DAY 1

    package hello  // package name hello   
    import (
        "fmt"
    )
    func Hello() {
        fmt.Println(" run if you can")
    }

Above code showed a ERROR : "go run: cannot run non-main package" due to package name is not main.

• To fix it, I just need to name the package to main. But I don't understand why I need to do that. I should be able to name the package whatever I want.
• Another question, I know main function is the entry point of the program, you need it. otherwise it will not work. But I see some codes that didn't have main function still works.
• Click on this link, the example at the bottom of the page didn't use package main and main function, and it still works. just curious

  WHY?

Resolving issue:

You need to specify in your app.yaml file what your app access point is. You need to specify

application: hello

refer to this link

-The entry point of each go program is main.main, i.e. a function called main in a package called main. You have to provide such a main package.
- GAE is an exception though. They add a main package, containing the main function automatically to your project. Therefore, you are not allowed to write your own.
