Multivariable declaration//Multiple variables of the same type, non-global variables var vname1, vname2, vname3 = v1, v2, v3var vname1, vname2, vname3 = v1, v2, v3 //Similar to python, no need to display declaration type, automatically infer vname1, vname2, vname3:= v1, v2, v3 //Variables appearing on the left side of:= should not have been declared, otherwise it will lead to compilation errors//This factorization keyword is generally used to declare global variables var (var) vname1 v_type1 vname2 v_type2 Examples

package main

var x, y int

var ( //This factorization keyword is generally used to declare global variables

a int

b bool

)

var c, d int = 1, 2

var e, f = 123, "hello"

//This undeclared format can only appear in the body of a function

//g, h := 123, "hello"

func main(){

g, h := 123, "hello"

println(x, y, a, b, c, d, e, f, g, h)

}

The implementation results of the above examples are:
