How do you get a section's ID I need to access just the ID of a specific section.

I do that like this and it works:

{% set enroll = craft.sections.getSectionByHandle('workshopEnrollments') %}


But when I do:

{% for e in enroll %} {{ e.sectionId }} {% endfor %}


or:

{% for e in enroll %} {{ e.id }} {% endfor %}


I get the error:

Impossible to access an attribute ("sectionId") on a string variable ("32")


However, when I view the variable inside my form what I actually see is exactly this 

32Workshop EnrollmentsworkshopEnrollmentschannel1workshop-enrollments/_entry1


So my question is, how can I just display the id.  Both ".id" and ".sectionId" produce the same error mentioned above.  

"32" is the id I want so it is the correct return, but this seems to show everything about it in a string and I need just the id. I am using getSectionByHandle because I have no other data to use in this particular view.

Thanks for any help.
getSectionByHandle doesn't return an array, but a single SectionModel - so you need to remove the for loop:

{% set enroll = craft.sections.getSectionByHandle('workshopEnrollments') %}

{{ enroll.id }}
