Python - How to replace multiple `with` statement blocks by a single `with` statement block

Question

Consider the following piece of Python code:

with open('reviews.txt', 'r') as f:
    reviews = f.read()
with open('labels.txt', 'r') as f:
    labels = f.read()

The goal is to replace the two with statements with a single with statement.

How can this be achieved?

Please elaborate on "combine the two different file openings". It's a bit vague. — seand

Why do you want to combine them? Just to make your code shorter? Are you expecting any other advantage? — Bryan Oakley

The advantage is more mental in that a single with statement corresponds to the thought 'get the reviews and labels'. — Terry Jan Reedy

@BryanOakley Terry's comment summarises my motivation. It makes the code cleaner, succinct and easier to grasp. — nightmarish

You can combine multiple open commands if you separate them by comma:

with open('reviews.txt', 'r') as f1, open('labels.txt', 'r') as f2:
    reviews = f1.read()
    labels = f2.read()
