How do you add list in python?

Answer 1

>>> list1 = [3,5]

>>> list2 = ['foo','bar']

>>> ans = list1

>>> print ans

[3, 5]

>>> for var in list2:

ans.append(var)

>>> print ans

[3, 5, 'foo', 'bar']

this might not be the most efficient way to add lists together but it works.

ans.append(var) means to add the variable 'var' to the end of list 'ans'. the reason I put this in a for loop is if I just said ans.append(list2), the answer would be [3,5,['foo,bar']].

Answer 2

It depends on how you want to organize it, but for anything basic you want to use the sort method.
