* In the code above, the name of the module is '"os"', and the fromlist argument is not given, so the top-level package '"os"' is returned, which is equivalent to importing os with a regular import statement.
Therefore, the expression '__import__('os').getlogin()' is equivalent to 'os.getlogin()', but it dynamically imports the 'os' module at runtime instead of using a regular import statement.
