I'm trying to do a info command as you can see but in the roles section, i can't display the user's roles. At first i did a working command but it display the "@everyone" role too, so i did a string for remove it (mention.remove("everyone")) but it doesn't work it gives an this error:

Command raised an exception: ValueError: list.remove(x): x not in list

我也尝试用“ @everyone”替换“ everyone”，但仍然无法正常工作。

@client.command()
async def info(ctx, user: discord.Member):

    mention = []
    for role in user.roles:
        mention.append(role.mention)
        mention.remove("everyone")

    b = ", ".join(mention)


    embed = discord.Embed(title="Info:", description=f"Info of: {user.mention}", color=discord.Color.orange())
    embed.add_field(name="Top role:", value=user.top_role)
    embed.add_field(name="Roles:", value=b)

    await ctx.send(embed=embed)

    You should simply use if to check value before you add to list - and then you don't need remove

    mention = []

for role in user.roles:
    if role.mention != "@everyone":
        mention.append(role.mention)

    与列表理解相同

    mention = [role.mention for role in user.roles if role.mention != "@everyone"]

    BTW: if you want to remove something then do it only once after for-loop and also use if to check if element exists

    mention = []

for role in user.roles:
    mention.append(role.mention)


if "@everyone" in mention:
    mention.remove("@everyone")
