check variable type inside Jinja2 in Flask -

the template file created contains this:

{% if type({'a':1,'b':2}) dict %}     print "oh yes!!" {% else %}     print "oh no!!!" {% endif %} 

---

then jinja2 responds saying:

templateassertionerror: no test named 'dict' 

---

i new jinja2 , flask

you looking mapping test:

{% if {'a': 1, 'b': 2} mapping %}     "oh yes!" {% else %}     "oh no!" {% endif %} 

jinja not python though, don't have access builtins (type , print not exist, example, unless add them the context. in flask, context_processor decorator).

you don't need print @ all. default output (unless in child template extends parent, in case can interesting things null master fallback because blocks names available in master template output).
