unique. Python just connects the two together into a new
list, as shown in the following example:

>>> a = [1, 2, 4]

>>> b = [4, 5, 6]

>>> c = a + b

>>> print(c)

[1, 2, 4, 4, 5, 6]

Remember all of the slicing you saw with strings? The
same principles apply here, but instead of having a single
string with each letter being in a bucket, the elements in
the list are the items in the bucket. Don’t forget the rule
about the second number after the colon, which means
“up to but not including.” Here is an example:

>>> c= [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

>>> c[1:4]

[2, 3, 4]

>>> c[ :-4]

[1, 2, 3, 4, 5, 6]

>>> c[:]

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
