The mathparse library is a Python module designed to evaluate mathematical equations contained in strings.

Here are a few examples:

from mathparse import mathparse

mathparse.parse('50 * (85 / 100)')
>>> 42.5

mathparse.parse('one hundred times fifty four', mathparse.codes.ENG)
>>> 5400

mathparse.parse('(seven * nine) + 8 - (45 plus two)', language='ENG')
>>> 24

pip install mathparse

The language parameter must be set in order to evaluate an equation that uses word operators. The language code should be a valid ISO 639-2 language code.

See release notes for changes.
