I am accepting user input in ascii math notation and need to evaluate that input in python with help from the sympy library.
For example, a user might input:
2x^2
My understanding is that to evaluate this function in python, it would need to be in format:
2*x**2
My thought is that there must already be some libraries out there that could help with notation conversion but I have been unable to find any... Any suggestions would be greatly appreciated.
The parse_expr function will help:
>>> from sympy.parsing.sympy_parser import (parse_expr, convert_xor,
standard_transformations, implicit_multiplication)
>>> parse_expr('2x^2',transformations=standard_transformations+
... (convert_xor,implicit_multiplication))
2*x**2
