{% set valuesCars = ['bmw', 'mercedes', 'seat', 'porsche', 'seat', 'bmw', 'seat'] %}
{% set valuesIntegers = [27, 32, 36, 36, 27, 32, 32] %}
{% set counts = {} %}
{# Change valuesCars to valuesIntegers to output the integers #}
{% for value in valuesCars %}
{% if counts[value] is not defined %}
{% set counts = counts|merge({ (value): 1 }) %}
{% else %}
{% set counts = counts|merge({ (value): counts[value] + 1 }) %}
{% endif %}
{% endfor %}
{% for key, count in counts %}
{{ key }}: {{ count }}
{% endfor %}
For valuesCars I get the correct output:
bmw: 2
mercedes: 1
seat: 3
porsche: 1
For valuesIntegers I don’t get the desired output. I get this:
0: 1
1: 1
2: 1
3: 1
4: 1
5: 1
6: 1
The desired output should be
27 : 2
32: 3
36 : 2
What am I’m missing here?

This is the solution:
Convert the numeric key value into a string key to avoid issues with numeric indices
{% set stringKey = 'value_' ~ value %}
This results in:
value_27
value_32
value_36
value_36
value_27
value_32
value_32
Check if the key exists and update its count, else set the count to 1
{% if attribute(valuesWithNewKey, stringKey) is defined %}
{% set valuesWithNewKey = valuesWithNewKey|merge({ (stringKey): valuesWithNewKey[stringKey] + 1 }) %}
{% else %}
{% set valuesWithNewKey = valuesWithNewKey|merge({ (stringKey): 1 }) %}
{% endif %}
Inside the for loop (value in valuesIntegers) when you print the stringKey and values you will get:
{% for value in valuesWithNewKey %}
{{ value }}<br>
{% endfor %}
value_27 : 1
value_32 : 1
value_32 : 1
value_36 : 1
value_36 : 1
value_36 : 1
value_36 : 1
value_36 : 1
value_36 : 2
value_27 : 2
value_27 : 1
value_27 : 2
value_32 : 2
value_32 : 2
value_32 : 2
value_32 : 2
value_32 : 3
value_32 : 2
Outside the for loop (value in valuesIntegers) after, replacing the ‘value_’ it will result in the desired output 🙏 💪 🏆
{% for stringKey, count in valuesWithNewKey %}
{{ stringKey|replace({'value_':''}) ~ ' : ' ~ count }}<br>
{% endfor %}
27 : 2
32 : 3
36 : 2
The whole code:
{% set valuesIntegers = [27, 32, 36, 36, 27, 32, 32] %}
{% set valuesWithNewKey = {} %}
{% for value in valuesIntegers %}
{% set stringKey = 'value_' ~ value %}
{% if attribute(valuesWithNewKey, stringKey) is defined %}
{% set valuesWithNewKey = valuesWithNewKey|merge({ (stringKey): valuesWithNewKey[stringKey] + 1 }) %}
{% else %}
{% set valuesWithNewKey = valuesWithNewKey|merge({ (stringKey): 1 }) %}
{% endif %}
{% endfor %}
{% for stringKey, count in valuesWithNewKey %}
{{ stringKey|replace({'value_':''}) ~ ' : ' ~ count }}<br>
{% endfor %}
used inside the set counts structure.
{% set valuesIntegers = [27, 32, 36, 36, 27, 32, 32] %}
{% set counts = {} %}
{% for value in valuesIntegers %}
{% if counts[value] is not defined %}
{% set counts = counts|merge({ (value): 1 }) %}
{% else %}
{% set counts = counts|merge({ (value): counts[value] + 1 }) %}
{% endif %}
{% endfor %}
{% for key, count in counts %}
{{ key }}: {{ count }}
