Iterating over Indices in Python

In one of my previous articles we were talking about iterating over ranges. Today we’ll learn how to use the range function to iterate over the indices of a sequence.

You can use the range function if you want to iterate over the indices of a sequence. All you have to do is pass the length of the sequence as the argument to the range function:

 cars = ["Porsche", "Chevrolet", "Peugeot", "Honda"]
  
 for index in range(len(cars)):
     print(cars[index] + " is at index " + str(index) + ".") 

And here’s the output:

 Porsche is at index 0.
 Chevrolet is at index 1.
 Peugeot is at index 2.
 Honda is at index 3. 

Here the length of the list is 4 and range(4) generates the numbers 0, 1, 2 and 3, which are the indices in the list.
