How to convert between Clojure maps and Python dictionaries?

[wjke-nics]

I'm trying to work with both Clojure maps and Python dictionaries in my Basilisp code. Could you please provide examples of:

1. Converting a Clojure persistent map to a Python dict
2. Converting a Python dict back to a Clojure persistent map

A simple code example showing both conversions would be very helpful. Thanks!

Hi @wjke-nics,

You can use the lisp->python to recursively convert Basilisp data structures into Python data structures,. These includes converting keyword keys into strings by default:

basilisp.user=> (lisp->py {:ten {:eleven 11}})
#py {"ten" #py {"eleven" 11}}

Use the py->lisp to recursively convert Python data structures into Basilisp data structures. These includes converting string keys into keywords by default:

basilisp.user=> (py->lisp #py {"twelve" #py {"thirteen" 13}})
{:twelve {:thirteen 13}}

In addition

You can use the #py {...} reader macro to define a Python Dictionary in Basilisp (see Data Readers):

basilisp.user=> #py {"six" 6}
#py {"six" 6}

Use the python/dict function to convert a Basilisp map into a Python dictionary:

basilisp.user=> (python/dict {"seven" 7})
#py {"seven" 7}

I hope this helps!
