@pkeilbach Is this fine for you?

I was thinking more of something like this, where students need to implemet variants of slicing (sorry I should have provided more instructions here):

# Function Prompt: Implement the following slicing operations
def slicing_examples(input_list):
    """
    This function takes a list and returns a dictionary with results of different slicing operations.
    
    Implement the following:
    1. "first_three": Get the first three elements.
    2. "last_two": Get the last two elements.
    3. "reversed": Reverse the list.
    4. "skip_two": Get every second element in the list.
    5. "middle_slice": Get all elements except the first and last.
    
    Args:
        input_list (list): A list of elements.
    
    Returns:
        dict: A dictionary with keys as the operation names and values as the resulting sliced lists.
    """
    # Example structure for the return dictionary
    return {
        "first_three": None,  # Replace with slicing logic
        "last_two": None,     # Replace with slicing logic
        "reversed": None,     # Replace with slicing logic
        "skip_two": None,     # Replace with slicing logic
        "middle_slice": None, # Replace with slicing logic
    }

# Example usage:
# slicing_examples([1, 2, 3, 4, 5, 6])
# Expected output:
# {
#     "first_three": [1, 2, 3],
#     "last_two": [5, 6],
#     "reversed": [6, 5, 4, 3, 2, 1],
#     "skip_two": [1, 3, 5],
#     "middle_slice": [2, 3, 4, 5]
# }

@pkeilbach I adjusted the function and the tests

LGTM! 🚀
