[Fixed]-How can submit form with array fields and process on view?

Actually what is posted to you is ans0, ans1, ..., ansN.
So what you want to do is something like this:

answer_fields = [field for field in request.POST if field.startswith('ans')]
for field in answer_fields:
    # Do something with `field`...
    print(request.GET[field])

Additionally, you might want to check that the latter part is numeric, like so:

[field for field in request.POST
 if field.startswith('ans') and field[3:].isnumeric()]
