Array Indexing - Problem Solving with Python
The array above contains three values: 2, 4 and 6.Each of these values has a different index. Remember counting in Python starts at 0 and ends at n-1.. The value 2 has an index of 0. We could also say 2 is in location 0 of the array. The value 4 has an index of 1 and the value 6 has an index of 2.The table below shows the index (or location) of each value in the array.
