[issue2995] Idle, some Linuxes, cannot position Cursor by mouseclick

[Darrell]

Darrell  added the comment:

I'm using Mandriva 2009.0 and can confirm this problem. RMeyers
suggested testing further by loading and running idlelibs/IOBinding.py.

On my Linux system I find that the mouse clicks and selection works fine
when running IOBinding.py. Being that this module appears to be built
upon Tkinter, it would seem that the bug is at a higher level?

[issue14719] Lists: [[0]*N]*N != [[0 for _ in range(N)] for __ in range(N)]

[Darrell Long]

New submission from Darrell Long :

N = 5
board_1 = [[0 for _ in range(N)] for __ in range(N)]

is not the same as:

board_2= [[0]*N]*N

One makes a proper list of lists (the first), the second makes a new kind of 
animal were board_2[1][1] = 99 changes a whole column.

Oddly, testing board_1 == board_2 is True!

I'm teaching Python to non-majors, and this is a tough one to explain.
