Avatar命令在用户是角色不一致时出错.py

Question

我正在制作一个avatar命令，该命令有效，但我不知道如何在成员是角色或成员不是成员时出错。谢谢

我的代码：

@client.command(aliases=["av","useravatar","usericon","userav","icon"])
async def avatar(ctx, *,  avamember : discord.Member=None):
try:
if avamember == None:
Author = ctx.author
userAvatarUrl = Author.avatar_url
stringUrl = str(userAvatarUrl)
png = stringUrl.replace("webp","png")
jpg = stringUrl.replace("webp","jpg")
embed = discord.Embed(title = f"{Author}'s avatar.",
description = f"**Links :** n[Default]({userAvatarUrl}) n[PNG]({png}) n[JPG]({jpg})",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)

now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by  {ctx.author} at {current_time}")
await ctx.reply(embed=embed, mention_author=False)
else:
userAvatarUrl = avamember.avatar_url
stringUrl = str(userAvatarUrl)
png = stringUrl.replace("webp","png")
jpg = stringUrl.replace("webp","jpg")
embed = discord.Embed(title = f"{avamember}'s avatar.",
description = f"**Links :** n[Default]({userAvatarUrl}) n[PNG]({png}) n[JPG]({jpg})",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by  {ctx.author} at {current_time}")
await ctx.reply(embed=embed,mention_author=False)
except:
embed = discord.Embed(title = f"ERROR!",
description = f"An error acurred, please try again.",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by  {ctx.author} at {current_time}")
await ctx.reply(embed=embed,mention_author=False)

我得到的错误：

您可以执行if语句来检查成员是否在服务器中。

@client.command(aliases=["av","useravatar","usericon","userav","icon"])
async def avatar(ctx, *,  avamember : discord.Member=None):
if avamember in ctx.guild:
try:
if avamember == None:
Author = ctx.author
userAvatarUrl = Author.avatar_url
stringUrl = str(userAvatarUrl)
png = stringUrl.replace("webp","png")
jpg = stringUrl.replace("webp","jpg")
embed = discord.Embed(title = f"{Author}'s avatar.",
description = f"**Links :** n[Default]({userAvatarUrl}) n[PNG]({png}) n[JPG]({jpg})",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)

now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by  {ctx.author} at {current_time}")
await ctx.reply(embed=embed, mention_author=False)
else:
userAvatarUrl = avamember.avatar_url
stringUrl = str(userAvatarUrl)
png = stringUrl.replace("webp","png")
jpg = stringUrl.replace("webp","jpg")
embed = discord.Embed(title = f"{avamember}'s avatar.",
description = f"**Links :** n[Default]({userAvatarUrl}) n[PNG]({png}) n[JPG]({jpg})",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by  {ctx.author} at {current_time}")
await ctx.reply(embed=embed,mention_author=False)
except:
embed = discord.Embed(title = f"ERROR!",
description = f"An error acurred, please try again.",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by  {ctx.author} at {current_time}")
await ctx.reply(embed=embed,mention_author=False)
else:
return await ctx.send("That member is not valid!")
