Python : PrettyPrint a OrderedDictionary

pprint is a very handy module for printing out objects in a humane form.

Unfortunately it doesnt prettyprint OrderedDict objects properly.

The following is a workaround for printing a OrderedDict object in a manner close to what pprint does for a regular dict

Use json module's dumps method to print the OrderedDict

import json od = <Your OrderedDict> print(json.dumps(od, indent=4))

pprint模块 - Data pretty printer

python2.7 reference: http://docs.python.org/2/library/pprint.html

pprint适合打印非基本python类型的对象，尤其是比较复杂的多层次结构，比如常见的json数据。简单说，就是把复杂的数据结构解构，通过不同的缩进程度来区分数据结构的层次。

pprint模块定义PrettyPrinter类型

class pprint.PrettyPrinter (indent=1, width=80, depth=None, stream=None)

参数indent默认为1，代表每一递归层缩进的数目；depth控制层次的数目，数据结构的实际层次大于设定的层次数目，未展开的层次就用'...'来代替；width设定控制输出的宽度，默认为80个字符；Stream如果为None，则直接在屏幕输出（sys.stdout）

pprint模块有两个主要函数pprint()和pformat()

1)pprint.pformat(object, indent=1, width=80, depth=None)

返回重新排版过的对象（字符串类型）

2)pprint.pprint(object, stream=None, indent=1, width=80, depth=None)

排版打印对象（不改变原本数据结构）

例子：

data的结构包括了三个key，time的值是int list，day是string list，而month是dic，key为月份缩写，值为int，每个月包含的天数。如果直接打印，结构看上去不是很清晰，而是用了pprint，就一目了然了。

从上面的例子可以看出pprint没有改变data本身的数据结构显示方式，但formated_data已经变成了增加了缩进的结构。如果不给参量赋值的话都取默认值。

Clojure weekly, Jan 21st, 2013

Clojure Weekly is just a few links to clojure-related posts, blogs, screencasts, presentations or podcasts I found over the Internet. I added a summary to each one of them so you can decide if you want to spend the time to look at the original! Enjoy! fogus: pesto5: A concatenative programming library in 5 lines of Clojure This little five liner has a few interesting properties. It implements a simple concatenative language on top of Clojure, that is a language that operates on a list of operands and operators by placing them on an implicit stack where operations are performed just by going through the list left to right. For example (1 2 3) creates a "stack" and returns it like [1 2 3]. (1 2 +) returns the stack [3] where 1 was pushed, 2 was pushed, and + was used as binary operator on the two operands on the stack. It's amazing the amount of Clojure needed to obtain quite a complicated behaviour. As simple as it seems, there are languages based on the use of an implicit stack like Forth! brandonbloom/fipp · GitHub A quick note on this pretty printer. The problem of pretty printing sounds simple at first. But this little utility implements a fast algorithm backed by a few research papers nonetheless. Reducers are required, so you need to use Clojure 1.5-RC1 and in case you are not using the JDK 1.7 you also need to add the jar for the jsr-166 implementation (with [org.codehaus.jsr166-mirror/jsr166y "1.7.0"]). It also provides a nice idiomatic API to write your own pretty printing, with grouping and indentation. ClojureWise: Using ctags with Clojure Using Clojure from an ancient editor like emacs or vim? If you are using Ctags (you should) you can issue the following from the command line and start jumping around: ctags -R --langmap=Lisp:+.clj --sort=yes --exclude=.git --exclude=.svn --exclude=**/target * This will create the tags file that vim or emacs can use to jump between definitions. ClojureTV - YouTube Worth pointing out that since the glorious blipTV account was abruptly closed, the new source for Clojure presentations is now on youtube as ClojureTV. Tons of good material is here, including the Rich Hickey's playlist http://www.youtube.com/watch?v=f84n5oFoZBc&list=PLZdCLR02grLrEwKaZv-5QbUzK0zGKOOcr and many other playlists to watch your favourite talks non-stop for hours!
