Question

这是我的代码，为什么它对我不起作用？它询问了问题，但错过了我创建的if语句。

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。如果您想使用此方法，我建议您执行以下操作：

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

elif ...

此外，您只需要执行一次导入，因此只有一行说import time会这样做;）

Answer 2

除了MrHug发现的关键错误之外，您的代码还存在以下问题：

大量不必要的重复;
错误使用import;
大量不必要的重复;
对字符串格式化的一种坦率的令人困惑的尝试;和
大量不必要的重复。

请注意，以下代码执行您尝试执行的操作，但采用更合理的方式：

# 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)

您可以进一步将最小信息（即两个数字和运算符）存储在ques列表中，然后格式化问题并计算代码本身的输出。
