On the surface, the input, output, and display of data is a simple process-the user enters data with a keyboard (or perhaps with a voice-recognition or handwriting-recognition engine), and the program displays that data using a selected font. To use formatted string literals, begin a string Given 'string' Each input represents a single argument. When we run the program, the output will be: The difference between ReadLine(), Read() and ReadKey() method is: If you want to know more about these methods, here is an interesting discussion on StackOverflow on: Difference between Console.Read() and Console.ReadLine()?. the repr() or str() functions. Your other method of output sharpening in Lightroom is designed for greater control when printing. As an example, the following lines produce a tidily aligned Let see different ways to display output using a format() method. With arrays, why is it the case that a[5] == 5[a]? Format String Syntax. left with zeros. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line?
