Python __enter__ / __exit__ vs __init__ (or __new__) / __del__

Question

I have searched and I\'m unable to come up with any good reason to use python\'s __enter__ /__exit__ rather than __init__ (or __new_

Answer 1

del x doesn’t directly call x.__del__()

You have no control over when .__del__ is called, or in fact whether it gets called at all.

Therefore, using __init__/__del__ for context management is not reliable.
