This article mainly introduces a detailed explanation of Go string formatting example code. This article introduces you very detailed through the example code, which has certain reference value. Friends who need it can refer to it

Go provides good support for string formatting. Let's look at some common string formatting examples.

package main
import "fmt"
import "os"
type point struct {
  x, y int
}
func main() {
  // Go provides several print formats to format general Go values, for example  // The following %v prints the value of an object in a point structure  p := point{1, 2}
  ("%v\n", p)
  // If the formatted value is a structure object, then the formatted output of `%+v`  // will include the member name and value of the structure  ("%+v\n", p)
  // `%#v`Format output will output a Go syntax representation of a value.  ("%#v\n", p)
  // Use `%T` to output a value's data type  ("%T\n", p)
  // Format boolean variables  ("%t\n", true)
  // There are many ways to format integers, using `%d` is one  // Standard way of outputting integers in decimal  ("%d\n", 123)
  // This way outputs the binary representation of integers  ("%b\n", 14)
  // Print out the characters corresponding to the integer value here  ("%c\n", 33)
  // Use `%x` to output a hexadecimal representation of a value  ("%x\n", 456)
  // There are several formatting methods for floating-point values.  The most basic one is `%f`  ("%f\n", 78.9)
  // `%e` and `%E` use scientific notation to output integers  ("%e\n", 123400000.0)
  ("%E\n", 123400000.0)
  // Use `%s` to output basic strings  ("%s\n", "\"string\"")
  // To output a double quoted string like in Go source code, you need to use `%q`  ("%q\n", "\"string\"")
  // `%x` outputs strings in hexadecimal, and each string's bytes are output with two characters  ("%x\n", "hex this")
  // Use `%p` to output the value of a pointer  ("%p\n", &p)
  // When outputting numbers, you often need to control the width and accuracy of the output.  // You can use a number after % to control the width of the output, by default  // In case the output is right-aligned with spaces on the left  ("|%6d|%6d|\n", 12, 345)
  // You can also specify the output width of the floating point number, and you can also specify the floating point number  // Output accuracy  ("|%6.2f|%6.2f|\n", 1.2, 3.45)
  // To left-justify, use the `-` flag.
  ("|%-6.2f|%-6.2f|\n", 1.2, 3.45)
  // You can also specify the width of the output string to ensure that their output is aligned.  default  // In case, the output is right-aligned  ("|%6s|%6s|\n", "foo", "b")
  // To use left alignment you can precede the width with the `-` sign  ("|%-6s|%-6s|\n", "foo", "b")
  // The output of the `Printf` function is output to the command line`, you  // You can use `Sprintf` to assign the formatted string to a variable  s := ("a %s", "string")
  (s)
  // You can also use `Fprintf` to output the formatted value to ```  (, "an %s\n", "error")
}
