The byte and bytearrays are used to manipulate binary data in python. These bytes and bytearrys are supported by buffer protocol, named memoryview. The memoryview can access the memory of other binary object without copying the actual data. The byte literals can be formed by these options. b‘This is bytea with single quote’ b“Another set of bytes with double quotes” b‘’’Bytes using three single quotes’’’ or b“””Bytes using three double quotes””” Some of the methods related to byte and bytearrays are − Method fromhex(string) The fromhex() method returns byte object. It takes a string where each byte is ... Read More
The sets are basically an unordered collection of distinct hash-table objects. We can use the set for some mathematical operations like set union, intersection, difference etc. We can also use set to remove duplicates from a collection. The set do not record the element position. It does not support the indexing, slicing or other sequence related operations. In python there are basically two types of sets. The set and the frozenset. The set type is mutable, whether the frozenset is immutable. We can perform add(), remove() and these kind of operations on set, but it is not possible for frozenset. ... Read More
Google Analytics is a freemium analytic tool that provides a detailed statistics of the web traffic. It is used by more than 60% of website owners. Analytics Tools offer an insight into the performance of your website, visitors’ behavior, and data flow. These tools are inexpensive and easy to use. Sometimes, they are even free.If the application is offline, Google Analytics stores the events in an SQLite database.After storing, it waits until the user is online again to send them.It is used to collect offline latent hits. The value represents the time delta in milliseconds between when the hit occurs ... Read More
The python operator performs very badly in a list, O(n), because it traverses the whole list. You can use something like a set or a dict(hashed data structures that have very fast lookups) to get the same result in ~O(1) time!But this also depends on the type of data structure you're looking at. This is because while lookups in sets/dicts are fast, insertion may take more time than list. So this speedup really depends on the type.
You can handle it by creating an array and insert an object into Array. Bapisdhd1 order_header_in = new Bapisdhd1(); order_header_in.DocType = "OR"; order_header_in.CollectNo = "111022"; order_header_in.SalesOrg = "11011"; order_header_in.DistrChan = "100"; order_header_in.Division = "000"; order_header_in.DlvBlock = "010"; order_header_in.PurchNoC = "TEST ORDER"; newOrder.OrderHeaderIn = order_header_in;
Yes, the constructor should always have the same name as the class. Constructor looks like method but it is not. It does not have a return type and its name is same as the class name. Mostly it is used to instantiate the instance variables of a class. If the programmer doesn’t write a constructor the compiler writes a constructors on his behalf. Example Live Demo public class Sample{ public Sample(){ System.out.println("This is a constructor"); } public static void main(String args[]){ Sample obj = new Sample(); } } Output This is a constructor
For expressions like − a == b first the python interpreter looks up the __eq__() method on the object a. If it finds that, then executes that with b as argument, ie, a.__eq__(b). If this method returns a NotImplemented, then it tries doind just the reverse, ie, it tries to call, b.__eq__(a)
Client-side XSLTProcessor API is part of the HTML5 scripting specification, as stated below:When an XSLT transformation program is triggered by a processing instruction and the browser implements a direct-to-DOM transformation, script elements created by the XSLT processor need to be marked "parser-inserted" and run in document oThe XSLTProcessor.transformToDocument() method adds elements to a Document that does not have a browsing context, and, accordingly, any script elements they create need to have their "already started" flag set in the prepare a script algorithm and never get executed (scripting is disabled). Such script elements still need to be marked "parser-inserted", though, such ... Read More
Here are some of the steps that you can follow to optimize a nested if...elif...else.1. Ensure that the path that'll be taken most is near the top. This ensures that not multiple conditions are needed to be checked on the most executed path.2. Similarly, sort the paths by most use and put the conditions accordingly.3. Use short-circuiting to your advantage. If you have a statement like:if heavy operation() and light operation():Then consider changing it toif lightOperation() and heavy operation():This will ensure that heavy operation is not even executed if the light operation is false. Same can be done with or ... Read More
Ionic is an HTML5 Mobile App Development Framework targeted at building hybrid mobile apps. Think of Ionic as the front-end UI framework that handles all the look and feel and UI interactions your app needs to be compelling. Kind of like "Bootstrap for Native", but with the support for a broad range of common native mobile components, slick animations and a beautiful design. Ionic framework needs native wrapper to be able to run on mobile devicesIonic is built and tested for mobile only. Internet Explorer does not support all the features of Ionic. Use separate applications for desktop and mobile. However, you ... Read More
