Change configuration file by configparser remove_section

Question

How to save the configuration file (.ini) after deleting an option or section?

I’m doing it this way:

test ini.

[LOCAL]
url = 'http://localhost:8080/'
username = 'usuario'
password = 'SECRET'

[TESTE]
url = 'http://localhost:8080/teste/'
username = 'usuario'
password = 'SECRET'

removes.py

import configparser

parser = configparser.ConfigParser()
parser.read('teste.ini')

print('Lendo Valores:')
for section in parser.sections():
    print(section)
    for name, value in parser.items(section):
        print(f"{name} = {value}")

parser.remove_option('LOCAL', 'password')
parser.remove_section('TESTE')

print('\Valor Modificado:')
for section in parser.sections():
    print(section)
    for name, value in parser.items(section):
        print(f"{name} = {value}")

However I can’t save the change, in the tests I did using some examples I found on the internet the file duplicates some TAGS, saves only half the file and sometimes even saves.

I continued with the tests here and ended up mixing some examples I found on the internet, so I managed to solve the problem, I do not know if it was the best way to solve the problem.

import configparser

parser = configparser.ConfigParser()
parser.read("teste.ini")

print('Lendo Valores:')
for section in parser.sections():
    print(section)
    for name, value in parser.items(section):
        print(f"{name} = {value}")

parser.remove_option('TESTE', 'password')
parser.remove_section('LOCAL')

with open("teste.ini", "w") as ArqTeste:
  parser.write(ArqTeste)
ArqTeste.close()

print('Valor Modificado:')
for section in parser.sections():
    print(section)
    for name, value in parser.items(section):
        print(f"{name} = {value}")

As I said earlier, I don’t know if it was the best way, but it was the way I was able to solve my problem and continue the development...
