[SOLVED].lower() function error

[MrTorex]

Hello everyone!
I'm new in Ren'py and in Python too.
I have a question.
I wrote a function in code that is responsible for viewing a Windows username. To check whether the username is the same with the name that the player enters at the beginning of the game, I created new variables that are equal to the computer name.lower () and player name.lower (). There is no error with the player’s name, this function does not want to work with the computer’s name. This error occurs in Ren'py, there are no errors in the Python 3 console. Help me please.
Code:
python:
name = renpy.input("Как вас зовут?" (translation "What is your name?")
name = name.strip() or ("NONAME")
import os
user = os.environ.get('username')
userl = user.lower()
namel = name.lower()
q "[userl], [namel]."
I can't insert images, so here are the links to them:

Already thanks.

you need

Code: Select all

        import os
        import pwd
        user = pwd.getpwuid( os.getuid() )[ 0 ]

instead of

Code: Select all

    import os
    user = os.environ.get('username')

I use the following code to assign the windows login name with a variable. You could use the same and then compare the input name, with the name this code reports?

Code: Select all

init python:
    if os.name == 'nt':
        import os
        
        for name in ('LOGNAME', 'USER', 'LNAME', 'USERNAME'):
            player = os.environ.get(name)
    elif os.name == 'posix':
        import os
        
        for user in ('LOGNAME', 'USER', 'LNAME', 'USERNAME'):
            player = os.environ.get('USER')

The nt section is for Windows environment. posix is for Linux. You must put this somewhere before your start label. I suggest either in its own file, or in screens.rpy

The name is assigned to the variable "player"
Here's an example usage. This code is part of my main menu:

Code: Select all

    if gui.show_name:
        vbox:
            xalign 0.97
            yalign 0.04
            
            if not renpy.variant("android"):
                text "Welcome, [player]":
                    style "main_menu_version"
            else:
                null height 2
                
            text "[config.name!t]":
                style "main_menu_title"

            text "Version [config.version]":
                style "main_menu_version"

                style "main_menu_version"
                

Thank you, but this code also does not work with .lower ().
And now I don't know what do with my error. And thank you for telling me the option that will work with Linux.

Quick note for future reference: RenPy uses Python 2.7 not Python 3.

really confused on this issue, because both mine and Imperf3kt's code do work in my case. don't you mind for some sanity checks?
what is your os?
what is your renpy version?
there is a project with Imperf3kt's code implementation attached in a zip file below. can you run it? how does it wurk?

No results
OS - Windows 7 Maximum
Ren'py v. 7.1.3.1092
My code is next:

Code: Select all

python:
        name = renpy.input("Как вас зовут?") #ENG: "What is your name?"
        name = name.strip() or ("NONAME")
        import os
        user = os.environ.get('username')

And your program prints to me that my name in lower is ЛешаЦ. IDK.

just grabbed some random advice from internets
let's see if it work

Code: Select all

label start:
    python:
        import os
        name = renpy.input("Как вас зовут?") #ENG: "What is your name?"
        name = name.strip() or ("NONAME")
        namel = name.lower()
        nameu = name.upper()
        user = os.environ.get('username')
        userl = user.lower()
        useru = user.upper()
    
        userdec1 = user.decode('utf-8')
        userdec1l = userdec1.lower()
        userdec1u = userdec1.upper()
        userdec2 = unicode(user, 'utf-8')
        userdec2l = userdec2.lower()
        userdec2u = userdec2.upper()
        userdec3 = u'%s'%user
        userdec3l = userdec3.lower()
        userdec3u = userdec3.upper()
    '[name] [namel] [nameu] \n [user] [userl] [useru] \n [userdec1] [userdec1l] [userdec1u] \n [userdec2] [userdec2l] [userdec2u] \n [userdec3] [userdec3l] [userdec3u] \n '
    return

and sorry about sanity checks - it turs out insane one is me and os.environ.get('username') returns None in macos witch of course cannot be lowered ^^
