I like to use properties in a class instead of methods, since they look more enum-like. Here's an example for a Logger: public class LogCategory { private LogCategory(string value) { Value = value; } public string Value { get; private set; } public static LogCategory Trace { get { return new LogCategory("Trace"); } } public static LogCategory Debug { get { … [Read more...]

What you have should work. If, however, the spaces provided are defaulting to... something else? You can use the whitespace regex: str = "Hello I'm your String"; String[] splited = str.split("\s+"); This will cause any number of consecutive spaces to split your string into tokens. As a side note, I'm not sure "splited" is a word :) I believe the state of being the victim of a … [Read more...]

When you run a program in python, the interpreter compiles it to bytecode first (this is an oversimplification) and stores it in the __pycache__ folder. If you look in there you will find a bunch of files sharing the names of the .py files in your project's folder, only their extensions will be either .pyc or .pyo. These are bytecode-compiled and optimized bytecode-compiled … [Read more...]

Each YouTube video has four generated images. They are predictably formatted as follows: https://img.youtube.com/vi//0.jpg https://img.youtube.com/vi//1.jpg https://img.youtube.com/vi//2.jpg https://img.youtube.com/vi//3.jpg The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (i.e., one of 1.jpg, 2.jpg, 3.jpg) … [Read more...]

pip is run from the command line, not the Python interpreter. It is a program that installs modules, so you can use them from Python. Once you have installed the module, then you can open the Python shell and do import selenium. The Python shell is not a command line, it is an interactive interpreter. You type Python code into it, not commands. Use the command line, not the … [Read more...]

When you make a POST request, you have to encode the data that forms the body of the request in some way. HTML forms provide three methods of encoding. application/x-www-form-urlencoded (the default) multipart/form-data text/plain Work was being done on adding application/json, but that has been abandoned. (Other encodings are possible with HTTP requests generated using other … [Read more...]

TL;DR Summary; if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data. Otherwise, use application/x-www-form-urlencoded. The MIME types you mention are the two Content-Type headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of … [Read more...]

There is an ordered set (possible new link) recipe for this which is referred to from the Python 2 Documentation. This runs on Py2.6 or later and 3.0 or later without any modifications. The interface is almost exactly the same as a normal set, except that initialisation should be done with a list. OrderedSet([1, 2, 3]) This is a MutableSet, so the signature for .union doesn't … [Read more...]
