Hello fellow qt users.

In the process of learning python I created a tictactoe game and use the PyQt5 to create a gui. Simple 3x3 grid of buttons created in a loop with a view to a 4x4 grid later. Ran into a problem, how to identify the button pressed? Code below shows ugly solution used. Putting clicked.connect statements in the loop fails as it seems the variables i and j are passed by reference so they all contain 2, 2 when the loop exits. Full code here: https://github.com/RickTee/tictacQt. I've probably missed something some were in the docs.

Qt Code: 
  1. GRID_SIZE = 3
  2. # Create our board of 9 buttons and put them in a grid
  3.         for i in range(0, GRID_SIZE ):
  4.             for j in range(0, GRID_SIZE ):
  5.                 self.button[i][j] = QPushButton()
  6.                 self.button[i][j].setMinimumSize(25, 25)
  7.                 self.button[i][j].setMaximumSize(25, 25)
  8.                 grid.addWidget(self.button[i][j], i, j)
  9.  
  10.         vbox.addLayout(grid)
  11.         # Add the warnings label
  12.         vbox.addWidget(self.labelWarn)
  13.         vbox.addStretch(0)
  14.         hbox.addLayout(vbox)
  15.         hbox.addStretch(0)
  16.         self.setLayout(hbox)
  17.  
  18.         self.button[0][0].clicked.connect(lambda: self.on_button_clicked(0, 0))
  19.         self.button[0][1].clicked.connect(lambda: self.on_button_clicked(0, 1))
  20.         self.button[0][2].clicked.connect(lambda: self.on_button_clicked(0, 2))
  21.         self.button[1][0].clicked.connect(lambda: self.on_button_clicked(1, 0))
  22.         self.button[1][1].clicked.connect(lambda: self.on_button_clicked(1, 1))
  23.         self.button[1][2].clicked.connect(lambda: self.on_button_clicked(1, 2))
  24.         self.button[2][0].clicked.connect(lambda: self.on_button_clicked(2, 0))
  25.         self.button[2][1].clicked.connect(lambda: self.on_button_clicked(2, 1))
  26.         self.button[2][2].clicked.connect(lambda: self.on_button_clicked(2, 2))
