Step-by-Step Execution:
Importing nullcontext from contextlib:
nullcontext is a do-nothing context manager.
It is useful when you need a placeholder for a context manager but don’t actually need to manage any resources.
Using with nullcontext():
The nullcontext() context manager does not change the execution flow.
It behaves as if the with statement isn't there.
Executing print("Inside block"):
Since nullcontext() does nothing, "Inside block" is printed normally.
Expected Output:
Inside block
