List Comprehension
List comprehension is an excellent technique for creating lists whose content obeys simple rules (do you remember numerical sequences 😉 ).
For example if you want a list with the first five numbers squared.
lista = [i**2 for i in range(5)]
print(lista)if you run it, you get
>>>
[0, 1, 4, 9, 16] In addition there are also list comprehensions with a more complex construct that in addition to the for loop also has an if clause. For example if we wanted only the even values of the previous list.
lista = [i**2 for i in range(5) if i**2 % 2 == 0]
print(lista)if you run it, you get
>>>
[0, 4, 16]
