    What I consider to be the "pythonic" solution to this problem. It's definitely inefficient to scan nums at each iteration.

    def removeElement(self, nums, val):
        """
        :type nums: List[int]
        :type val: int
        :rtype: int
        """
        while val in nums:
            nums.remove(val)
        return len(nums)
