title: parse multipart/form-data, received from requests post
body: <p>I am writing Web Service Client, using requests library. I am getting data in multipart/form-data that contains a file and text-json. I have no idea how to parse it. Is there a proper library to parse multipart/form-data format in python or should I write parser on my own? </p>
  
  <p>my code:</p>
  
  <pre><code>data = {
    "prototypeModel" :('prototypeModel', open(prototypeModel, 'rb'), 'application/octet-stream', {'Expires': '0'}),
    "mfcc_1" : ('mfcc', open(mfcc_1, 'rb'), 'application/octet-stream', {'Expires': '0'}),
    "mfcc_2" : ('mfcc', open(mfcc_2, 'rb'), 'application/octet-stream', {'Expires': '0'}),
    "mfcc_3" : ('mfcc', open(mfcc_3, 'rb'), 'application/octet-stream', {'Expires': '0'}),
  }
  
  print( '---------------------- start enroll ----------------------')
  testEnrollResponse = requests.post(server+sessionID, files = data, json = declaredParameters)
  </code></pre>
