需要关于随机答案的简单测验帮助

Question

这是我的代码，为什么它不适合我？它提出了问题，但错过了我创建的if声明。

print("What is your name?") 
name = input("") 

import time 
time.sleep(1) 

print("Hello", name,(",Welcome to my quiz")) 

import time 
time.sleep(1) 

import random 
ques = ['What is 2 times 2?', 'What is 10 times 7?', 'What is 6 times 2?'] 
print(random.choice(ques)) 

# Please note that these are nested IF statements 

if ques == ('What is 2 times 2?'): 
    print("What is the answer? ") 
    ans = input("") 


    if ans == '4': 
     print("Correct") 

    else: 
     print("Incorrect") 

elif ques == ('What is 10 times 7?'): 
    print("What is the answer? ") 
    ans = input("") 

    if ans == '70': 
     print("Correct") 

    else: 
     print("Incorrect") 

elif ques == ('What is 6 times 2?'): 
    print("What is the answer? ") 
    ans = input("") 

    if ans == '12': 
      print("Correct") 

    else: 
     print("Incorrect") 

import time 
time.sleep(1) 

import random 
ques = ['What is 55 take away 20?', 'What is 60 devided by 2?', 'What is 500 take away 200'] 
print(random.choice(ques)) 


if ques == ('What is 55 take away 20?'): 
    print("What is the answer? ") 
    ans = input("") 

    if ans == '35': 
     print("Correct") 

    else: 
     print("Incorrect") 

elif ques == ('What is 60 devided by 2?'): 
    print("What is the answer? ") 
    ans = input("") 

    if ans == '30': 
     print("Correct") 

    else: 
     print("Incorrect") 

elif ques == ('What is 500 take away 200'): 
    print("What is the answer? ") 
    ans = input("") 

    if ans == '300': 
     print("Correct") 

    else: 
     print("Incorrect") 

Answer 1

ques始终等于完整列表，而不是列表中的单个元素。 如果你想用这个方法，我建议做以下几点：

posedQuestion = random.choice(ques) 
print(posedQuestion) 
if posedQuestion == "First question": 

elif ... 

此外，你只需要做你的进口一次，所以只有一条线说import time做到;）

Answer 2

还有由MrHug确定的关键错误，您的代码存在以下问题：

1. 大量不必要的重复;
2. 错误地使用import;
3. 大量不必要的重复;
4. 字符串格式化的一个坦率扑朔迷离的尝试;和
5. 大量的不必要的重复。

注意，下面的代码做什么你正在尝试做的，但在一个更合乎逻辑的方式：

# import once, at the top 
import random 

# use functions to reduce duplication 
def ask_one(questions): 
    question, answer = random.choice(questions): 
    print(question) 
    if input("") == answer: 
     print("Correct") 
    else: 
     print("Incorrect") 

# use proper string formatting 
print("What is your name? ") 
name = input("") 
print("Hello {0}, welcome to my quiz".format(name)) 

# store related information together 
ques = [('What is 2 times 2?', '4'), 
     ('What is 10 times 7?', '70'), 
     ('What is 6 times 2?', '12')] 

ask_one(ques) 

你可以通过存储的最少信息（即两个数字和走得更远运算符）列在ques的列表中，然后格式化问题并计算代码本身的输出。
