Tuples

• For the most part, we can just consider tuples to be immutable lists

• Tuples are defined by ( )

• The items of tuples are separated by commas

• a neat trick we can do with tuples is unpacking

In [1]: atuple=('Python','2.0', ('was','released'), ['on','October','16th','2000'])

In [2]: atuple[3][3]
Out[2]: '2000'

In [3]: atuple[1]='3.0'
