Suppose you have list1 = ['a', 'b', 'c'] and you execute list2 = list1. If you run list1.append('d'), what will list1 and list2 be? Explain.

💡 Hint: Consider if both lists can share the same elements.

Challenge 2 Hard

Create a scenario that demonstrates an unexpected outcome when using list2 = list1 instead of slicing. Describe both outcomes when modifying one of the lists.

💡 Hint: Reflect on what happens when two variables point to the same space.
