Python curses 04 the getmaxyx function

sure! python curses is a module in the python standard library that provides a way to create text-based user interfaces. the `curses` module allows you to create interactive terminal applications with features like colored text, cursor movement, and keyboard input handling.

the `getmaxyx` function in python curses is used to retrieve the size of the terminal window, returning the maximum y and x coordinates (height and width) of the window.

here is an example code snippet that demonstrates the usage of the `getmaxyx` function in python curses:

in this code snippet:
- we import the `curses` module.
- the `main` function is defined, which takes `stdscr` (standard screen) as an argument. this function clears the screen, gets the maximum y and x coordinates of the terminal window using `getmaxyx`, displays this information on the screen, and waits for user input before exiting.

when you run this code, it will display the size of the terminal window (height and width) and wait for user input before exiting.

i hope this tutorial helps you understand how to use the `getmaxyx` function in python curses! let me know if you have any questions.
