A Tuple is an immutable collection of ordered items.
Items in the tuple can be of any type: strings, numbers, dictionaries, lists, objects, ...

Use parentheses (()) to create a tuple.
Use commas to separate items in the tuple. x = (0, 1, 2, 3) print(type(x)) # ==> <class 'tuple'> print(x) # ==> (0, 1, 2, 3) print(x[1]) # ==> 1 y = (0,) # a tuple with one item print(y) # ==> (0,) z = (x, y, 'a') print(z) # ==> ((0, 1, 2, 3), (0,), 'a')
If you try to modify a tuple you get an error: x[0] = 3 # ==> TypeError: 'tuple' object does not support item assignment
