No whole number is too large for Python! Just attach an "L", which we all
know is the symbol of: Integer Repair Man! vis,

>>> x = 0x26100511FFFF
OverflowError: integer literal too large
>>> x = 0x26100511FFFFL   # Our hero!
>>> x
41850246397951L
>>> hex(x)        # hex() works where "%x"%x doesn't, with long integers
'0x26100511FFFFL'
>>> hex(x)[2:-1]  # to strip off the leading "0x" and trailing "L", if desired
'26100511FFFF'
