Accessing variables using a for loop in HTML (python flask)

Question

class fruit(flaskform):
fruit1 = "apple"
fruit2 = "orange"
fruit3 = "grapes"

I am trying to access the variables in a for loop in my html page.

{% for index in range(3) %}
    {{"fruit" + index}}
{%endfor%}

Is this possible? I would like to avoid writing 100 lines of code to access the variables if I have 100 fruits. I am new to flask and html. My question could be unclear and feel free to ask me if more info is needed.

class fruit(flaskform): fruit = ["apple", "orange", "graps"] in HTML: {% for index in range(3) %} {{"fruit" + index}} {%endfor%} Like this? — calvert

You can store your fruits in a list like this:

fruits = ['apple', 'orange', 'grapes']

Then, you can use a for loop in Jinja2 to iterate through your list and display each individual item.

{% for fruit in fruits %}
    {{ fruit }}
{% endfor %}
