Can you name the main terms related to the use of the context manager?

Key terms related to the use of context managers in Python:

• Context Manager — an object that defines __enter__() and __exit__() methods. It manages resources, ensuring they are properly opened and closed.

• with statement — a syntactic construct that simplifies working with context managers by automatically calling __enter__() and __exit__() methods.

• __enter__() method — called when entering a with block, usually initializes the resource and returns it.

• __exit__() method — called when exiting a with block, responsible for releasing resources and handling exceptions.

Example:

with open('file.txt', 'r') as f:
    data = f.read()

Here, open() returns a context manager that automatically closes the file after exiting the block.
