Module not found Error: forms wtforms

I'm learning Flask, making a form with wtforms , but by doing:

import forms

in my views.py file, where are the routes, I get it:

  

"ModuleNotFoundError: no module named 'forms'",

and the forms.py file are in the same directory as views.py.

The import header of forms.py contains:

from wtforms import Form               
from wtforms import StringField, TextField                                         
from wtforms.fields.html5 import EmailField

class CommentForm(Form):
    ........

The views.py file contains:

 from flask import request, redirect, render_template, url_for
 from app import app
 import forms

  .........

P.D: I would put the files in external links, but I do not have permission to put many links yet.
