title: how can get requests from wolfram (discord.py)
body: <p>I've tried multiple solutions but i can't figure out what's wrong</p>
  <p>my code:</p>
  <pre><code>    @commands.command(pass_context=True)
      async def ask(self, ctx, *, s: str):
          s.replace(' ', '+')
          req = requests.get(&quot;http://api.wolframalpha.com/v1/result?appid=RPYQ54-Q3W9QJKWR9&amp;i=&quot; + s)
          author = ctx.message.author
          em = (author, req.text)
          await ctx.send(embed=em)
  </code></pre>
  <p>my error:</p>
  <pre><code>    raise CommandInvokeError(exc) from exc
  discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'tuple' object has no attribute 'to_dict'
  </code></pre>
