go语言牛刀小试

1.部署go环境

docker pull golang:latest
docker run --name go-test -d golang:latest tail -f /dev/null
docker ps
docker exec -it go-test bash

2.编写go脚本

cat > go.go <<EOF
package main
import "fmt"
func main() {
    // float32
    // float64
    var (
        aaa      = "hello"
        sss, bbb = 1, 2
    )
    var a, b, c, d int
    a, b, c, d = 1, 2, 3, 4

    var e, f, g, h int = 1, 2, 3, 4

    i, m, n, o := 1, 2, 3, 4

    aa, _, cc, dd := 1, 2, 3, 4
    fmt.Println(aaa, bbb, sss, a, b, c, d, e, f, g, h, i, m, n, o)
    fmt.Println(aa, cc, dd)
}
EOF

3.执行go脚本

go run go.go
