title: Append function not working with no errors
body: <p>I'm making a car economy bot and lots of my friends were requesting unlimited car slots but when I use append nothing changes, it doesn't append &quot;new&quot; and it doesn't give an error.</p>
  <pre><code>if option == None and amount == None:
      for item in users[str(user.id)][&quot;cars&quot;]:
          em.add_field(name=f&quot;{index} . {item['car']}&quot;, value = f'.', inline = False)
  
      await ctx.send(embed = em)
      return
  
  if option == 'store' or option == 'park':
      new = {&quot;car&quot;: &quot;test again&quot;}
      users[str(user.id)][&quot;cars&quot;].append(new)
      await ctx.send('Done!')
  </code></pre>
  <p>This is my code the <code>option == None</code> part is to check the cars</p>
