Just in time open files
Project description
This package provides a way to delay opening files until the something is written to the file handle. This can be convenient when opening a large number of files of which most of them will not be frequently used. To deal with resource limits a queue is used from which, when full, the least frequent file is closed.

pip install jit_open

>>> from jit_open import Handle, Queue
>>>
>>> queue = Queue()
>>> used = Handle("used.txt", queue)
>>> unused = Handle("unused.txt", queue)
