在Golang中Python的“id”函数的等价是什么?

python中id()是查看变量内存地址的。

golang中 &var &符号在变量前，还标识取地址。

@satoru发布:

package main

import "fmt"

func main() {
    i := 32
    j := 32
    fmt.Printf("%p is %p\n", &i, &i)
    fmt.Printf("%p is not %p\n", &i, &j)
}

输出:

0xc000016100 is 0xc000016100
0xc000016100 is not 0xc000016108

package main

import "fmt"

func main() {
    i := 32
    j := 32
    fmt.Printf("i %p is i %p; i == i %t\n", &i, &i, &i == &i)
    fmt.Printf("i %p is not j %p; i == j %t\n", &i, &j, &i == &j)

    fmt.Println()

    var v struct {
        i struct{}
        j struct{}
    }
    fmt.Printf("i %p is i %p; i == i %t\n", &v.i, &v.i, &v.i == &v.i)
    fmt.Printf("i %p is not j %p; i == j %t\n", &v.i, &v.j, &v.i == &v.j)
}

输出:

i 0x40e020 is i 0x40e020; i == i true
i 0x40e020 is not j 0x40e024; i == j false

i 0x1e52bc is i 0x1e52bc; i == i true
i 0x1e52bc is not j 0x1e52bc; i == j true
