javascript - Return all properties in JS object to "empty" state -

-

I wonder if the jQuery function has any utility function, then the JS object is scaled down ( There are more than one possible result, not sure what is most useful yet): 

  {// original object foo: "bar", arr: [1, 2, 3], Sub: {a: 4, b: 5, subsub: {c: 6}}} {// cut, version 1 foo: "", arr: [], sub: {}} {// has been reduced, Version 2 foo: "", arr: [], sub: {subsub: {}}} {// tuncated, variant 3 fu: "", ar: [], sub: {a: 0, b: 0, subsub : {C: 0}}}   
 If not, then all the properties are more cunning than iterated iterations, check the type and reset / reset as needed?  
  
 
 
 Call Constructor for each property to create an object's empty object.  [obj] = obja [k] & amp; Amp; Obj [k] .constructor (); }   
 This will also return the numbers to 0, false to the boleys, so far dates, and regexps to empty (but Naoyen Naain will remain).  
 To continuously do this, maintain the object-valuable properties, but also emptying them (version 3):  
  function throoncate (obj) {for ( Var k in obj) {var ctor = obj [k] & amp; Amp; ; Obj [k] .constructor; If cut (ctor === object) (ojj [k]); Else if (ctor) obj [k] = ctor (); }}   
 To eliminate the number (version 2), add a check:  
  function in the threnetate (obj) {for (var k ) {Var Ctor = obj [k] & amp; Amp; Obj [k] .constructor; If cut (ctor === object) (ojj [k]); Else if (ctor === number) obj [k] remove; Else if (ctor) obj [k] = ctor (); }}

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

python - 'NoneType' object is not callable using 'find_all' in BeautifulSoup -

Here's my code using find_all, but this is my code. Works great with: (): To get beautiful suits R = requests from beautiful soup imports to import. (URL_DEFINED) Print Rustusodod Soup = Beautiful Soup (Rtext) Print soup.fund_all ('ul') What I found: Tracebacks (Most recent call end): File "scraper.py", line 1 9, & lt; Module & gt; Print soup.find_all ('ul') TypeError: The 'NoneType' object is not worth the corner It seems that you are using Sundersup version 3, in which a slightly different naming convention is used, such as: .findAll , while SunderSupo 4 standardized naming, like more PEP8, Such as: .find_all (but retains the old naming for previous compatibility) Note that soup ('ul') is equal to both search for all . To download and install, install pipes PrettySpeed ​​4 . Then to change your import: import from bs4 BeautifulSoup Then you are good go.
