Additionally, Println also accepts multiple arguments, separated by a comma, while Print only accepts a single argument. On the other hand, if you use Print, all the values will be printed on the same line, separated by a space character. This means that if you use Println to print multiple values, each value will be printed on a new line. The main difference between them is that Println adds a newline character at the end of the output, while Print does not. In Go, the Print and Println functions are used to print output to the console. The variables are passed to Printf() as arguments in the order that they should appear in the output string.ĭifferences between Print and Println functions The %v verb is used to represent the value of the variables name and age. We then use Printf() to print them as part of a sentence. In the example above, we declare two variables age and name. Output: My name is John and I am 25 years old. Here is an example of the Print function in action:Įnter fullscreen mode Exit fullscreen mode The Print function is useful for quickly printing a value or a set of values to the console for debugging purposes. If you want to use a different separator, you can use the Println function instead, which uses a newline character as the separator. The Print function takes zero or more arguments of any type and concatenates them into a string using spaces as separators, and then writes the resulting string to the standard output. The Print function in Go is a built-in function that allows you to print to the standard output (usually the console). We will also go on to explain the differences between the two functions and how they can be used to output strings, numbers, and variables. In this article, we will explain the importance of printing in programming and how Go provides two built-in functions, Print and Printf, for this purpose. The Print() and Printf() functions also accept multiple arguments, which are printed separated by spaces. These placeholders start with a percent sign (%), and the letter after the percent sign indicates the type of value to be replaced. The format string in Printf() can contain placeholders, which will be replaced with the values provided as arguments. The Print() function simply prints the text on the screen, while Printf() allows us to format the text before printing. The fmt package provides two main functions for printing: Print() and Printf(). In Go, printing is done through the fmt package, which is part of the standard library. Printing is the most basic way of displaying information on a computer screen.
