      Loop Arrays

      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.

      Loop Arrays

      Since the array object behaves like a sequence, you can iterate through its elements with the help of for loop or while loop.

      "for" Loop with Array

      Take a look at the following example
      import array as arr
      a = arr.array('d', [1, 2, 3])
      for x in a:
         print (x)
      It will produce the following output
      1.0
      2.0
      3.0

      "while L oop with Array

      The following example shows how you can loop through an array using a while loop
      import array as arr
      a = arr.array('d', [1, 2, 3])
      l = len(a)
      idx =0
      while idx<l:
         print (a[idx])
         idx+=1

      "for Loop with Array I ndex

      We can find the length of array with built-in len() function. Use the it to create a range object to get the series of indices and then access the array elements in a for loop.
      import array as arr
      a = arr.array('d', [1, 2, 3])
      l = len(a)
      for x in range(l):
         print (a[x])
      You will get the same output as in the first example.
