Describe the bug
Content-Type is mandate while sending POST request for image upload. Content-Type is missing while generating Python Requests code using Postman code generator. E.g. 'image/png' hs to be included for uploading PNG files.

To Reproduce
In Body, set form-data.
Set KEY as 'upload' (note that this is not relevernt to the issue. I am just trying to match the screenshot.). Choose File from the dropdown(default is Text)
Set value - choose a png image from you computer.
Genererate Python Requests code.
Try executing the python code. We get error as invalid PNG file.

Expected code snippet and corresponding request
Expected-
files = [('upload', ('png_image.png', open('png_image.png', 'rb'), 'image/png'))]
Current -
files = [
('upload', open('/C:/fileupload/png_image.png','rb'))
]
