XXX + +The limits on the size of expressions and file in Python source code +have been raised from 2**16 to 2**32. Previous versions of Python +were limited because the maximum argument size the Python VM accepted +was 2**16. This limited the size of object constructor expressions, +e.g. [1,2,3] or {'a':1, 'b':2}, and the size of source files. This +limit was raised thanks to a patch by Charles Waldman that effectively +fixes the problem. It is now much more likely that you will be +limited by available memory than by an arbitrary limit in Python. + +The interpreter's maximum recursion depth can be modified by Python +programs using sys.getrecursionlimit and sys.setrecursionlimit. This +limit is the maximum number of recursive calls that can be made by +Python code. The limit exists to prevent infinite recursion from +overflowing the C stack and causing a core dump. The default value is +1000. The maximum safe value for a particular platform can be found +by running Misc/find_recursionlimit.py.
