[Python-ideas] Question about `list.insert`

[Ram Rachum]

Hi,

I'm curious. If I append an item to a list from the left using 
`list.insert`, will Python always move the entire list one item to the 
right (which can be super-slow) or will it check first to see whether it 
can just allocate more memory to the left of the list and put the item 
there, saving a lot of resources?


Thanks,
Ram.
