Just do that:

List_new = [int(i) for i in List if i.isnumeric()]

You can use .isdigit()

List_given =["2","10","15","23","exit"]
def new_list(List_given):
    List_new = []
    for item in list(List_given):
        if item.isdigit():
            List_new.append(item)
    return List_new
new_list(List_given)

You can use isnumeric

>>> List=["2","10","15","23","exit"]
>>> output = [int(i) for i in List if i.isnumeric()]
>>> print(output)
[2, 10, 15, 23]
