To use the sys.is_finalizing() function, you need to import the sys module:

import sys

Once you have imported the module, you can call the is_finalizing() function to check if the interpreter is in the finalization phase:

if sys.is_finalizing():
    print("The interpreter is finalizing.")
else:
    print("The interpreter is not finalizing.")

The is_finalizing() function returns True if the interpreter is finalizing, and False otherwise. You can use this information to perform different actions or handle specific scenarios accordingly.

It’s important to note that the is_finalizing() function is available in Python 3.10 and above. If you are using an older version of Python, this function may not be available.

By using sys.is_finalizing(), you can determine if the Python interpreter is in the process of shutting down or finalizing. This can be useful in scenarios where you need to perform cleanup operations or handle the finalization phase differently.
