title: Can't seem to retrieve stripe charge using python
body: <p>I have the following python code to create a charge in stripe.</p>
  
  <pre><code>a_charge = stripe.Charge.create(
  amount=cents, 
  currency="usd",
  source=token,
  description="my_description",
  application_fee=application_fee,
  stripe_account=teacher_stripe_id
  )
  </code></pre>
  
  <p>This succeeds (I think), because it shows up in my dashboard with a charge_id.
  But then, immediately after in the code, the following fails:</p>
  
  <pre><code>stripe.Charge.retrieve(a_charge.id)
  </code></pre>
  
  <p>With error:
      No such charge: somelongstringhere</p>
  
  <p>However, somelongstringhere is indeed the ID under charge details on my stripe dashboard.  So how come Stripe can't retrieve this charge?  Is this not the correct id?</p>
