A simple calculator

This is a simple calculator when I try to recall my compiler courses.

Installation

Use the package manager pip to install compiler-calc.

pip install compiler-calc 

Usage

from compiler_calc.simple_calc import LexAnalysis, SyntaxAnalysis

# To highlight lexcial and syntax analysis
lex_analyser = LexAnalysis()
syntax_analyser = SyntaxAnalysis()

# You can define your own helper functions
def calculate(expr, lex=lex_analyser, syn=syntax_analyser):
    expr_list = lex(expr)
    return syn(expr_list)

calculate('5+4*3^2') # 41
calculate('1/0') # ValueError
