如何修复这个“幽灵”Bug？

Question

我知道如何正常打印嵌入，但这次很混乱。我甚至努力在不同的if语句中创建每个单独的嵌入

代码：

 
@client.command()
async def quizintsci(ctx,*, unit):
  unit = int(unit)
  if unit == 1:
    answer = ""
    wrongAnswer1 = ""
    wrongAnswer2 = ""
    obvWrongAnswer = ""
    questions1=["Which of these observations are qualitative observations?","I","FairOPShotgun","FairOPBot","She","He","No_lucas"]
    answerToExpect = ""
    questionNum = random.randint(0,len(questions1)-1)
    questionToAsk = questions1[questionNum]
    if questionNum == 0:

      correctAnswer = ["Luster", "Color", "Brightness", "Smoothness"]
      wrongAnswer = ["Time", "Price", "Height", "Weight", "Volume", "Density", "Percentage", "Ratio", "Money", "Statistics", "John weighs 90 pounds", "The volume of a sphere is 200cm^3", "There are 100 people living in this town", "Each class has 16 students", "Age", "Temperature"]
      obviouslyWrongAnswers = ["Dog", "X+Y=13", "I have a pencil case", "The camera took a picture", "I love english class", "Popcorn", "Microphone"]
      answer = correctAnswer[random.randint(0, len(correctAnswer) -1)]
      wrongAnswer1 = wrongAnswer[random.randint(0, len(wrongAnswer) -1)]
      wrongAnswer2 = wrongAnswer[random.randint(0, len(wrongAnswer) -1)]
      obvWrongAnswer = obviouslyWrongAnswers[random.randint(0, len(obviouslyWrongAnswers) -1)]
    randomNum = random.randint(0, 3)
    if randomNum == 0:
      embedQuiz = discord.Embed(title="", description="", color=0xFFFFFF)
      embedQuiz.set_author(name="Science Question", url= "https://youtube.com/fairopshotgun",icon_url="https://cdn.discordapp.com/emojis/859474000145154098.png?v=1")
      embedQuiz.add_field(name = questionToAsk, value = "** **", inline = True)
      embedQuiz.add_field(name = "A: ", value = answer, inline = False)
      embedQuiz.add_field(name = "B: ", value = wrongAnswer1, inline = True)
      embedQuiz.add_field(name = "C: ", value = wrongAnswer2, inline = False)
      embedQuiz.add_field(name = "D: ", value = obvWrongAnswer, inline = True)
      embedQuiz.set_footer(text='https://youtube.com/fairopshotgun',icon_url="https://media.discordapp.net/attachments/861325953191116813/895753939276931082/download.jpeg")
      await ctx.reply(embed = embedQuiz, mention_author = False)
      answerToExpect = "A"
    elif randomNum == 1:
      embedQuiz = discord.Embed(title="", description="", color=0xFFFFFF)
      embedQuiz.set_author(name="Science Question", url= "https://youtube.com/fairopshotgun",icon_url="https://cdn.discordapp.com/emojis/859474000145154098.png?v=1")
      embedQuiz.add_field(name = questionToAsk, value = "** **", inline = True)
      embedQuiz.add_field(name = "A: ", value = wrongAnswer1, inline = False)
      embedQuiz.add_field(name = "B: ", value = answer, inline = True)
      embedQuiz.add_field(name = "C: ", value = wrongAnswer2, inline = False)
      embedQuiz.add_field(name = "D: ", value = obvWrongAnswer, inline = True)
      embedQuiz.set_footer(text='https://youtube.com/fairopshotgun',icon_url="https://media.discordapp.net/attachments/861325953191116813/895753939276931082/download.jpeg")
      await ctx.reply(embed = embedQuiz, mention_author = False)
      answerToExpect = "B"
    elif randomNum == 2:
      embedQuiz = discord.Embed(title="", description="", color=0xFFFFFF)
      embedQuiz.set_author(name="Science Question", url= "https://youtube.com/fairopshotgun",icon_url="https://cdn.discordapp.com/emojis/859474000145154098.png?v=1")
      embedQuiz.add_field(name = questionToAsk, value = "** **", inline = True)
      embedQuiz.add_field(name = "A: ", value = wrongAnswer1, inline = False)
      embedQuiz.add_field(name = "B: ", value = wrongAnswer2, inline = True)
      embedQuiz.add_field(name = "C: ", value = answer, inline = False)
      embedQuiz.add_field(name = "D: ", value = obvWrongAnswer, inline = True)
      embedQuiz.set_footer(text='https://youtube.com/fairopshotgun',icon_url="https://media.discordapp.net/attachments/861325953191116813/895753939276931082/download.jpeg")
      await ctx.reply(embed = embedQuiz, mention_author = False)
      answerToExpect = "C"
    elif randomNum == 3:
      embedQuiz = discord.Embed(title="", description="", color=0xFFFFFF)
      embedQuiz.set_author(name="Science Question", url= "https://youtube.com/fairopshotgun",icon_url="https://cdn.discordapp.com/emojis/859474000145154098.png?v=1")
      embedQuiz.add_field(name = questionToAsk, value = "** **", inline = True)
      embedQuiz.add_field(name = "A: ", value = wrongAnswer1, inline = False)
      embedQuiz.add_field(name = "B: ", value = wrongAnswer2, inline = True)
      embedQuiz.add_field(name = "C: ", value = obvWrongAnswer, inline = False)
      embedQuiz.add_field(name = "D: ", value = answer, inline = True)
      embedQuiz.set_footer(text='https://youtube.com/fairopshotgun',icon_url="https://media.discordapp.net/attachments/861325953191116813/895753939276931082/download.jpeg")
      await ctx.reply(embed = embedQuiz, mention_author = False)
      answerToExpect = "D"
    userInput = await client.wait_for("message")
    if str(userInput.content) == answerToExpect:
      await ctx.send("NO WAY! You got the question correct, " + ctx.message.author.display_name + "!")
      
    else:
      await ctx.send("RIP!! "+ ctx.message.author.display_name+ ", you got the question wrong! The correct answer was *" + str(answer) + "*.")
   

当我使用命令时，它不会显示任何内容。我得到一个错误

错误：

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

为什么会这样？很明显，我为每个嵌入设置了值，所以我不知道为什么它会说该字段是必需的

Answer 1

只有当变量questionNum为0时，才能定义答案。因此，当questionNum不是0时，嵌入字段都是空的

我不是很确定最终结果应该是什么样子，但是您可以从randomNum = random.randint(0, 3)行开始缩进所有内容，以仅在questionNum为0时使用这些答案，或者您可以从if questionNum == 0:块中取出定义答案的随机逻辑。任何一个都应该有效
