payload = { 'username':'xxxxx',
            'passwd':'xxxx'}
session = requests.Session()
req = session.post('https://exemple.com/0',data=payload)

payload ={'check_type_diff':'0',
          'category':'19',
          'company_ad':'0'}


req = session.post('https://exemple.com/0', data=payload )
print req.content

Note: You should use post('URL',files=files) if you have file content. The multipart data just works as a normal data, just the formatting and the method is not the same.

Example: If you have a file and some multipart data, your code will be like this:

files = {"file":(filename1,open(location+'/'+filename,"rb"),'application-type')}
payload ={'file-name':'Filename',
          'category':'19'}


req = session.post('https://exemple.com/0', data=payload, file=files)
print req.content

You don't even need to add the line "file" into the payload, the requests will put the request together.
