Python flask how to display list of items in html template

i am following flask template to display a list of items in my html template but the for loop only displaying last value {'reference': 'Customer/bJxi0A3', 'display': 'TEST, Beacon'} from the list below can't understand why ?

{'reference': 'Customer/uH50Lnw3', 'display': 'DEFVERIFYTESTONE, Awiltthirtyfive'}
{'reference': 'Customer/eereURJQ3', 'display': 'FITTESTTWO, Abcnsixteen'}
{'reference': 'Customer/URJQ3', 'display': 'FITTESTTWO, Abcnsixteen'}
{'reference': 'Customer/bJxi0A3', 'display': 'TEST, Beacon'}

What do i need to do with this for loop to display all the values ?

{% for item, value in customer.items(): %}
     <tr>
       <td>{{ item }}</td>
         <td>{{ value }}</td>
     </tr>
     {% endfor %}

You need to create another for loop, that goes through the list of all dicts. For example:

dict_list = [{'reference': 'Customer/uH50Lnw3', 'display': 'DEFVERIFYTESTONE, Awiltthirtyfive'},
{'reference': 'Customer/eereURJQ3', 'display': 'FITTESTTWO, Abcnsixteen'},
{'reference': 'Customer/URJQ3', 'display': 'FITTESTTWO, Abcnsixteen'},
{'reference': 'Customer/bJxi0A3', 'display': 'TEST, Beacon'}]

{% for i in dict_list: %}
{% for item, value in i.items(): %}
     <tr>
       <td>{{ item }}</td>
         <td>{{ value }}</td>
     </tr>
     {% endfor %}
{% endfor %}
