title: How do I make an announcement command in Discord.py?
body: <p>No matter how hard I look I cannot find a tutorial on how to do this in Discord.py, It's all Discord.js. Here is my current code;</p>
  
  <pre><code>@bot.command(brief='announce [message]')
      async def announce(ctx, message : str):
              print(str(message))
              if(str(ctx.message.author) == user):
                      await ctx.send('User Authentication Successful')
                      try:
                              for chan in channels:
                                      try:
                                              channel = bot.get_channel(chan)
                                              info = discord.Embed(title='New Announcement!', description=str(message), color=0xFFFFFF)
                                              await channel.send(embed=info)
                                      except Exception as e:
                                              await ctx.send(e)
                                              await ctx.send("Error: " + str(chan))
                      except Exception as e:
                              await ctx.send(e)
  </code></pre>
  
  <p>And this is the error I am getting.</p>
  
  <pre><code>Ignoring exception in command announce

  <p>Please Help Me :(</p>
  
  <p>EDIT:  I'm sorry if anything was confusing. I'm trying to make an -announce command. Where I type -announce  and it announces (embedded) whatever was typed.</p>
