How can you implement the use of a context manager in Python without using the 'with' statement?

A context manager in Python is an object that implements the __enter__() and __exit__() methods. It is usually used with the with statement, but these methods can be called directly to achieve the same effect without with.

Example:

class MyContextManager:
    def __enter__(self):
        print("Entering context")
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        print("Exiting context")

cm = MyContextManager()
cm.__enter__()
try:
    print("Working inside context")
finally:
    cm.__exit__(None, None, None)

Thus, you can manually call __enter__() before the code block and __exit__() after it, ensuring the same actions as with."}]}]}
