Python – Incremental List Extension
Sometimes, while working with Python list, we can have a problem in which we need to extend a list in a very customized way. We may have to repeat contents of list and while doing that, each time new list must add a number to original list. This incremental expansion has applications in many domains. Let’s discuss a way in which this task can be performed.
Method : Using list comprehension
This task can be performed in a brute manner, but having a shorter implementation using list comprehension always is better. In this, we perform task in 2 steps, first we make a helper list to form a addition factor list and then cumulate the result using original list.
The original list is : [7, 8, 9] List after extension and addition : [7, 8, 9, 10, 11, 12, 16, 17, 18, 34, 35, 36]
