      Array Exercises

      Python Tutorial

      This Python tutorial has been written for the beginners to help them understand the basic to advanced concepts of Python Programming Language. After completing this tutorial, you will find yourself at a great level of expertise in Python, from where you can take yourself to the next levels to become a world class Software Engineer.

      Array Exercises

      Example 1

      Python program to find the largest number in an array
      import array as arr
      a = arr.array('i', [10,5,15,4,6,20,9])
      print (a)
      largest = a[0]
      for i in range(1, len(a)):
         if a[i]>largest:
            largest=a[i]
      print ("Largest number:", largest)
      It will produce the following output
      array('i', [10, 5, 15, 4, 6, 20, 9])
      Largest number: 20
      

      Example 2

      Python program to store all even numbers from an array in another array
      import array as arr
      a = arr.array('i', [10,5,15,4,6,20,9])
      print (a)
      b = arr.array('i')
      for i in range(len(a)):
         if a[i]%2 == 0:
            b.append(a[i])
      print ("Even numbers:", b)
      It will produce the following output
      array('i', [10, 5, 15, 4, 6, 20, 9])
      Even numbers: array('i', [10, 4, 6, 20])

      Example 3

      Python program to find the average of all numbers in a Python array 
      import array as arr
      a = arr.array('i', [10,5,15,4,6,20,9])
      print (a)
      s = 0
      for i in range(len(a)):
         s+=a[i]
      avg = s/len(a)
      print ("Average:", avg)
      
      # Using sum() function
      avg = sum(a)/len(a)
      print ("Average:", avg)
      It will produce the following output
      array('i', [10, 5, 15, 4, 6, 20, 9])
      Average: 9.857142857142858
      Average: 9.857142857142858

      Exercise Programs

      • Python program find difference between each number in the array and the average of all numbers
      • Python program to convert a string in an array
      • Python program to split an array in two and store even numbers in one array and odd numbers in the other.
      • Python program to perform insertion sort on an array.
      • Python program to store the Unicode value of each character in the given array.

      Practice with Online Editor
