I recently needed to pretty print something from Python, but I needed the integers printed in hex rather than decimal. I overloaded the PrettyPrinter<\/code> class to do it. Here’s how:<\/p>\n


\n#!\/usr\/bin\/env python3
\nfrom pprint import PrettyPrinter<\/p>\n

class HexPrettyPrinter(PrettyPrinter):
\n def format(self, object, context, maxlevels, level):
\n repr, readable, recursive = PrettyPrinter.format(self, object, context, maxlevels, level)
\n if isinstance(object, int):
\n return “{0:x}”.format(object), readable, recursive
\n else:
\n return repr, readable, recursive
\n<\/code>
\nYou’d do something like this (untested):
\n
\nfrom hex_pprint import HexPrettyPrinter
\nhpp = HexPrettyPrinter()
\nhpp.pprint([1, 2, 3, 4, dict(a=1,b=2)])
\n<\/code><\/p>\n
