list(range(10)) replace the typical []to declare a list?

Question

The are the same....right?
The lesson did not introduce this

Answer 1

Anyway, you can declare an empty list with list(range(0))... even if that's less efficient and readable than use [] ^^

And for Python2 users, don't forgot that range() will return a list, while Python3 return an iterator, as the Python2 xrange() function which was renamed in Python3 and original one deprecated...

Answer 2

Not really. Listname = [] will declare an empty list. So if you print(Listname) you will get []. If you use ListR = list(range(10)) and you print(ListR) you will get 0 through 9 in the list. So it depends on what you want/need to do.

Answer 3

Well, they are not really the same! I f you want to create a list of random objects, or objects chosen by you that are in a random order, than you may want to use:

listname = [...]

But if you want a list of consecutive numbers, you really want to use:

listname = list(range(100))

instead of typing all the numbers:

listname = ['0', '1', '2', '3', '4', '5', '6', etc...]
