# append will add it as if you're adding a new list to it
my_list.append([34523, 76979])
print(my_list)

# extend will go over each item in the new source list and add each
# element as part of the target list (my_list)
my_list.extend([12, 99])
print(my_list)

""" 
Output:
[23, 11, 42, 24523, [34523, 76979]]
[23, 11, 42, 24523, [34523, 76979], 12, 99]

Example 6: python how to append to a list

# Basic syntax:
your_list.append('element_to_append')

# Example usage:
your_list = ['a', 'b']
your_list.append('c')
print(your_list)
--> ['a', 'b', 'c']

# Note, .append() changes the list directly and doesn’t require an 
#	assignment operation. In fact, the following would produce an error:
your_list = your_list.append('c')
