你能在python中制作对列表进行操作的函数吗？

Question

在 python 中，你有内置函数可以对list.remove()和list.pop()等列表进行操作。

您可以制作自己的自定义函数来执行此操作吗？ 我希望能够做到这一点：

def removeAll(self,value):
  while value in self:
    self.remove(value)

list = ["1","2","3","3","4","3","5"]
list.removeAll("3")
print(list)
#Outputs '["1","2","4","5"]

只是一个例子。

Answer 1

您不能修改内置类型，但您当然可以从列表派生自己的类：

class mylist(list):
    def removeAll(self,n):
        while n in self:
            self.remove(n)

x = mylist([1,1,2,2,3,3,4,4])
x.removeAll(3)
print(x)

Answer 2

list1 = ["1", "2", "3"]

def operations_on_a_list():

    size = int(input("Enter the number of elements you want to add in the list : "))

    for i in range(size):

        value = input("Enter the element you want to add in the list : ")

        list1.append(value)
    
    return list1

print(operations_on_a_list())
