Question

因此，我正在执行whois命令，而我正在执行的if语句将其执行，以便如果用户没有角色，则value = None。但是，我有麻烦。这是代码

  @commands.command(aliases=["whois"])
  async def userinfo(self, ctx, member: discord.Member = None):
      if not member: 
        member = ctx.message.author
      embed = discord.Embed(colour=discord.Colour(random.randint(1, 16777215)), timestamp=ctx.message.created_at,title=f"User Info - {member}")
      embed.set_thumbnail(url=member.avatar_url)
      embed.add_field(name="Name", value=member.name)
      embed.add_field(name="ID:", value=member.id)
      embed.add_field(name="Nickname:", value=member.display_name)
      embed.add_field(name="Status", value=member.status)
      embed.add_field(name="Created Account On:", value=member.created_at.strftime("%a, %#d %B %Y, %I:%M  UTC"))
      embed.add_field(name="Joined Server On:", value=(member.joined_at.strftime("%a, %#d %B %Y, %I:%M %p UTC")))
      roles = [role.mention for role in member.roles[1:]]
      embed.add_field(name=f"Roles({len(roles)}):",value=",".join(roles), 
      inline=False)
      embed.add_field(name="Highest Role:", value=member.top_role.mention)
      await ctx.send(embed=embed)
      if roles == None: 
        embed.add_field(name="Roles", value="None", inline=False)

所以我问我的朋友，谁是python的佼佼者，他就把这个发给我：

  @commands.command(aliases=["whois"])
  async def userinfo(self, ctx, member: discord.Member = None):
      if not member: 
        member = ctx.message.author
      embed = discord.Embed(colour=discord.Colour(random.randint(1, 16777215)), timestamp=ctx.message.created_at,title=f"User Info - {member}")
      embed.set_thumbnail(url=member.avatar_url)
      embed.add_field(name="Name", value=member.name)
      embed.add_field(name="ID:", value=member.id)
      embed.add_field(name="Nickname:", value=member.display_name)
      embed.add_field(name="Status", value=member.status)
      embed.add_field(name="Created Account On:", value=member.created_at.strftime("%a, %#d %B %Y, %I:%M  UTC"))
      embed.add_field(name="Joined Server On:", value=(member.joined_at.strftime("%a, %#d %B %Y, %I:%M %p UTC")))
      roles = [role.mention for role in member.roles[1:]]
      if roles == None:    embed.add_field(name=f"Roles({len(roles)}):",value=",".join(roles), inline=False)
      embed.add_field(name="Highest Role:", value=member.top_role.mention)
      await ctx.send(embed=embed)

这是错误

In embed.fields.6.value: This field is required

它可以工作，但是问题在于它显示了@@ everyone角色，我如何摆脱@@ everyone角色？

Answer 1

这是固定的代码，@everyone角色始终是成员的第一个角色，因此只需尝试访问第二个元素member.roles[1:]中的列表即可将其排除，嵌入，但用户除@everyone角色外没有其他任何角色，因为roles列表为空，因此会吐出一个错误，因此您必须进行检查以防止插入空值。

commands.command(aliases=["whois"])
async def userinfo(self, ctx, member: discord.Member = None):
    if not member: 
        member = ctx.message.author
    embed = discord.Embed(colour=discord.Colour(random.randint(1, 16777215)), timestamp=ctx.message.created_at,title=f"User Info - {member}")
    embed.set_thumbnail(url=member.avatar_url)
    embed.add_field(name="Name", value=member.name)
    embed.add_field(name="ID:", value=member.id)
    embed.add_field(name="Nickname:", value=member.display_name)
    embed.add_field(name="Status", value=member.status)
    embed.add_field(name="Created Account On:", value=member.created_at.strftime("%a, %#d %B %Y, %I:%M  UTC"))
    embed.add_field(name="Joined Server On:", value=(member.joined_at.strftime("%a, %#d %B %Y, %I:%M %p UTC")))

    # Fixed part
    roles = [role.mention for role in member.roles[1:]]

    if len(member.roles[1:]) < 1:
        embed.add_field(name=f"Roles:",value="None", inline=False)
        embed.add_field(name="Highest Role:", value="None")
    elif roles != None:
        embed.add_field(name=f"Roles({len(roles)}):",value=",".join(roles), inline=False)
        embed.add_field(name="Highest Role:", value=member.top_role.mention)
    # End of fix
    
    await ctx.send(embed=embed)

我的if语句在我的whois命令中不起作用|不和谐
