I'm attempting to create a list that has nine sub-lists. These sub-lists need to be able to store nine buttons, unfortunately it returns the following error:
File "C:\PythonLearning\Testing2dArrayOfButtons.py", line 18, in <module>
BButtons[count][gridX*(y)+x].grid(row=y, column=x)
IndexError: list index out of range
I believe the issue lies in the count, initially I tried using the y variable for the for loop but that didn't work at all. When using numbers 0-8 in place of the count variable it doesnt produce the error, but also doesn't dynamically place the buttons in a 2d array format.
from Tkinter import *
gridX = 9
gridY = 9
BButtons=[[] for i in range(9)]
root = Tk()
count = -1 #introduced count because 'y variable' was not working
for y in range(gridY):
count += 1
for x in range(gridX):
print count
BButtons[count].append(Button(root, text="X", height = 2, width = 4))
print count
print BButtons
BButtons[count][gridX*(y)+x].grid(row=y, column=x) #gridX*(y)+x is the formula used to obtain the nested button location
print BButtons #the buttons[][].grid is setting the button positions on the scrin to a grid
print BButtons
root.mainloop()
BButtons[count][gridX*(y)+x]
gridX has the value 9 which makes gridX*(y)+x be quite big number as y increases. That will cause IndexError.
BButtons[y][x] should work.
