pretty-print

I am using lxml.html to generate some HTML. I want to pretty print (with indentation) my final result into an html file. How do I do that? This is what I have tried and got till now (I am relatively new to Python and lxml) : import lxml.html as lh from lxml.html import builder as E sliderRoot=lh.Element("div", E.CLASS("scroll"), style="overflow-x: hidden; overflow-y: hidden;") scrollContainer=lh.Element("div", E.CLASS("scrollContainer"), style="width: 4340px;") sliderRoot.append(scrollContainer) print lh.tostring(sliderRoot, pretty_print = True, method="html") As you can see I am using the

I'm fixing some PHP scripts and I'm missing ruby's pretty printer. i.e. require 'pp' arr = {:one => 1} pp arr will output {:one => 1}. This even works with fairly complex objects and makes digging into an unknown script much easier. Is there some way to duplicate this functionality in PHP? Both print_r() and var_dump() will output visual representations of objects within PHP. $arr = array('one' => 1); print_r($arr); var_dump($arr); Joel Hernandez This is what I use to print my arrays: <pre> <?php print_r($your_array); ?> </pre> The magic comes with the pre tag. For simplicity, print_r() and

Does anyone know of a simple way to pretty-print JSON output in Go? The stock http://golang.org/pkg/encoding/json/ package does not seem to include functionality for this (EDIT: it does, see accepted answer) and a quick google doesn't turn up anything obvious. Uses I'm looking for are both pretty-printing the result of json.Marshal and just formatting a string full of JSON from wherever, so it's easier to read for debug purposes. By pretty-print, I assume you mean indented, like so { "data": 1234 } rather than {"data":1234} The easiest way to do this is with MarshalIndent , which will let you

I use Spring, Jersey and Jackson to provide an API that produces JSON. My @Component has a @Get method that returns Response.ok(entity).build(). That output is very compact. How do I make that output pretty / formatted? 来源： https://stackoverflow.com/questions/6176881/how-do-i-make-jacksons-build-method-pretty-print-its-json-output

I have a list L of elements, say natural numbers. I want to print them in one line with a single space as a separator. But I don't want a space after the last element of the list (or before the first). In Python 2, this can easily be done with the following code. The implementation of the print statement (mysteriously, I must confess) avoids to print an extra space before the newline. L = [1, 2, 3, 4, 5] for x in L: print x, print However, in Python 3 it seems that the (supposedly) equivalent code using the print function produces a space after the last number: L = [1, 2, 3, 4, 5] for x in L:

Let's say I have a binary tree data structure defined as follows type 'a tree = | Node of 'a tree * 'a * 'a tree | Nil I have an instance of a tree as follows: let x = Node (Node (Node (Nil,35,Node (Nil,40,Nil)),48,Node (Nil,52,Node (Nil,53,Nil))), 80,Node (Node (Nil,82,Node (Nil,83,Nil)),92,Node (Nil,98,Nil))) I'm trying to pretty-print the tree into something easy to interpret. Preferably, I'd like to print the tree in a console window like this: _______ 80 _______ / \ _ 48 _ _ 92 _ / \ / \ 35 52 82 98 \ \ / 40 53 83 What's an easy way to get my tree to output in that format? If you want it

I am looking for a nice way to pretty-print a Map . map.toString() gives me: {key1=value1, key2=value2, key3=value3} I want more freedom in my map entry values and am looking for something more like this: key1="value1", key2="value2", key3="value3" I wrote this little piece of code: StringBuilder sb = new StringBuilder(); Iterator<Entry<String, String>> iter = map.entrySet().iterator(); while (iter.hasNext()) { Entry<String, String> entry = iter.next(); sb.append(entry.getKey()); sb.append('=').append('"'); sb.append(entry.getValue()); sb.append('"'); if (iter.hasNext()) { sb.append(',')
