title: Payload requests - string concatenate layout error
body: <p>I have code that reads a list of numbers that are parameters for a python order:</p>
  <pre><code>def search(number):
      url = &quot;http://localhost:8080/sistem/checkNumberStatus&quot;
      payload = '{\n\&quot;SessionName\&quot;:\&quot;POC\&quot;,\n\&quot;celFull\&quot;:\&quot;'+number+'\&quot;\n}'
      headers = {
      'Content-Type': 'application/json'
      }
  
      response = requests.request(&quot;POST&quot;, url, headers=headers, data = payload)
  
  object = open('numbers_wpp.txt', 'r')
  for numbers in object:
      search(number)
  </code></pre>
  <p>But, when I print the payload of my json the output is:</p>
  <pre><code>{
  &quot;SessionName&quot;:&quot;POC&quot;,
  &quot;celFull&quot;:&quot;5512997708936
  &quot;
  }
  {
  &quot;SessionName&quot;:&quot;POC&quot;,
  &quot;celFull&quot;:&quot;5512997709337
  &quot;
  }
  {
  &quot;SessionName&quot;:&quot;POC&quot;,
  &quot;celFull&quot;:&quot;5512992161195&quot;
  }
  </code></pre>
  <p>When reading the file with 3 numbers, the quotes in the <code>celFull</code> attribute closed correctly only in the last loop (last number), while the first two were broken into quotes. This break is giving error in queries.</p>
