Here, clients. The value of the closed property will be true if any file is closed. Create a python file with the following script to check a file is closed or not that exists in the current location. The previous example script will generate an error if the filename taken from the user does not exist in the current location.

This problem has solved in this example. The os module is used here to check the existence of the filename that will be taken from the user. The OSError generates when the rename function is called more than one time for a file that is opened already.

In the output, you will see that the os. Similarly, we can verify the existence of a directory in Python using the following built-in functions:.
