W
A slice still has some references to the old objects a deep copy is a
totally new object!

What will a "deep copy" of a list give you that using the slice
notation will not?

or

The standard idiom (I guess) is to use the slice
>>> a=[1,2,3,4]
>>> b=a
>>> b is a
True
>>> b
[1, 2, 3, 4]
>>> c=a[:]
>>> c is a
False
>>> c
[1, 2, 3, 4]
This is shallow copy
If you want deep copy then
from copy import deepcopy

I am pretty new to python but this works:
>>> list_one = [0,1,2,3,4,5,6,7,8,9]
>>> list_two = [i for i in list_one]
>>> print list_two
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Hello Guys,
What's the best way to create a copy of a list? I've seen several method and
I'm not sure what to use. This will be in a class and one method creates a
list which I then want to move to the self scope, like so:
__Init__(self):
Self.myList = []
regenerateList
10 matches
