What does the string method split() return by default when called without arguments?

A list of words separated by whitespace

What is the difference between a shallow copy and a deep copy of a nested list?

A shallow copy is faster but cannot be modified; a deep copy is slower but mutable.

A shallow copy copies all elements, while a deep copy only copies the outer list.

A shallow copy is used for tuples, while a deep copy is used for lists.

A shallow copy creates a new outer list but shares the inner lists; a deep copy creates new inner lists as well.

A developer has a list 'items' and needs to iterate over it, printing each item with its index. Which code snippet correctly uses enumerate()?

for idx in enumerate(items): print(idx, items[idx])

for item in enumerate(items): print(item)

for idx, item in enumerate(items): print(idx, item)

for item, idx in enumerate(items): print(idx, item)
