pymep 1.0.2

Python Math Expression Parser

python math expression parser is a python project where you can parse or evaluate math expressions.

This algorithm does not use a decision tree. It is a recursive algorithm.

Installation

pip install pymep

Here you can see some examples:

Real Numbers:

from pymep.realParser import parse
from pymep.realParser import eval


#Real Expresion parser
fx="cos(10)"
print(parse(fx))
xi=5
fx = "1 + x"
print(eval(fx, xi))

For complex Numbers:

from pymep.complexParser import parse
from pymep.complexParser import eval
from pymep.complex import Complex

#Operation with complex numbers
a = Complex(1,2)
print(a.__radd__(10).__complex__())
print(Complex.radd(10, a).__complex__())


#Complex Expresion parser
fx="cos(10+2j)"
print(parse(fx).__complex__())
xi=5
fx = "1 +j+x"
print(eval(fx, xi).__complex__())

There is a full list of examples inside!!

Enjoy it!!

NOTE: Regarding to the OS where you excute the tests, it is possible that some tests fail due to rounding issues. The mathematical library used in this project is "math". In the future, it is possible that the math library change.
