title: Discord.py - SyntaxError f-string: empty expression not allowed
body: <p>I'm getting a SyntaxError: <code>f-string: empty expression not allowed</code> I'm not sure (at all) what this means</p>
  
  <p>I've tried moving around the code &amp; looked online but I've got no different results</p>
  
  <p>The code is:</p>
  
  <pre><code>@client.command()
  async def load(ctx, extension):
   client.load_extension(f'cogs.{extension}')
  
   await ctx.send(f"Loaded the {} module!".format(extension))
  </code></pre>
  
  <p>It's for cogs &amp; I'm sure I've got everything else right, I'm not sure though</p>
  
  <p>If anyone knows what to do then please tell me, thx</p>
