range of int() type.
What is the range of a variable of type int() eg: i = int() print i.max() # 0x print i.min() # 0x is it a signed 16 bit or 32 bit or is it unsigned 16 or 32... I've noticed that it can be incremented into a new class of type long... -- http://mail.python.org/mailman/listinfo/python-list

If you need the overflow at 32K/64K, try: x 0x Gabriel Genellina Softlab SRL __ Preguntá. Respondé. Descubrí. Todo lo que querías saber, y lo que ni imaginabas, está en Yahoo!

For most purposes, Python just has integers, with 'small' ones (depending on the machine) handled more efficiently. For special purposes, you may want to use the array or struct modules. tjr -- http://mail.python.org/mailman/listinfo/python-list

Ok so the bottom line is..
if I have two arrays...
a = array.array('L')
a.append(65536L)
b = array.array('H')
b.append(a[0])
I will get the error:
File stdin, line 1, in ?
OverflowError: unsigned short is greater than maximum
This is obvious... but how do I crop off the high order bits if
necessary?
a[0]0x ?
