How does the max function work when items in a list are not of the same type?
For example the following code returns [1,’3′]
max([1,52,53],[1,'3']) => [1,'3']

In Python2, the default comparison for objects of different types is to compare using the id of their types (obtained by casting the object pointers to integers). Here a link to the source: http://hg.python.org/cpython/file/2.7/Objects/object.c#l757
On my build, here is the ordering of types:
Numbers (except for complex) have compare methods that allow cross type comparison based on numeric value (i.e. a float can be compared with an int).
The None object is special. It compares less than everything else.
To see it all put together, use sorted to see the ordering:
