Yield in the Context Manager

Yield didn't return anything in the previous examples.

It is possible to catch the yielded value in a variable in the as clause:

from contextlib import contextmanager

@contextmanager

def tag(name):

print("<%s>" % name)

yield 42

print("</%s>" % name)

with tag("h1") as r:

print("My string and the return value: ", r)

The output:

<h1>

My string and the return value: 42

</h1>
