Jinja2 - split string

I am trying to split out a shopping list string that looks like the following:

['Milk', 'Bread', 'sugar', 'rinse aid']

The string has 4 shopping list items, whereby I want to remove the [] at the front and the end, remove the '', and separate each item on a separate line if possible.

First I will presume that what you have is a list of items which you would like to show in a web page-

app.route('/myList')
def myList():
    list=['Milk', 'Bread', 'sugar', 'Colagate']
    return render_template('shoppingList.html',slist=list)

and in the shoppingList.html

{% for x in slist %}
 <div class="someClass">{{ x }}</div>
{% endfor %}

this should work for a list

If you have a string that looks like-

 listStr="['Milk', 'Bread', 'sugar', 'Colagate']"

what you can do is define-

 def listMaker(lst):
    listStr=listStr.replace(']','')
    listStr=listStr.replace('[','')
    listStr=listStr.replace(',','')
    listStr=listStr.replace('\'','')

    list=listStr.split(' ')
    return list

and then call this function-

app.route('/myList')
def myList():
    listStr="['Milk', 'Bread', 'sugar', 'Colagate']"
    list=listMaker(listStr)
    return render_template('shoppingList.html',slist=list)

the HTML code remains the same.

Your shopping list is not a string, its a list.

You can use for loop to iterate through each item and print it separately,

{% set shoppinglist = ['Milk', 'Bread', 'sugar', 'rinse aid'] %}

{%- for item in shoppinglist -%}
  {{ item }}
{% endfor %}

Output,

Milk
Bread
sugar
rinse·aid
