Command for posting user's avatar

Question

@bot.command(aliases=['av'])
async def avatar(ctx, *,  avamember : discord.Member = None):
    userAvatarUrl = avamember.avatar_url
    await ctx.send(userAvatarUrl)

I would like the command to post the mentioned user's avatar. If no user is mentioned, it should post my own avatar.

As the previous answer says, you need to put an if statement if you didn't mention the user, but I updated the code to something good (like put it into an embed to make it more prettier):

@bot.command(aliases = ['av'])
async def avatar(ctx, member : discord.Member = None):
    if member == None:
        member = ctx.author # It will show your avatar if you didn't mention a user (if statement)
        embed = discord.Embed(title = f"{member.name}'s avatar", color = 0x2F3136)
        em.set_image(url = member.avatar_url) # Shows the avatar
        em.set_footer(text = f'Requested by {ctx.author}', icon_url = ctx.author.avatar_url)
        await ctx.send(embed = em)

Thank me later :D

You can check if member is None, then use the avatar of the ctx.author:

@bot.command(aliases=['av'])
async def avatar(ctx, *,  member : discord.Member = None):
if member == None:
    user_avatar_url = ctx.author.avatar_url
else: 
    user_avatar_url = member.avatar_url
await ctx.send(user_avatar_url)

@bot.command(aliases=["av"])
async def avatar(ctx, *, member: discord.Member = None):
    if member!=None:
        pfp = member.avatar_url
        embed = discord.Embed(title=f"{member.name}'s profile picture!")
        embed.set_image(url=pfp)
        await ctx.send(embed=embed)
    else:
        author = ctx.message.author
        pfp = author.avatar_url
        embed = discord.Embed(title=f"{author.name}'s profile picture!")
        embed.set_image(url=pfp)
        await ctx.send(embed=embed)
