what is `"%#v"` in go

"%#v" is a formatting verb used in Go to print a Go-syntax representation of a value. It is similar to the "%v" verb, but it includes type information and additional formatting details.

Here's an example to demonstrate the usage of "%#v":

main.go
package main

import "fmt"

type Person struct {
    Name string
    Age  int
}

func main() {
    john := Person{Name: "John", Age: 25}
    fmt.Printf("%#v\n", john)
}
169 chars
14 lines

Output:

main.go
main.Person{Name:"John", Age:25}
33 chars
2 lines

As you can see, the %#v verb prints a representation of the john variable in Go-syntax format, including the struct type and field names.

This can be useful for debugging or when you need a detailed representation of a value.
