class Solution:
    def removeElement(self, nums: List[int], val: int) -> int:
        #0
        if val ==None or nums == None:
            return None
        if len(nums) == 0:
            return 0
        #normal
        count = nums.count(val)
        for i in range(count):
            nums.remove(val)
        return len(nums)

本来以为这样写简洁一点，结果比直接用remove还慢。。

        while val in nums:
            for num in nums:
                if num == val:
                    nums.remove(num)
        return len(nums)
