Create input mask for use in django forms

Good evening. I need to figure out how to apply masks in django's forms to a project, however, none of the previous attempts as successful. On the last test: from input_mask.widgets import InputMask However, perhaps for inexperience on my part, when using it not achieved in the desired result. What will be the mistake? Or in another case how do I use other alternatives to deal with this problem? Thank you very much in advance.
