How to leave the program open in python

Question

I made a program that reads a file but it reads and already closes, how to add a 'Press S to exit' for example and leave the print on the screen for longer? -below is the code

lista=open('item.txt','r')
for linha in lista
 itens=linha.split()
 print('Comprar', itens[0])
 linha=lista.readline()

lista.close()

Answer 1

To make a code run forever and you dehydrate when the code should use while True:

while True:
    lista=open('item.txt','r')
    for linha in lista
        itens=linha.split()
        print('Comprar', itens[0])
        linha=lista.readline()


    resultado = input("Deseja encerrar, [y/n] ")
    if resultado.upper() == 'Y':
        lista.close()
        break

This way the code keeps running until the user asks to exit, typing y to exit.

Answer 2

To do this just takes one input emptiness

# insira-o no final do seu código
input('Aperte qualquer tecla para fechar o programa...')

;)

Answer 3

The "r" parameter is for reading, each line that goes through the FOR overriding the first one, try changing to "a" of "appending"

Before:

lista=open('item.txt','r')

Afterward:

lista=open('item.txt','a')

'r#open for Reading (default) 'w' open for writing, truncating Theile first 'x' open for exclusive Creation, failing if the file already exists if it exists 'a' open for writing, appending to the end of the file b 'Binary mode’t 'text mode (default) '+' open a disk file for updating (Reading and writing)
