我现在正在坚持学校项目。

我定义了为我生成随机数的函数，以及一个随机运算符（+， - 或*）。

我还定义了一个使用这些随机数显示问题的函数。

我创建了一个程序，它将生成并显示一个随机问题，并要求用户提供解决方案。如果用户是正确的，程序将打印“正确”，如果用户不正确，则相反。

我把所有这些放在一个循环中，使它重复10次。我的问题是我需要它来产生10个不同的问题，而不是第一次随机化10次的相同问题。

对于这种奇怪的措辞感到抱歉。

*我正在使用python，但我在这里使用CSS查看器显示代码，因为我无法让它显示任何其他方式。

谢谢。

import random

max = 10

def getOp(max): #generates a random number between 1 and 10
    randNum = random.randint(0,max)
    return randNum
randNum = getOp(max)


def getOperator(): #gets a random operator 
    opValue = random.randint(1,3)
    if opValue == 1:
        operator1 = '+'
    elif opValue == 2:
        operator1 = '-'
    elif opValue == 3:
        operator1 = '*'
    return operator1

operand1 = getOp(max)
operand2 = getOp(max)
operator = getOperator()

def doIt(operand1, operand2, operator): #does the problem so we can verify with user
    if operator == '+':
        answer = operand1 + operand2
    elif operator == '-':
        answer = operand1 - operand2
    elif operator == '*':
        answer = operand1 * operand2
    return answer
answer = doIt(operand1, operand2, operator)

def displayProblem(operand1, operand2, operator): #displays the problem
    print(operand1, operator, operand2, '=')


###My program:
for _ in range(10): #loops the program 10 times
    displayProblem(operand1, operand2, operator)

    userSolution = int(input('Please enter your solution: '))

    if userSolution == doIt(operand1, operand2, operator):
        print('Correct')

    elif userSolution != doIt(operand1, operand2, operator):
        print('Incorrect')

Answer 1

只需将生成随机值的代码移动到for循环中：

for _ in range(10): #loops the program 10 times

    randNum = getOp(max)                
    operand1 = getOp(max)
    operand2 = getOp(max)
    operator = getOperator()
    answer = doIt(operand1, operand2, operator)

    displayProblem(operand1, operand2, operator)

    userSolution = int(input('Please enter your solution: '))

    if userSolution == doIt(operand1, operand2, operator):
        print('Correct')

    elif userSolution != doIt(operand1, operand2, operator):
        print('Incorrect')

每当你要求用户输入时，就会调用它。

Answer 2

您生成问题，然后在循环中显示10次：

generateProblem()
for _ in range(10):
    showProblem()

当然你会得到10次同样的问题。要解决此问题，请在循环中生成问题：

for _ in range(10): generateProblem() showProblem()

Answer 3

破坏你的代码

import random

max = 10

def getOp(max): #generates a random number between 1 and 10
    randNum = random.randint(0,max)
    return randNum

def getOperator(): #gets a random operator 
    opValue = random.randint(1,3)
    if opValue == 1:
        operator1 = '+'
    elif opValue == 2:
        operator1 = '-'
    elif opValue == 3:
        operator1 = '*'
    return operator1

def doIt(operand1, operand2, operator): #does the problem so we can verify with user
    if operator == '+':
        answer = operand1 + operand2
    elif operator == '-':
        answer = operand1 - operand2
    elif operator == '*':
        answer = operand1 * operand2
    return answer

def displayProblem(operand1, operand2, operator): #displays the problem
    print(operand1, operator, operand2, '=')


###My program:
for _ in range(10): #loops the program 10 times
  operand1 = getOp(max)
  operand2 = getOp(max)
  operator = getOperator()
  displayProblem(operand1, operand2, operator)

  userSolution = int(input('Please enter your solution: '))

  if userSolution == doIt(operand1, operand2, operator):
    print('Correct')

  elif userSolution != doIt(operand1, operand2, operator):
    print('Incorrect')

如何获得随机/不同的东西，10次？
