How do you know what kind of button was PyQt5

[Trenton]

I want to write a browser. I'm trying to figure out how to make any deposits, remove them, and generally make any other changes.

How am I supposed to know which button was hit, that's her number?

class Button(QPushButton):
    def __init__(self):
        QPushButton.__init__(self)
        self.setStyleSheet("background-color: rgb(255,0,0);")
class Window(QWidget):

def init(self, parent = None):

QWidget.init(self, parent)

self.layout = QGridLayout()

self.buttons = [Button() for i in range(100)]

i = -1

for button in self.buttons:

i+=1

button.clicked.connect(lambda: self.printer(i))   #Так все время i = 99, я бы хотел, чтобы i был равен номеру нажатой кнопки

self.layout.addWidget(button,i//30,i%30)

self.setLayout(self.layout)
def printer(self):
    self.buttons[num].setText(f"{num}")

Try this:

import sys
from PyQt5.Qt import *
class Button(QPushButton):

def init(self):

QPushButton.init(self)

self.setStyleSheet("background-color: rgb(255,0,0);")

self.setMinimumSize(30, 30)

self.setMaximumSize(30, 30)
class Window(QWidget):

def init(self, parent = None):

QWidget.init(self, parent)
    self.layout = QGridLayout()
    self.buttons = [Button() for i in range(100)]

i = -1
    for i, button in enumerate(self.buttons):

i+=1
        button.clicked.connect(lambda ch, num=i: self.printer(num))   
        self.layout.addWidget(button, i//30, i%30)
    self.setLayout(self.layout)

def printer(self, num):
    self.buttons[num].setText(f"{num}")

if name == "main":

app = QApplication(sys.argv)

window = Window()

window.show()

sys.exit(app.exec_())
