Unable to change instance attribute

I have made my own Class Button and I'm trying to modify self.text_color(in mybutton.py under [#Rectangle (comment)] ) from main.py with this command button1.text_color = (25,25,25) but I can't see any change. All other properties are modifying except this one. You copy and run the code to check the problem.

main.py

import pygame
import sys
from mybutton import Button
pygame.init()
screen = pygame.display.set_mode((500, 300))
pygame.display.set_caption('Gui Menu')
clock = pygame.time.Clock()

button1 = Button('Click me', (255,255,255), (255,0,0), 200, 40, ((500-200)//2, 200))
button2 = Button('Click me', (2,25,255), (255,25,255), 200, 40, ((500-200)//2, 100))
button1.text_color = (25,25,25)
button1.hov_bg_color = (25,255,25)
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    screen.fill((0,0,0))
    a = button1.draw(screen)
    b = button2.draw(screen)
    
    print(button1.text_color)
    
    if a != None:
        print(a)
    elif b != None:
        print(b)

    pygame.display.update()
    clock.tick(60)

mybutton.py

import pygame
pygame.init()


class Button:
    unq_number = 0

    def __init__(self, text, bg_color, hov_bg_color, width, height, pos):
        self.pressed = False

        # unique number for each button
        Button.unq_number += 1
        self.unq_number = Button.unq_number

        # Rectangle
        self.org_width = width
        self.rect = pygame.Rect(pos, (width, height))
        self.border_radius = 12
        self.org_bg_color = bg_color
        self.bg_color = self.org_bg_color
        self.hov_bg_color = hov_bg_color
        self.trans_speed = 4
        self.trans_len = 30
        self.font = pygame.font.Font(None, 30)
        self.text_color = (0, 0, 0)

        # text
        self.text_surf = self.font.render(text, True, self.text_color)
        self.text_rect = self.text_surf.get_rect(center=self.rect.center)

    def draw(self, surface):
        pygame.draw.rect(surface, self.bg_color, self.rect,
                         border_radius=self.border_radius)
        surface.blit(self.text_surf, self.text_rect)
        return self.check_click()

    def check_click(self):
        mouse_pos = pygame.mouse.get_pos()

        if self.rect.collidepoint(mouse_pos):
            self.bg_color = self.hov_bg_color
            if self.rect.width < (self.org_width + self.trans_len):
                self.rect.width += self.trans_speed
                self.rect.x -= self.trans_speed/2

            if pygame.mouse.get_pressed()[0]:
                self.pressed = True
            else:
                if self.pressed == True:
                    self.pressed = False
                    return self.unq_number
        else:
            if self.rect.width > self.org_width:
                self.rect.width -= self.trans_speed
                self.rect.x += self.trans_speed/2
            self.bg_color = self.org_bg_color

The color of the text doesn't magically change when the text_color attribute is changed. The text_color is not tied to the surface rendered by the text, you must re-render the text with the new color if you change the color.

Add a method that changes the color attribute and renders the text with the new color:

class Button:
    def __init__(self, text, bg_color, hov_bg_color, width, height, pos):
        # [...]

        self.text = text

    def set_text_color(self, color)
        self.text_color = color
        self.text_surf = self.font.render(self.text, True, self.text_color)
        self.text_rect = self.text_surf.get_rect(center=self.rect.center)

Call this method instead of changing the attribute:

button1.set_text_color((25,25,25))

i think you need to change self.text_surf as well when you set the self.color

you probably need to make a methode def set_text_color() that change self.text_surf text's color
