How does Django handle form validation and processing?

Making the form validation easier: Django provides some specific mechanism in forms that is included in Django. In order to make forms, one has to define the form as a Python class, along with the specification of the fields and the rules regarding the validation. Django can also do all the other stuff for you-even the data validation at the time of form submission, to check whether your input is meeting the specified criteria or not. If the form is valid, it can process the data; otherwise, Django returns the form with error messages and allows users to make amends to their input. In this way, it makes sure that the data being used in your application is appropriately cleaned and reliable.
