How to display array elements in python

Question

I'm trying to browse this array and display it on my django project but it doesn't work.

Views.py

def(request):
  
  {"product":[
    {
      "name":"sogi",
      "desc":"solo"
    },
    {
      "name":"molo",
      "desc":"kanta"
    },
  ]
 }
   context={"tab":"product"}
   return render(request,'api/myapi.html',context)

myapi.html

  {% for pro in tab %}
    {{pro.name}}
  {% endfor %}

you seem to be iterating the string "product" instead of the dictionary — Hedde van der Heide

def(request): tab = {"product":[ { "name":"sogi", "desc":"solo" }, { "name":"molo", "desc":"kanta" }, ] } context={"tab":tab} return render(request,'api/myapi.html',context) {% for pro in tab['product'] %} {{pro.name}} {% endfor %} — Deekshith Hari

You have to change your context creation:

def(request):
    tab = {"product": [...]}
    products = tab["products"]
    context = {"products": products}
    return render(request, "api/myapi.html", context)

And change usage in your template:

{% for product in products %}
    {% for key, value in product.items %}
        {{ key }}: {{ value }}<br>
    {% endfor %}
{% endfor %}

when I do {{ pro.name}} it doesn't show up ?

I've edited a bit my answer. Can you share what {{ pro }} returns to template?

Using your last answer I have : TypeError at /api/ string indices must be integers ! {% for pro in products %} {{ pro.name }} {{ pro.desc }} {% endfor %}

@Macba changed answer again, check it again. It's not that simple to retrieve dictionaries in templates after all.
