golang import all 类似python import * 效果

import "io/ioutil"

func main() { 
    content, err = iotuil.ReadFile("somefile.txt")
    // etc..
}

I guess this doesn't really answer your question, but if you want, you can actually call the methods without explicitly stating the package - just import with a . in front of the names (but this is not recommended; see below):

package main

import ( . "fmt" . "io/ioutil" ) func main () { content, err := ReadFile("testfile") if err != nil { Println("Errors") } Println("My file:\n", string(content)) }

Note @jimt's comment below - this practice is not advised outside of tests as it could cause name conflicts with future releases. Also, definitely agree with @DavidGrayson's point of being nicer to read/see where things come from.
