Getting values from 3d arrays in python

[TheComputerdude]

I am new to Python and messing with 3d arrays I have code that looks like this

posButtons=[[200,100],[300,400],[500, 500]]

I am wondering how to get a value from inside one of the arrays ie 200

posButtons[0] is [200,100]

posButtons[1] is [300,400]

posButtons[0][0] is 200

posButtons[0][1] is 100

posButtons[1][0] is 300

posButtons[1][1] is 400

 

 

when dealing with lists of lists, think about it from left to right: someList[top level list index][bottom level list index]

 

With a normal list of ints, [1,2,3], list[0] is going to be 1. So with a nested list: [[1,2,3], [4,5,6]], list[0] will still be the first element, which in this case is a list of [1,2,3], which we can then access like a normal list, hence the double bracket notation of [m][n].
