First: anything that comes from the outside world should not be trusted initially. Malicious users can enter all sorts of exploits through a form that can undermine the security of your site. So, any form data must be sanitized before you use them.

Secondly: the field values in request.POST or request.GET are just strings. Even if your form field can be defined as an integer (say, age) or date (say, birthday), the browser would send them as strings to your view. Invariably, you would like to convert them to the appropriate Python types before use. The form class does this conversion automatically for you while cleaning.

CSRF_Token is the security mechanism against Cross-Site Request Forgery (CSRF) attacks for your forms. It works by injecting a server-generated random string called a CSRF token, unique to a user's session. Every time a form is submitted, it must have a hidden field that contains this token. This token ensures that the form was generated for user by the original site, rather than a fake form created by an attacker with similar fields.
