Pretty-print a NumPy array without scientific notation and with given precision

Use numpy.set_printoptions to set the precision of the output: import numpy as np x = np.random.random(10) print(x) # [ 0.07837821 0.48002108 0.41274116 0.82993414 0.77610352 0.1023732 # 0.51303098 0.4617183 0.33487207 0.71162095] np.set_printoptions(precision=3) print(x) # [ 0.078 0.48 0.413 0.83 0.776 0.102 0.513 0.462 0.335 0.712] And suppress suppresses the use of scientific notation for small numbers: … Read more

Printing Java Collections Nicely (toString Doesn’t Return Pretty Output)

You could convert it to an array and then print that out with Arrays.toString(Object[]): System.out.println(Arrays.toString(stack.toArray()));

How do I get Python’s ElementTree to pretty print to an XML file?

Whatever your XML string is, you can write it to the file of your choice by opening a file for writing and writing the string to the file. from xml.dom import minidom xmlstr = minidom.parseString(ET.tostring(root)).toprettyxml(indent=” “) with open(“New_Database.xml”, “w”) as f: f.write(xmlstr) There is one possible complication, especially in Python 2, which is both less … Read more

Print a list of space-separated elements

You can apply the list as separate arguments: print(*L) and let print() take care of converting each element to a string. You can, as always, control the separator by setting the sep keyword argument: >>> L = [1, 2, 3, 4, 5] >>> print(*L) 1 2 3 4 5 >>> print(*L, sep=’, ‘) 1, 2, … Read more

The simplest way to comma-delimit a list?

Java 8 and later Using StringJoiner class, and forEach method : StringJoiner joiner = new StringJoiner(“,”); list.forEach(item -> joiner.add(item.toString()); return joiner.toString(); Using Stream, and Collectors: return list.stream(). map(Object::toString). collect(Collectors.joining(“,”)).toString(); Java 7 and earlier See also #285523 String delim = “”; for (Item i : list) { sb.append(delim).append(i); delim = “,”; }

Convert JSON String to Pretty Print JSON output using Jackson

To indent any old JSON, just bind it as Object, like: Object json = mapper.readValue(input, Object.class); and then write it out with indentation: String indented = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(json); this avoids your having to define actual POJO to map data to. Or you can use JsonNode (JSON Tree) as well.

How to “pretty” format JSON output in Ruby on Rails

Use the pretty_generate() function, built into later versions of JSON. For example: require ‘json’ my_object = { :array => [1, 2, 3, { :sample => “hash”} ], :foo => “bar” } puts JSON.pretty_generate(my_object) Which gets you: { “array”: [ 1, 2, 3, { “sample”: “hash” } ], “foo”: “bar” }

Pretty printing XML with javascript

From the text of the question I get the impression that a string result is expected, as opposed to an HTML-formatted result. If this is so, the simplest way to achieve this is to process the XML document with the identity transformation and with an <xsl:output indent=”yes”/> instruction: <xsl:stylesheet version=”1.0″ xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”> <xsl:output omit-xml-declaration=”yes” indent=”yes”/> <xsl:template … Read more

Pretty-Print JSON in Java

Google’s GSON can do this in a nice way: Gson gson = new GsonBuilder().setPrettyPrinting().create(); JsonParser jp = new JsonParser(); JsonElement je = jp.parse(uglyJsonString); String prettyJsonString = gson.toJson(je); or since it is now recommended to use the static parse method from JsonParser you can also use this instead: Gson gson = new GsonBuilder().setPrettyPrinting().create(); JsonElement je = … Read more

How to pretty-print a numpy.array without scientific notation and with given precision?

You can use set_printoptions to set the precision of the output: import numpy as np x=np.random.random(10) print(x) # [ 0.07837821 0.48002108 0.41274116 0.82993414 0.77610352 0.1023732 # 0.51303098 0.4617183 0.33487207 0.71162095] np.set_printoptions(precision=3) print(x) # [ 0.078 0.48 0.413 0.83 0.776 0.102 0.513 0.462 0.335 0.712] And suppress suppresses the use of scientific notation for small numbers: … Read more
