Many other languages require creating an object or container to return but with Python 39 s tuple assignment multiple value returns are easy You can use tuple assignment in a for loop to traverse a list of tuples t 39 a 39 0 39 b 39 1 39 c 39 2 for letter number in t print number letter Each time through the loop Python selects the next tuple in the list and assigns the elements to letter and number. If the for loop is big this is a huge performance problem. In Python 2 it used to return a list of tuples of the size equal to the shortest of the input iterables. NET languages the parameters for methods of all non F assemblies are treated as tuples. Each one of them is numbered starting from zero the first one is numbered zero the second 1 the third 2 etc. Since Python is an evolving language other sequence data types may be added. How to sort a list with multiple keys For example you have a list of tuples 1 1 2 0 0 1 0 1 0 0 1 2 1 4 0 and you want to sort after the second tuple value first.
