mathfuncs-parse 1.1.3

A small module for parsing and evaluating expressions of any number of variables

How to Use:

After importing ‘mathfuncs_parse’, create a ‘mathfuncs_parse.func(expr: str)’ object.

Available Member Functions:

• valid() -> bool Checks whether the expression is syntactically correct.

• eval() -> float Evaluates the expression. Note: only works if no variables are present.

• eval(vars: dict{str: float|int}) -> float Evaluates the expression, substituting the variables present with the values passed in the dict.

• vars() -> dict{str: float} Returns a dict containing all variables that must be passed to eval().

• add_func(name: str, func: <functionObj(float) -> float>) -> Null Adds a user-defined function to the object’s internal state. Note: calling ‘init(str)’ does not reset this.

• avail_funcs() -> dict{str: <functionObj>} Returns a dict of available functions which can be used in the current expression.
