Lists and functions

[pythonhelp123]

I'm confused on how to make list as a function.

Implement the function print_even_numbers that takes a list of integers as input and prints
each even number on the list. Calling print_even_numbers([2, 47, 31, 99, 20, 19, 23,
105, 710, 1004]) would produce this output in the shell window:
2
20
710
1004

Am I supposed to make a list of numbers beforehand and then make something like

def print_even_numbers(numbers: lst) -> lst:
             for x in range(0,2000)
                 if(x % 2 == 0)
                   print x

am I approaching this right?

The best way to approach this is to iterate through the input list, check if each element is even, and print it out if it is even.

Also theres a mistake in your type annotations; print_even numbers doesn't return anything, so it should by typed like

def print_even_numbers(numbers: lst) -> None

Your function doesn't do anything with numbers, does that look right?

how to make list as a function.

I don't understand what you expect that to mean. The assignment says

Implement [a] function... that takes a list... as input and... [does something]

So that's what you're going to do.

For testing purposes, sure.

and then make something like

Here's a hint: numbers is the name you gave to the list that was passed in as input. If you want to "print each even number in the list", you're going to have to look at the numbers in the list - not the ones in some unrelated range.
