will using list comprehension to read a file automagically call close()

Question

Does the following syntax close the file:

lines = [line.strip() for line in open(\'/somefile/somewhere\')]

Bonus points if you can demonstr

Answer 1

It will not. A context manager can be used to close it automatically. For example:

with open('/somefile/somewhere') as handle:
    lines = [line.strip() for line in handle]
