If the value is a struct, the %+v variant will include the struct's field names:

fmt.Printf("%v\n", p)
fmt.Printf("%+v\n", p)

{10 200 3000}
{x:10 y:200 z:3000}

The %#v variant prints a Go syntax representation of the value, i.e. the source code snippet that would produce that value:

fmt.Printf("%#v\n", p)

main.point{x:10, y:200, z:3000}

To print the type of a value, use %T:

fmt.Printf("%T\n", p)

main.point

Formatting booleans, use %t:

var b bool
b = true
fmt.Printf("%t\n", b)

true

For integer, use %d for standard, base-10 formatting:

fmt.Printf("%d\n", 12335)

12345

binary representation of an integer, use %b:

fmt.Printf("%b\n", 9)

1001

To prints the character corresponding to the given integer, use %c:

fmt.Printf("%c\n", 89)

Y

%x provides hex encoding., use %x:

fmt.Printf("%x\n", 1501)

5dd

For float, use %f:

fmt.Printf("%f\n", 3.141592)

3.141592

%e and %E format the float in scientific notation:

fmt.Printf("%e\n", math.Pow(-9, 3))
fmt.Printf("%E\n", math.Pow(-9, 3))

-7.290000e+02
-7.290000E+02

For basic string, use %s:

fmt.Printf("%s\n", "string format")

string format

To double-quote a string, use %q:

fmt.Printf("%s\n", "quoted")
fmt.Printf("%s\n", "\"quoted\"")
fmt.Printf("%q\n", "\"quoted\"")

quoted
"quoted"
"\"quoted\""

As with integers seen earlier, %x renders the string in base-16, with two output characters per byte of input:

fmt.Printf("%x\n", "hex this")
fmt.Printf("%x\n", "h")
fmt.Printf("%x\n", "e")
fmt.Printf("%x\n", "x")
fmt.Printf("%x\n", " ")

To print a representation of a pointer, use %p:

fmt.Printf("%p\n", &p)
