🧠 *Python List Slicing: Shallow Copy & Deep Copy Explained | NeuralAICodeCraft*

List slicing creates a SHALLOW COPY - but what does that mean? Learn why modifying nested lists can cause unexpected behavior!

📌 *What you'll learn:*

*SLICING BASICS*
▸ Syntax: `list[start:end:step]`
▸ Slicing creates a NEW list
▸ Original list remains unchanged

*SHALLOW COPY EXPLAINED*
▸ What is a shallow copy?
▸ Copies REFERENCES to objects (not objects themselves)
▸ Nested objects are SHARED
▸ Visual diagrams and examples

*SLICING vs OTHER METHODS*
▸ `list[:]` vs `list.copy()`
▸ `list()` constructor
▸ `copy.copy()` vs `copy.deepcopy()`

*PRACTICAL EXAMPLES*
▸ Modifying sliced lists
▸ Nested list behavior
▸ Common pitfalls
▸ When to use deep copy
