Imitiating array of PHP by Python (just a joke)

phparray.py

 from collections import OrderedDict


class PHPArray(OrderedDict):
    def __init__(self):
        super().__init__()
        self.next_max_index = 0

    def __setitem__(self, key, val):
        if isinstance(key, int):
            if self.next_max_index <= key:
                self.next_max_index = key + 1

        super().__setitem__(key, val)

    def __iter__(self):
        return self.values()

    def push(self, val):
        self[self.next_max_index] = val


a = PHPArray()
a.push('a')
print("push('a')")
print(a)
