Change the variable array name.

Decrease the size of the array 

Cast the input to the appropriate data type.

Slide 5 - Slide



A 1 dimensional array is basically a list where we store a data set.

All the data items are of the same data type.
The numbers across the top are the index locations for each data item
If we wanted to put a value in index position 3 like so:
  score [3] = 9
If we wanted to output the value at index 5:
  print (“Value at position 5 is “, score[4])

2 Dimensional Arrays
If we want to store more than 1 piece of information about each data item we can use a two dimensional array like below:
The index locations of each row refer to an individual student
The index locations of each column refer to an individual student test score.
To place student 1’s score for test 2 of 9 we would do the following:
   testscores [1,2] = 9
