# List as Argument
> This article explores passing lists as arguments to Python functions, enhancing flexibility and demonstrating with a function that multiplies list elements by 2.
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:
```python theme={null}
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:
```python theme={null}
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.
