In this article, we explore how to pass lists as arguments to Python functions, enhancing flexibility beyond just handling strings and numbers. We will demonstrate this concept by creating a function named multiply_values that accepts a list and returns a new list with each element multiplied by 2. Below is the implementation of the function: 
def multiply_values(lst):
    multiplied_values = []
    for item in lst:
        multiplied_values.append(item * 2)
    return multiplied_values
In the function above, we:
  1. Initialize an empty list called multiplied_values.
  2. Iterate over each element in the provided list.
  3. Multiply each element by 2 and append the result to multiplied_values.
  4. Return the new list containing the multiplied values.
When calling the function, ensure that the argument provided is an iterable (e.g., a list). Passing a non-iterable, like an integer, will result in a runtime error.
Let’s test the multiply_values function with a sample list: 
print(multiply_values([1, 2]))
When you run this code, the output will be a new list: [2, 4], where each element from the original list has been doubled.
