Hi, there
a = range(100)
if I want to use No 7, 11, 56,90 in a, then the only way I do is [a[7],
a[11], a[56], a[90]].
Is there any other way?
Thanks in advance.

I presume a = range(100) is just an indication that a is a list -- the
literal answer to your question as asked is simply [7,

a = [7, 11, 56, 90]
Are those numbers supposed to be in some sort of series? They
Thanks, John
how about indexing 1-7, 10
[range(1:8),10] will generate [[1, 2, 3, 4, 5, 6, 7], 10], instead of
[1, 2, 3, 4, 5, 6, 7, 10]

(Note that range(1:8) is a syntax error).
You can join and extend lists as you like:
range(1, 8) + [10]
[1, 2, 3, 4, 5, 6, 7, 10]
See also the list.append
Thanks, bearophile.
range(1, 8) + [10] is great!
