How to delete a value in a list without using .remove?

Question

I have

x = 1

list = [1,2,3]

I want to remove the 1 in the list by referencing its value of x,not the index - without using list.remove(x). How is this possible?

Nothing, I'm just wondering if there is another way in python to accomplish this. — Emilia Clarke

Indeed, there is a lot of way to do that.

x = 5
my_list = [1, 2, 3, 5, 6, 9, 4]

del my_list[my_list.index(x)]

or

my_list.pop(my_list.index(x))

But what if I don't know the index of x, just the value?

But this code do exactly that! You can change x to any value you want.

Ohh! Sorry I'm sorda new to Python, it took me a second to fully understand your code. Thanks!

x = 1
list = [1,2,3]
list = [i for i in list if i != x]

list = [1,2,3]

OP says "I want to remove the 1 in the list by referencing its value of x", so it seems the code ought to use x
