Question

有谁知道如何使下面的代码工作？我希望程序从我的问题列表中随机选择一个问题，直到我遇到5个问题。代码随机选择1个问题，但不重复。

import random
name=input("What is your name?")
score = 0
qno = 0

questionlist = ["1+3", "4-1", "3*3", "5+5", "10*3", "10-4"]

while qno < 10:
    qno = qno+1
question = random.choice(questionlist)
print (question)
answer = int (input("what is the answer"))
if answer ==eval(question):
    print("correct")
    score = score+1
else:
    print("incorrect")

Answer 1

您的代码仅循环遍历while循环的第一个语句。 Python中的缩进用于定义属于你的while，if，for等语句的代码。

以下功能齐全的代码;

import random
name=input("What is your name?")
score = 0
qno = 0

questionlist = ["1+3", "4-1", "3*3", "5+5", "10*3", "10-4"]

while qno < 5:
    qno = qno+1
    question = random.choice(questionlist)

    print (question)
    answer = int (input("what is the answer"))

    if answer==eval(question):
      print("correct")
      score = score+1
    else:
      print("incorrect")

Answer 2

你的while循环中唯一的东西就是增加qno的命令，这将使循环停止，但不是很多。

Python - 在while循环中列出
