如何使Python 2.x Unicode字符串不打印为u'string'？

Question

I'm currently testing a webservice that returns large amounts of JSON data in the form of dictionaries. The keys and values for those dictionaries are all unicode strings, and thus they print like

{u'key1':u'value', u'key2':u'value2'}

when printed to the screen in the interactive interpreter.

Now imagine that this is a 3-level deep, 40-element dictionary. All those u characters clutter up the display, making it hard to figure out, at a glance, what the real data actually is. Even when using pprint .

Is there any way to tell the interpreter that I don't care about the difference between normal strings and unicode strings? I don't need or want the u .

The only thing I've found that might have helped was the PYTHONIOENCODING environment variable. Unfortunately, setting it to 'ascii' or 'latin-1' doesn't make those u 's go away.

I'm using Python 2.6, and I use either the regular python interpreter, or iPython.

Answer 1

if it's json you want, just print json :

>>> import json
>>> print json.dumps({u'key1':u'value', u'key2':u'value2'}, indent=4)
{
    "key2": "value2", 
    "key1": "value"
}

Answer 2

Why don't you create your own function to print the dictionary? Python's default format is OK for fast, easy debugging, but absolutely inapproapiate for a 3-level deep, 40-element dictionary.
