Python Tuples

• a kind of container along with lists, and dictionaries
• similar to lists, but they are immutable (can't be changed)
• tuple()
• if the tuple only has one item, it still needs a comma i.e (1,)
• python will raise an exception if you try to change it
• get elements with tuple_name[index]
• check if item is in tuple with in keyword
• can be used as keys in dictionaries
