list.append([1,2]) will add the two element list as the next
element of the list.

list.extend([1,2]) is equivalent to list = list + [1, 2]
and the result is that each element of the added list
becomes it's own new element in the original list.

Is that the only difference?

From the manual:

s.extend(x) | same as s[len(s):len(s)] = x

But: (python 2.5.2)

a
[1, 2, 3]
a[len(a):len(a)] = 4
Traceback (most recent call last):
File "stdin", line 1, in module
TypeError: can only assign an iterable


Also, what is the difference between list[x:x] and list[x]?

a[3:3] = [4]
a
[1, 2, 3, 4]
a[4] = 5
Traceback (most recent call last):
File "stdin", line 1, in module
IndexError: list assignment index out of range



Thanks
