How to send a “multipart/form-data” with requests in python?

Question

How to send a multipart/form-data with requests in python? How to send a file, I understand, but how to send the form data by this method can not understand.

Answer 1

Here is the simple code snippet to upload a single file with additional parameters using requests:

url = 'https://'
fp = '/Users/jainik/Desktop/data.csv'

files = {'file': open(fp, 'rb')}
payload = {'file_id': '1234'}

response = requests.put(url, files=files, data=payload, verify=False)

Please note that you don't need to explicitly specify any content type.
