Iterating through the form?

using the code exactly as its presented in the video, I'm running into a problem while iterating through the form. I think the problem is in the block of code below.

{% from 'macros.html' import render_field %} <form method="POST" action="" class="form"> {{ form.hidden_tag() }} {% for field in form %} {{ render_field(field) }} {% endfor %} <button type="submit" id="submit">Register!</button> </form>

If you check the element inspector in the browser, an extra (blank) field is created after all the form fields are iterated through and created. Its as if the for loop is executing one final time inexplicably. You cant see it in the browser rending because there's no formatting but if you try to add any CSS the problem becomes apparent. Whats going on here? Why is render_field() executing one extra time?
