Parentheses in lists [PY]

Question

So I noticed in Py lists in 1st lecture they used [] for lists:
words=["hello", "world", "!"]
So I changed parentheses for words to basic () and it worked.

And then for range they used ():
List(range[4])
So I changed parentheses here to [] and it didn't work.

Why are different parenthses used for lists?

Answer 1

You can create a list by 2 ways basically :

1st:
[ ] braces like
l = [ < values > ]
Ex: [ 1,2,3,4,5 ]

Or like
2nd:

l = list( iterator )
ex: list( range(10) ) # range() is function, which returns an iterator.

hope it helps..

edit:
( 1,2,3,4,5 ) creates a tuple, not list

Answer 2

using this: words=["hello", "world", "!"] creates a list

using this: words=("hello", "world", "!") creates a tuple

Answer 3

list(range(4)) here list is a function

if you print this then you get result same as above means []

print(list(range(4)) will give [0, 1, 2, 3]

Which is like

words = ['hello', 'world', '!']

remeber a function has parenthesis () so list() and range() are functions.
