# 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')N
# Python list mutation, adding elements
history = ["when"]
# adds item to the end of a list
history.append("how")
# ["when", "how"]
# combine lists
history.extend( ["what", "why"] ) # works with tuples too
# or
history = history + ["what", "why"]
# ["when", "how", "what", "why"]
# insert at target position
history.insert(3, "where")
# ["when", "how, "what", "where", "why"]
