Golang import package inside package

Question

Go structure:

|--main.go
|
|--users
     |
     |---users.go

The two files are very simple: main.go:

package main

import "./users"

func main() {
    resp := users.GetUser("abcde")
    fmt.Println(resp)
}

users.go:

package users

import "fmt"

func GetUser(userTok string) string {
    fmt.Sprint("sf")
    return "abcde"
}

But it seems fmt is not accessible in main.go. When I try to run the program, it gives

undefined: fmt in fmt.Println

Anybody knows how to make fmt accessible in main.go?

Go, is based on "has a" relationship, hence when using users in main, fmt package from users is not available to main and need to be imported explicitly in main. — Prashant Thakkar

You shouldn't use relative import paths if you want the standard build tools to work with your project. — Mr_Pink

You need to import fmt in main as well.

Simply write "fmt" in import() in main.go and it should run.

import(    
    "fmt"  
    "./users"
)
