Correctly storing the list of items in db and then printing them item by item using jinja, flask and postgresql

Question

Newbie here. I have recently started learning coding and trying to build a webapp from scratch using Flask, Jinja and PostgreSQL.

I am using a multi-select input to store a list of strengths in a field that I want to later print item by item.

Strengths = ['Communication','Teamwork']

Here is what I have done: init.py

class Note(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    strengths = db.Column(db.String(10000))

form.html

<select
    class="form-select"
    id="strengths"
    name="strengths"
    multiple
    data-allow-clear="true"
    data-suggestions-threshold="0"
    data-show-all-suggestions="true"
  >
    <option disabled hidden value="">Choose a skill to endorse...</option>
    {% for skill in skills %}
    <option value="{{skill.label}}">{{skill.label}}</option>
    {% endfor %}
  </select>

views.py

strengths = request.form.getlist('strengths')
print(strengths)
new_note = Note(strengths=strengths)

The above print statement works fine and shows the outpur as expected ['Communication','Teamwork']

However, when I try to print this in jinja using {{Strengths}}, I see this as the output {Communication,Teamwork}

Checking the postgreSQL db, I see that the list is stored as printed by jinja {Communication,Teamwork}.

How can I make sure I can store the list in a way that I can print the first strength by using {{strengths[0]}}?

TIA
