Passing function return as parameter to another function

Question

This code has 2 functions one for taking a list from user and the other one should remove the duplications in this list , it can be done without using functions but im learning functions in Python. How can I take the list that the user has entered in function take_list() and pass it to the function no_duplication() ? when I do it i get this error

Unresolved reference 'k'

at the line : no_duplication(k)

def take_list():
    k = []
    i = 0
    list_length = int(input("how many elements your list has ? \n "))
    while i < list_length:
        element = int(input("enter you list elements : "))
        k.append(element)
        i += 1
    print(k, "  is your list")
    return k

def no_duplication(k):
    k = set(k)
    k = list(k)
    print(k, " Your list without duplications")
 

take_list()
no_duplication(k)

k is undefined in the last line of your code. You want k=take_list() and then no_duplication(k). Or, taken together, you can do: no_duplication(take_list()). — trincot

@MrXQ, just to avoid confusion - k in k = take_list() is different variable from k used inside the function body. One can use different name if they want. — buran

You need to assign returned value to a new variable and pass that to no_duplication as parameter:

k = take_list()
no_duplication(k)
