0828. Basic Mathematical Operations

Your task is to create a function that does four basic mathematical operations.

The function should take three arguments - operation(string/char), value1(number), value2(number). The function should return result of numbers after applying the chosen operation.

Examples(Operator, value1, value2) --> output ('+', 4, 7) --> 11 ('-', 15, 18) --> -3 ('*', 5, 5) --> 25 ('/', 49, 7) --> 7

Solution:

def as_string(func):
    def wrapper(*args):
        return func(*(str(i) for i in args))
    return wrapper

@as_string
def basic_op(operator, value1, value2):
    return eval(value1+operator+value2)
