Converting dict containing SymPy objects to JSON

[TARUN GABA]

Hi

I have a dict containing symbols as keys, mapped to float values. I need to convert it to JSON format(for passing to Javascript).

Here is an example dict:

constants = {l: 10.0, m: 10.0, g: 9.81}

python's json module cannot parse these symbols.What should be the best approach to implement this?

Thanks

You should probably just store the name of the symbol in the dictionary as a string. You may also want to do that for the floats if precision issues come up.

Sympy terms can be serialized/deserialized somewhat robustly with str and sympify.
