variable is not saved in programming

Question

I’m learning python and I’m trying to program a platform to play table rpg

my intention was to assemble a code that would take the name of a character that would be placed in an input and add it into a variable, so that this variable would be used as the player’s 'name'. The problem is that my code does not 'save' this variable.

i am using a tool called Pysimplegui to assemble a graphical interface

import PySimpleGUI as sg 
from random import randint

class ScreenRecord():
def __init__(self):
    
    layoutRecord = [
        [sg.Text('Enter character name'),sg.Input(size=(15,0),key='character')],
        [sg.Button('Enter',key = 'Enter'),]
    ]

    self.window = sg.Window('teste-mecanica').layout(layoutRecord)
    self.button,self.values = self.window.Read()

    def Enter(event):
        character = self.values['character']
        tela = ScreenDice()
    
    while True :
        event,values = self.window.Read()
        if event is None:
            break
        if event in ['Enter']:
            Enter(event)

class ScreenDice(ScreenRecord):
def __init__(self):
    
    db = {'size':(12,2)}

    layoutDice = [
        
        [sg.Button('Roll D10',key= 'd10',**db),sg.Button('Roll D20',key='d20',**db)],
        
    ]
    self.window = sg.Window('teste-dado').layout(layoutDice)

    self.button,self.values = self.window.Read()

    def RollDice(event):
        print(character ,'received', randint(1,dice),'in the dice')
            

    while True :
        event , values = self.window.Read()
        if event is None:
            break
        if event in ['d10'] :
            dice = 10
            RollDice(event)
        if event in ['d20'] :
            dice = 20
            RollDice(event)

the terminal returns me :

NameError: name 'character' is not defined

Obs: it’s my first time programming something, forgive me if it’s a stupid question

Answer 1

That one Character is not defined. It’s just a loose word.

as if I wanted to access something that doesn’t exist.

example of error.

Python 3.8.3 (default, Jun 16 2020, 17:59:42) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

>>> print(oi)  <==== tentando imprimir a palavra solta sem referencia  

Traceback (Most recent call last): File "", line 1, in Nameerror: name 'hi' is not defined

Here’s your list.

DESCULPE A FALTA DE ATENÇÃO.

in class class Screenrecord(): to a variable within a function

def Enter(Event): Character = self.values['Character']

And the other class that inherits from Screenrecord but is not calling the Character variable the right way:

inheritance

Answer 2

your class Screendice(Screenrecord) is not referencing the object of the main class and because of this detail the "Character" is not defined as it was not called as expected
