Why script from Jupyter is not working in VS Code? [duplicate]

Why this python code cannot be executed in VS Code but works in Jupyter notebook? how do you print the output?

def get_even(numbers):    return [num for num in numbers if not num % 2]get_even([1, 2, 3, 4, 5, 6])

output expected is:

[2, 4, 6]
