[Python] Move cursor accross multiple lines in python

so i am trying to make a simple text editor to learn python , i am trying to learn by making some thing , yesterday i had asked about non blocking keyboard listening here and i solved that problem currently my code looks like this:

'''
imports: keyboard for listening to CTRL
readline for navigating cursor in a line
'''
import readline
# import keyboard
from pynput import keyboard
lines = ""

def write(line_count , no_of_lines):
'''
function:write
parameters:line_count,no_of_lines
returns:none
'''
global lines
print(line_count,no_of_lines)
print(f"Default line count {no_of_lines}")
print(f"Buffer Length {len(lines)}")
print("press CTRL key to set line to 1")
print("start typing")
print("--------------------------------------")
# def on_ctrl_event(event):
# nonlocal line_count
# if event.name == 'ctrl':
# line_count = 1
# keyboard.on_press(on_ctrl_event)
def on_release(key):
nonlocal line_count
if key == keyboard.Key.ctrl:
line_count = 1
# with keyboard.Listener(on_release=on_press) as listener:listener.join()
# non vlocking
listener = keyboard.Listener(on_release=on_release)
listener.start()
while line_count > 0:
lines += input() + "\n"
line_count -= 1
if line_count == 0:
print("last line")
try:
inc_line = int(input("<line> or 0: "))
except ValueError:
inc_line = 0
if inc_line > 0:
no_of_lines += inc_line
line_count += inc_line
def main():
'''
function:main
returns:none
main entry point
'''
global lines
while True:
event = input("'n' to write ,'s' to save , 'v' to view buffer , 'q' to exit: ")
if event == 's' and (len(lines)>1):
filename = input("filename>")
path = input("path>")
try:
with open(f"{path}{filename}", "w",encoding='utf-8') as file:
file.write(lines)
print("Saved the content\nBuffer is cleared")
except (OSError, FileExistsError) as error:
print(error)
elif event == 'v' and len(lines) > 1:
print(lines)
elif event == 'q':
break
elif event == "n":
lines = ""
write(5,5)
else:
print(f"Current Buffer length: {len(lines)} must be > than 1")

if __name__=="__main__":
main()
