最简单的方法/在go中声明变量的简写

Question

We can use the following syntax for go variable declaration

var num int
var str string

but is there any shorthand in go for doing the same thing?

for example we can do so in python simply saying:

num = 13
strings = "Hello World"

or even

num, strings = 13,"Hello World" 

Answer 1

The variable declaration can initialize multiple variables:

var x, y float32 = -1, -2

Or (short variable declaration with :=)

i, j := 0, 10

So this would work: play.golang.org

package main

import "fmt"

func main() {
    a, b := 1, "e"
    fmt.Printf("Hello, playground %v %v", b, a)
}

Output:

Hello, playground e 1
