pprint

问题 In other words, what's the sprintf equivalent to pprint? 回答1: The pprint module has a command named pformat, for just that purpose. From the documentation: Return the formatted representation of object as a string. indent, width and depth will be passed to the PrettyPrinter constructor as formatting parameters. Example: >>> import pprint >>> people = [ ... {"first": "Brian", "last": "Kernighan"}, ... {"first": "Dennis", "last": "Richie"}, ... ] >>> pprint.pformat(people, indent=4) "[ { 'first

问题 Is there a way to tell pprint in Python 3 not to split strings on whitespace? Python 2's pprint did not do this. Can this behavior be disabled? I looked through the source for pprint and it doesn't look like there's an option I saw for this. Can I trick it somehow? Here's an example of what I'm getting: >>> PP.pprint("ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZ",width=-1,compact=True) (

问题 I'm trying to get a pretty print of a dictionary, but I'm having no luck: >>> import pprint >>> a = {'first': 123, 'second': 456, 'third': {1:1, 2:2}} >>> pprint.pprint(a) {'first': 123, 'second': 456, 'third': {1: 1, 2: 2}} I wanted the output to be on multiple lines, something like this: {'first': 123, 'second': 456, 'third': {1: 1, 2: 2} } Can pprint do this? If not, then which module does it? I'm using Python 2.7.3. 回答1: Use width=1 or width=-1 : In [33]: pprint.pprint(a, width=1) {'first

问题 I have a nested dictionary structure with tuple keys. Here's what an entry looks like when I pretty-print the dictionary using pprint: ... ('A', 'B'): {'C': 0.14285714285714285, 'D': 0.14285714285714285, 'E': 0.14285714285714285, 'F': 0.14285714285714285, 'G': 0.14285714285714285, 'H': 0.14285714285714285, 'I': 0.14285714285714285}, ... It's pretty nifty, but I'd like to customize it further by cutting down some extra digits from the floats. I was thinking that it'd be possible to achieve by

问题 I have this code import json from pprint import pprint json_data=open('bookmarks.json') jdata = json.load(json_data) pprint (jdata) json_data.close() How can I search through it for u'uri': u'http: ? 回答1: As json.loads simply returns a dict, you can use the operators that apply to dicts: >>> jdata = json.load('{"uri": "http:", "foo", "bar"}') >>> 'uri' in jdata # Check if 'uri' is in jdata's keys True >>> jdata['uri'] # Will return the value belonging to the key 'uri' u'http:' Edit: to give

问题 When running the celery worker then each line of the output of the pprint is always prefixed by the timestamp and also is being stripped. This makes it quite unreadable: [2015-11-05 16:01:12,122: WARNING/Worker-2] { [2015-11-05 16:01:12,122: WARNING/Worker-2] u'key1' [2015-11-05 16:01:12,122: WARNING/Worker-2] : [2015-11-05 16:01:12,122: WARNING/Worker-2] 'value1' [2015-11-05 16:01:12,122: WARNING/Worker-2] , u'_id': [2015-11-05 16:01:12,122: WARNING/Worker-2] ObjectId(

问题 I have a Python script which processes a .txt file which contains report usage information. I'd like to find a way to cleanly print the attributes of an object using pprint's pprint(vars(object)) function. The script reads the file and creates instances of a Report class. Here's the class. class Report(object): def __init__(self, line, headers): self.date_added=get_column_by_header(line,headers,"Date Added") self.user=get_column_by_header(line,headers,"Login ID") self.report=get_column_by
