sys.exit(main())

As an AI language model, I cannot run Python code. However, I can explain what the code snippet means.

`sys.exit(main())` is a line of Python code that is used to exit a Python script. `sys` is a module in Python's standard library that provides access to some variables used or maintained by the interpreter and to functions that interact strongly with the interpreter. `exit` is a function in the `sys` module that can be used to exit a Python script.

In the code snippet, `main()` is a function that is being called before the script is exited. The purpose of calling `main()` is to execute the main logic of the script before it exits.

So, the code `sys.exit(main())` exits the Python script after executing the `main()` function. It is commonly used to ensure that the script terminates properly after executing the main logic.
