'list' object is not callable, Python error-CodePudding

I am trying to make a python function that receives two integers and returns a list of a descending order starting from the largest integer. (ex: f(2,5)=[5,4,3,2])

This is what I tried:

def f(n1: int, n2: int) -> List(int):
    if n1>n2:
        L=list(range(n2,n1 1))
        L.reverse()
    elif n1==n2:
        L=[n1]
    else:
        L=list(range(n1,n2 1))
        L.reverse()
    return L

the problem is I keep getting an error saying "'list' object is not callable" at List(int). What is wrong with List(int), please?

CodePudding user response：

There is syntax error in type annotation. For more info I recommend to read official docs about it https://docs.python.org/3/library/typing.html. To solve it you need to change List(int) to List[int]. In python the () operator is so call callable operator and performs e.g function call like f(1, 2)

CodePudding user response：

L is a object you have created.you should call the function f.

def f(n1: int, n2: int):
    if n1>n2:
        L=list(range(n2,n1 1))
        L.reverse()
    elif n1==n2:
        L=[n1]
    else:
        L=list(range(n1,n2 1))
        L.reverse()
    return L
f(2,5)
