title: SyntaxError: f-string expression part cannot include a backslash
body: <p>I have this api call.</p>
  <pre><code>payload = &quot;{\\&quot;weight\\&quot;:{\\&quot;value\\&quot;:\\&quot;85.00\\&quot;,\\&quot;unit\&quot;:\\&quot;kg\\&quot;},\\&quot;height\\&quot;:{\\&quot;value\\&quot;:\\&quot;170.00\\&quot;,\\&quot;unit\\&quot;:\\&quot;cm\\&quot;},\\&quot;sex\\&quot;:\\&quot;m\\&quot;,\\&quot;age\\&quot;:\\&quot;24\\&quot;,\\&quot;waist\\&quot;:\\&quot;34.00\\&quot;,\\&quot;hip\\&quot;:\\&quot;40.00\\&quot;}&quot;
  </code></pre>
  <p>I want to use a f string to change those values but I get a syntax error saying I can't use backslash for f strings. What can I do?</p>
