One of the strengths of a simple (yet powerful) language like Python is to achieve the same with less lines of code.
A “Pythonic” concept that proves this is list comprehensions
Simply put, it enables you concisely create a list in a single line of code based on some logic presented as an iterable object
Syntax is –
<to_be_create_list_name> = [i for i in <logic to create an iterable object(s)>]
And they powerful thing is that conditionals can be used in the above syntax of create an iterable object based on some conditional logic
Example –
You are given a list that has blank space characters in it, find out at which positions in the list do those blank space chars exist ? and create a new list with to hold those positions ( to be used downstream for a business rule)
Solution # 1 –
My original bloatey way to achieve it was
Solution # 2 –
A much more concise way discovered (through googling) that uses list comprehension 😉
Note – how the condition to check for blank chars and the loop to iterate through the link of the list, have been combined into a single line
Python 3.0, you beauty !
