What is difference between append() and extend() method for list in Python?

Question

A list can contain different types of elements but I am not able to understand how max () method work with different types of data elements.

Answer 1

It is pretty much clear from the name itself. Append means attaching something to the last of a list whereas extend means growing the existing list, Obviously from the last. In both the cases something new is added to the last of the list, but the difference will be more clearer from the example.

first_list = [10,30]
second_list = [100,101]
first_list.append([40,50])
second_list.extend([102,103])
print first_list
[10, 30, [40, 50]]
print second_list
[ 100, 101, 102, 103]

Answer 2

append: Appends object at end
x = [1, 2, 3]
x.append([4, 5])
print (x)
gives you: [1, 2, 3, [4, 5]]

extend: extends list by appending elements from the iterable
x = [1, 2, 3]
x.extend([4, 5])
print (x)
gives you: [1, 2, 3, 4, 5]
