How to find out the number of sections in config.ini set by the user?

Question

Python

Good day Dear coders,
I'm just starting my journey in learning this language, well, like all beginners, I decided to take up my idea right away. Little by little I am moving forward, but when I woke up in the morning I realized that I had made a mistake. I started looking for a solution but didn’t find it ((Sorry for the lyrical digression ....

The essence of the question:
There is a console program in Python3:

which should ping (not implemented) network nodes (cameras) specified by the user in config.ini and display their availability (UP / DOWN) in the console. If the user entered 100 sections according to a given pattern in the config and all 10 are written in the program, then what to do? How to check and run the program in accordance with the number of sections? Maybe somehow you can not write them separately in Python code?
config .ini

[cam1]
pos=1
name=cam1
area=1-st floor
ip=10.0.1.23
mac=00:1A:C2:7B:00:47

[cam2]
pos=2
name=cam2
area=2-nd floor
ip=10.0.1.24
mac=00:4A:C2:7B:10:42

[cam3]
pos=3
name=cam3
area=3-rd floor
ip=10.0.1.25
mac=00:43:C2:7B:F0:13

Wrote 3 sections for example. In my config there are currently 9 sections.

And the program itself:

import os
import sys
import configparser  # импортируем библиотеку для чтения INI файлов
import colorama # импортируем библиотеку для добавления цвета
from colorama import Fore, Back, Style
colorama.init()

config = configparser.ConfigParser()  # создаём объекта парсера
config.read("config.ini")  # читаем конфиг

print()
print(Fore.YELLOW + 'IP CCTV monitoring system')
print(Style.RESET_ALL)

Answer 1

Learn the basics of python about dictionaries and lists, learn loops and use

import configparser
from datetime import time
from pprint import pprint

config = configparser.ConfigParser()  # создаём объекта парсера
config.read("conf.ini")  # читаем конфиг
my_config_parser_dict = {s: dict(config.items(s)) for s in config.sections()}

for block in my_config_parser_dict.values():
    block['bool'] = True
    block['time'] = time(15, 20)
    print(*block.values(), sep='|')

print()
pprint(my_config_parser_dict)

Answer 2

Learn cycles.

Answer 3

I think it can be something like this.
1) Cycles
2) Classes
3) Execution and interception of OS processes
4) output formatting - here you still need to think about
to do
alignment
