[solved ]Pythonic drama with variable-CodePudding

in python I have this set of variable

variable.py

#--------------Project 1--------------#
ip_server = '10.10.55.98'
username = 'user_1'
distro = 'debian'

#--------------Project 2--------------#
ip_server = '10.10.55.96'
username = 'user_2'
distro = 'opensuse'

#--------------Project 3--------------#
ip_server = '10.10.55.95'
username = 'user_3'
distro = 'ubuntu'

In the script main.py I just want to import variable of Project 2, how to this?

main.py

from variable import *

ho_to_import_variable_of_project2?

thanks to all for answers anche time to dedicate my question

Your assumption that using comments to "separate" the variables to logical groups means anything to the interpreter is wrong. All you are really doing is overwriting the same variables.

Also, avoid using import *.

Instead, I'd use a dictionary:

data = {
    'Project 1': {
        'ip_server': '10.10.55.98',
        'username': 'user_1',
        'distro': 'debian'
    },
    'Project 2': {
        'ip_server': '10.10.55.96',
        'username': 'user_2',
        'distro': 'opensuse'
    },
    'Project 3': {
        'ip_server': '10.10.55.95',
        'username': 'user_3',
        'distro': 'ubuntu'
    }
}

then use it:

from variable import data

print(data['Project 1']['ip_server'])

will output

10.10.55.98

At this point you might as well use an external JSON file as a config file but that is behind the scope of this question/answer.

Create a list and dictionary for each project like below:

variable.py

project1 = [{'ip_server' :'10.10.55.98', 'username':'user_1', 'distro' : 'debian'}]
project2 = [{'ip_server' :'10.10.55.95', 'username':'user_2', 'distro' : 'opensuse'}]
project3 = [{'ip_server' :'10.10.55.96', 'username':'user_3', 'distro' : 'ubuntu'}]

And in main.py

from variable import project1
