title: Zapier Code Module Python input_data issue
body: <p>I am creating a api post request using fields from the zapier email parser and inserting them into the request using the Zapier code Python module. </p>
  
  <p>The problem is that I cant seem to get the input_data fields into the request. The request works correctly until I try inserting those fields.</p>
  
  <p>For example I have an input_data field named "first" for the "firstName" field and when I try to insert it into the data it breaks it, I have tried several different variations brackets, parantheses etc. </p>
  
  <p>I dont have a lot of python knowledge so I am pretty sure its a syntax issue. Hopefully someone can point me in the right direction. Here is the code with the "Api key etc removed" Thanks!</p>
  
  <pre><code> import requests
  
  
  'Api-Key': 'hidden',
  'Cache-Control': 'no-cache',
  'Content-Type': 'application/json', 
  
      }
  
      data = '{\n  "arrivalDate": "01/19/2021",  "departureDate": "01/25/2021",  "channelId": hidden,    "arrivalTime": "16:00",  "departureTime": "10:00",  "firstName": input_data("first"), "lastName": "Musetn",  "email": "test@gmail.com",  "phone": "0177123456789",  "notice": "Breakfast, one dog",  "adults": 1,  "priceStatus": 1,  "depositStatus": 1,  "language": "en"}'
  
      response = requests.post('https://login.smoobu.com/api/apartment/hidden/booking', headers=headers, data=data)
