How to print out Tree Structure?

How do you print a python unicode data structure?

• I figured out how to print python unicode with Chinese characters on to a web page and see the characters: print u_char.encode('utf-8') But if i have a data structure that contains unicode strings, how can i print the data structure and see the characters (in python 2.7)? eg: pprint(data_struct) [ u"您好", "world" ]

• Answer:

  You can do this in Python 2 by subclassing pprint.PrettyPrinter: # coding=utf-8 import pprint _escape = dict((q, dict((c, unicode(repr(chr(c)))[1:-1]) for c in range(32) + [ord('\\')] + range(128, 161), **{ord(q): u'\\' + q})) for q in ["'", '"']) class MyPrettyPrinter(pprint.PrettyPrinter): def format(self, object, context, maxlevels, level): if type(object) is unicode: q = "'" if "'" not in object or '"' in object \ else '"' return ("u" + q + object.translate(_escape[q]) + q, True, False) return pprint.PrettyPrinter.format( self, object, context, maxlevels, level) pp = MyPrettyPrinter() pp.pprint([u"您好", 'world']) Python 3 does what you want out-of-the-box: Python 3.2.2 (default, Sep 5 2011, 21:17:14) [GCC 4.6.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import pprint >>> pprint.pprint(["您好", "world"]) ['您好', 'world']
