How do I slice a specific part?

Suppose I have a list of gagets and I want to slice some items that lie in the middle of my list or around it. Let me show you below:

# Here below is a list of gadgets:
gadgets= ['Laptop', 'Phone', 'Power bank', 'Charger', 'Tablet',
           'Monitor', 'Keyboard', 'Charger', 'Processor', 'Head phone']

Slicing is crucial for me. Can someone explain how slicing works with cases, for example accessing items from 4 to 8 and store them in a new list?
