Understanding Python Index - Python Central

Basic Indexing: Accessing a single element with sequence[index] is an O(1) operation for most Python sequences. Slicing : Creating a slice with sequence[start:stop:step] is O(k) where k is the size of the resulting slice, as it creates a new sequence.

Array Indexing - Problem Solving with Python

Values in a 2-D array can be accessed using the general notation below: <value> = <array>[row,col] Where <value> is the value pulled out of the 2-D array and [row,col] specifies the row and column index of the value. Remember Python counting starts at 0, so the first row is row zero and the first column is column zero.. We can access the value 8 in the array above by calling the row and column ...
