I was playing around in python. I used the following code in IDLE:
p = [1, 2]
p[1:1] = [p]
print p
The output was:
[1, [...], 2]
What is this […]? Interestingly I could now use this as a list of list of list up to infinity i.e.
p[1][1][1]....
I could write the above as long as I wanted and it would still work.
EDIT:
- How is it represented in memory?
- What’s its use? Examples of some cases where it is useful would be helpful.
- Any link to official documentation would be really useful.
