   The library `pretty-py3` is not actively maintained and I am not sure if we should use it that globally.
   
   Jinja uses built-in library not an external library - 
   https://github.com/pallets/jinja/blob/f009a004a2e70a3608d49aceb1814b90bb4370d6/src/jinja2/utils.py#L160
   
   https://docs.python.org/3.8/library/pprint.html
   
   That said -- I think the users who want it can use the library you mentioned or add their own custom filter.
   
   You can just do `{{ yourvar| custom_pprint}}` where `custom_pprint` is your custom filter and Jinja will print it nicely I think: https://stackoverflow.com/a/25728848/5691525
