The simplest use case is using the subprocess.call function. It accepts a list as the first argument. The first item in the list should be the external application you want to call. The other items in the list are arguments that will be passed to that application. subprocess.call([r'C:\path\to\a...

For cases when we don't want to write special classes to handle some resource, we may write a generic class: template<typename Function> class Finally final { public: explicit Finally(Function f) : f(std::move(f)) {} ~Finally() { f(); } // (1) See below Finally(const Final...

Each enum class contains an implicit static method named values(). This method returns an array containing all values of that enum. You can use this method to iterate over the values. It is important to note however that this method returns a new array every time it is called. public enum Day { ...

Cloning a huge repository (like a project with multiple years of history) might take a long time, or fail because of the amount of data to be transferred. In cases where you don't need to have the full history available, you can do a shallow clone: git clone [repo_url] --depth 1 The above comman...

An algorithmic problem is specified by describing the complete set of instances it must work on and of its output after running on one of these instances. This distinction, between a problem and an instance of a problem, is fundamental. The algorithmic problem known as sorting is defined as follows:...

__CLASS__ magic constant returns the same result as get_class() function called without parameters and they both return the name of the class where it was defined (i.e. where you wrote the function call/constant name ). In contrast, get_class($this) and get_called_class() functions call, will both ...

int[] arr = new int[] { 0, 10, 20, 30}; // Get Console.WriteLine(arr[2]); // 20 // Set arr[2] = 100; // Get the updated value Console.WriteLine(arr[2]); // 100
