Problem

Ten students' grade are 56%, 34%, 75%, 89%, 78%, 87%, 71%, 67%, 98%, 85%

1. Store their grades in an array as percent
2. Convert to decimal and store them in an array
3. Store their names in an array

Introducing Array

Solution

Compare to java array, Python array is much easier. We don't need to declare the variables and we also don't need to indicate the type of each array. Because the type of an array is automatedly set when we assign the value. So the code will be

 intArray = [56, 34, 75, 89, 78, 87, 71, 67, 98, 85]; 

Code

Solution Code

def main():
  intArray = [56, 34, 75, 89, 78, 87, 71, 67, 98, 85]
  decimalArray = [0.56, 0.34, 0.75, 0.89, 0.78, 0.87, 0.71, 0.67, 0.98, 0.85]
  stringArray =["Bill", "Bob", "Betty", "Bruce", "Byron", "Brent", "Bernadette", "Bo", "Brick", "Bridget"]

  print 'Program completed successfully.'
main()
