What is the output of this Python code with a walrus operator?

What does this code print?

nums = [1, 2, 3, 4, 5]
if (n := len(nums)) > 3:
    print(f"List has {n} items")
else:
    print("List is small")

Python

nums = [1, 2, 3, 4, 5]
if (n := len(nums)) > 3:
    print(f"List has {n} items")
else:
    print("List is small")

A List has 5 items

B List is small

C SyntaxError

D TypeError

💡 Hint

The walrus operator assigns and returns the value in one step.

The length of the list is 5, which is greater than 3, so it prints 'List has 5 items'.
