I'm currently working on a map editor for a game in pygame, using tile maps. The level is built up out of blocks in the following structure (though much larger):

level1 = (
         (1,1,1,1,1,1)
         (1,0,0,0,0,1)
         (1,0,0,0,0,1)
         (1,0,0,0,0,1)
         (1,0,0,0,0,1)
         (1,1,1,1,1,1))

where "1" is a block that's a wall and "0" is a block that's empty air.

The following code is basically the one handling the change of block type:

clicked = pygame.mouse.get_pressed()
if clicked[0] == 1:
    currLevel[((mousey+cameraY)/60)][((mousex+cameraX)/60)] = 1

But since the level is stored in a tuple, I'm unable to change the values of the different blocks. How do I go about changing the different values in the level in an easy manner?

Convert tuple to list:

>>> t = ('my', 'name', 'is', 'mr', 'tuple')
>>> t
('my', 'name', 'is', 'mr', 'tuple')
>>> list(t)
['my', 'name', 'is', 'mr', 'tuple']

Convert list to tuple:

>>> l = ['my', 'name', 'is', 'mr', 'list']
>>> l
['my', 'name', 'is', 'mr', 'list']
>>> tuple(l)
('my', 'name', 'is', 'mr', 'list')
