在Go中编写全局函数-类似于append（）

Question

The Question is simple - how can i implement a package independent global function in golang.

ID, if i have a function in an package called core then from another package i need core.Function() to call that function. But i In go implementation there are some functions like - make(), append() for slice that can used without any import and within any package directly. If i wanted to write function like this what is the way of doing this? how can i write any function like this if it is possible.

It's not possible to do exactly what you want but you can get somewhat close to it by using a dot-import. E.g. if you dot-import the fmt package, you can spell fmt.Println as just Println:

package main

import . "fmt"

func main() {
    Println("Hello, playground")
}
