How to open multiple files using "with open" in Python?

To open multiple files using "with open" in Python, we can separate each file with a comma.

For instance, we write:

with open('foo.txt', 'r') as a, open('bar.txt', 'r') as b:
    print(a.readlines())
    print(b.readlines())

We call open with 'r' to open foo.txt and bar.txt.

Then we call readlines on each file to read the content of them.

Therefore, is foo.txt has:

foo

And bar.txt has:

bar

Then we see:

['foo']
['bar']

printed.
