      Loop Lists

      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 Lists

      You can traverse the items in a list with Python's for loop construct. The traversal can be done, using list as an iterator or with the help of index.

      Syntax

      Python list gives an iterator object. To iterate a list, use the for statement as follows
      for obj in list:
         . . .
         . . .

      Example 1

      Take a look at the following example
      lst = [25, 12, 10, -21, 10, 100]
      for num in lst:
         print (num, end = ' ')

      Output

      25 12 10 -21 10 100

      Example 2

      To iterate through the items in a list, obtain the range object of integers "0" to "len-1". See the following example −
      lst = [25, 12, 10, -21, 10, 100]
      indices = range(len(lst))
      for i in indices:
         print ("lst[{}]: ".format(i), lst[i])

      Output

      lst[0]: 25
      lst[1]: 12
      lst[2]: 10
      lst[3]: -21
      lst[4]: 10
      lst[5]: 100
