contextlib.contextmanager

Lab Python Advanced 30 points

Hints

Code before yield runs on enter; code after it runs on exit.

Use try/finally so the closing tag always prints.

Solution explanation

@contextmanager turns a simple generator into a context manager — no class needed.

Show solution

from contextlib import contextmanager


@contextmanager
def tag(name):
    print(f"<{name}>")
    try:
        yield
    finally:
        print(f"</{name}>")


name = input()
words = input().split()
with tag(name):
    for w in words:
        print(w)
