Implementation of a custom context manager

You need to write your own context manager that can be used in a with statement. Below is an example of how the module and main file might look, where your manager will be used.

### module.py
print("Module executed")

### main.py
import module
import module as a

import contextlib

def mymanager():
    
    with mymanager():
        pass

This example demonstrates importing a module in two ways and using your context manager inside a with block. Implement the necessary functionality so that the code works correctly.
