ip_server = '10.10.55.96'
username = 'user_2'
distro = 'opensuse'

    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

    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.
