如何计算列表中某个数字中的多少个，然后删除这些数字？(python 2.7)

def count_and_remove_numbers(lst, num):
    count = lst.count(num)  # 计算数字出现的次数
    lst = filter(lambda x: x != num, lst)  # 删除数字
    return count, list(lst)

# 示例用法
numbers = [1, 2, 3, 4, 2, 5, 2]
target_number = 2

count, updated_numbers = count_and_remove_numbers(numbers, target_number)
print("数字 {} 出现了 {} 次".format(target_number, count))
print("更新后的列表：", updated_numbers)
