>>>li=[1,2,3,4,5,6,7]
>>>li[1:4]
[2,3,4]
>>>li[::2]
[1,3,5,7]
I'm learning the list
I can roughly guess that [1:4] is from 1 to 4.
All of a sudden [::2] came out... I don't know what you mean
Do you mean to float one in two compartments??? Hmm...
python
If [A:B:C], A = starting point, included. B = final point, not included. C = step, interval. This is.
For example, [1:10:2] Ramen, Circulates at intervals of 2 from 1 to 9.
[::2] So you're going to cycle the indexed list at intervals of 2.
Note that [::-1] cycles the indexed list upside down.
