have you checked the python curses howto already? I have written a curses wrapper for one of my projects. Maybe it can help showing what steps you need. I've been using curses a lot for my own projects so feel free to ask me if there's something you want to know. The python curses library is mostly just a wrapper around calls to the ncurses system library. Documentation for that library or ports in other languages will likely help you in python too.

Curses Programming with Python — Python 3.14.3 documentation
Once the callable returns, wrapper() will restore the original state of the terminal. The callable is called inside a try…except that catches exceptions, restores the state of the terminal, and then re-raises the exception. Therefore your terminal won’t be left in a funny state on exception and you’ll be able to read the exception’s message and traceback. Windows are the basic abstraction in curses.

curses — Terminal handling for character-cell displays
Initialize curses and call another callable object, func, which should be the rest of your curses-using application. If the application raises an exception, this function will restore the terminal to a sane state before re-raising the exception and generating a traceback. The callable object func is then passed the main window ‘stdscr’ as its first argument, followed by any other arguments passed to wrapper().

June 10, 2019 - To accomodate this, the curses package provides a function that can wrap your whole application that way it can handle restoring things to a sane state. To use the wrapper, create a function that takes one argument: the screen.

May 10, 2021 -
I know curses is generally disliked around here, and tcod is recommended. I've tried to get tcod working on two operating systems though, and couldn't get it to work on either. I haven't tried really hard though, because curses really appeals to me, both by being the traditional library used for most of the roguelikes I played growing up, and also because of the small footprint when it comes to system resources.
There aren't many Python/Curses resources out there. I've found a few non-roguelike-specific tutorials on youtube, the Rogue Detective source, and this non-functional algorithm. I'm pretty sure this is enough for me to cobble together something playable. I'm just curious whether there are better methods I could be using.

Out of curiosity, why is curses disliked around here?

In Python you can avoid these complications and make debugging much easier by importing the module curses.wrapper. It supplies a wrapper() function that takes a callable. It does the initializations described above, and also initializes colors if color support is present.

Curses, and Other Dirty Words. When it comes to getting quick and… | by Mike Dresser | Medium
March 28, 2024 - After invoking initscr() there are a handful of other commands we’ll need to set up just to get running, to say nothing exiting cleanly, terminating all the running processes, and restoring the contents of the user’s terminal to their state before running your code. Luckily, curses provides us with a shortcut: the wrapper().

I believe you are looking for curses.wrapper See http://docs.python.org/dev/library/curses.html#curses.wrapper
It will do curses.cbreak(), curses.noecho() and curses_screen.keypad(1) on init and reverse them on exit, even if the exit was an exception.
Your program goes as a function to the wrapper, example:
def main(screen):
"""screen is a curses screen passed from the wrapper"""
...
if __name__ == '__main__':
curses.wrapper(main)

You could do this:
def main():
curses.initscr()
try:
curses.cbreak()
for i in range(3):
time.sleep(1)
curses.flash()
pass
print( "Hello World" )
finally:
curses.endwin()
Or more nicely, make a context wrapper:
class CursesWindow(object):
def __enter__(self):
curses.initscr()
def __exit__(self):
curses.endwin()
def main():
with CursesWindow():
curses.cbreak()
for i in range(3):
time.sleep(1)
curses.flash()
pass
print( "Hello World" )
