I did not understand what i have to do here : "Create a function named nchoices() that takes an iterable and an integer"

i did not understand what is the task that the function should do here : "Create a function named nchoices() that takes an iterable and an integer. The function should return a list of n random items from the iterable where n is the integer. Duplicates are allowed." can someone clear it for me with an example of the input and expected output

The Task: Create a function named nchoices() that takes an iterable and an integer. The function should return a list of n random items from the iterable where n is the integer.

Step by step this would be:

# Create a function named nchoices()....
def nchoices():
    pass

# that takes an iterable and an integer [as arguments]
def nchoices(iter1, num):
    pass

# The function should return a list....
def nchoices(iter1, num):
    new_list = []
    return new_list

# of n random items from the iterable where n is the integer.**
def nchoices(iter1, num):
    new_list = []
    # add num random items from iterable to new_list
    for _ in range(num):
        new_list.append(random.choice(iter1))
    return new_list
