问题 I have this really convenient high-level pd.DataFrame saving function that I want to add to pandas . How can I add this method to the pd.DataFrame class? def to_file(df, path, sep="\t", compression="infer", pickled="infer", verbose=False, **args): _ , ext = os.path.splitext(path) # Serialization if pickled == "infer": if ext in {".pkl", ".pgz", ".pbz2"}: pickled = True else: pickled = False # Compression if compression == "infer": if pickled: if ext == ".pkl": compression = None if ext == "

问题 I need to compare two objects, and find out what properties are missing. The objects are fairly big, with several levels. I will give short example of the type of object: UC = {}; UC.start = {} UC.start.enableHardEccDecline = ''; UC.start.template = {}; UC.start.template.ecc = ''; UC.start.template.decline = {}; UC.start.template.decline.title = ''; UC.start.template.decline.body = ''; UC.general = {};... So this is an example object. What I need to compare is just the properties. I do not

问题 Following on from my previous thread, I went on to design the following Objects. /* --- LEAP Namespace --- */ var LEAP = {}; /* --- LEAP.Schedule Object --- */ LEAP.Schedule = function(){//init this.weeks = []; this.calculateWeeks(); }; LEAP.Schedule.prototype.pad = function (n) { return n>9 ? n : "0"+n; }; LEAP.Schedule.prototype.calculateWeeks = function(){ this.date = new Date ( 2011, 8, 5 ); // First week of new school year this.num = 36; // Calendar number of this week this.weeks.push

问题 I'm trying to remove objectst from an array which have 4 identical values and 1 unique. A quick google search gives a lot of options for removing identical objects from an array, but not objects that are similar . Example of array: var data = [ {Date: "2016-04-27T09:03:45Z", Name: "Tito", Title: "Developer", Department:"IT", Company: "XXX"}, {Date: "2016-04-27T08:07:45Z", Name: "Tito", Title: "Developer", Department:"IT", Company: "XXX"}, {Date: "2016-04-27T10:23:45Z", Name: "Tito", Title:

问题 The strange thing is that it works fine on my local deploy (Win 10 IIS) but when I deploy it to our UAT server, it goes nuts. I'm trying to deserialize the following json string: { "header": { "application-code": "ZZZ" }, "piece": [ "0000001" ] } The classes that represent this are defined: public class RequestPiece { [JsonProperty(PropertyName = "header")] public RequestHeaderPiece requestheader { get; set; } } public class ResponseHeaderPiece { [JsonProperty(PropertyName = "application-code

问题 This question already has answers here : How to use a variable for a key in a JavaScript object literal? (15 answers) Closed 3 years ago . I'm using Chrome's version of localStorage (chrome.storage.sync) and I want to use a variable key and value when setting what data to store with it. I'd like to be able to do something like this: chrome.storage.sync.set({ user: id }, callback); where the user and id are dynamically generated. This: var user = "Bob"; var id = "81256309"; chrome.storage.sync

问题 Take, for instance, the following object: var fruits = { "red" : "apple", "blue" : "blueberry", "yellow" : "banana" } I know I can use delete fruits["red"] to remove it by the key name, but how could I delete the object item by the fruit name? 回答1: Have you tried something like this? function deleteByValue(val) { for(var f in fruits) { if(fruits[f] == val) { delete fruits[f]; } } } And as per Rocket's comment, you might want to check hasOwnProperty to make sure you aren't deleting members of
