Go: Emulate ssh remote execution of local script with arguments in golang

I'm trying to execute anytype of local script(sh/bash/python/ruby) or executable with arguments to a remote machine using go.
ssh command: ssh [email protected] "python3" - < ./test.py "arg1"

package main
import (
    "log"
    "os"

    "golang.org/x/crypto/ssh"
)

func main()  {
    user := "user"
    hostport := "10.10.10.10:22"
    script, _ := os.OpenFile("test.py", os.O_RDWR|os.O_CREATE, 0755)
    interpreter := "python3"
    client, session, err := connectToHost(user, hostport) 
    session.Stdin = script
    session.Stdout = os.Stdout
    err = session.Run(interpreter)
    if err != nil {
        log.Fatal(err)
    }
    client.Close()
    defer session.Close()
}

The example ssh command is working fine and I'm able to execute the local test.py in the remote server too, but I can't think of any efficient way which will help me to pass arguments(ex. arg1) as well.
Thanks for the help.

Why not just pass the flags to the python file? By using the less-than symbol, you're literally inputting the output of test.py into the Go executable. 

ssh [email protected] "python3" - < ./test.py <flag1> "arg1" <flag2> "arg2"

Unless I'm fundamentally misunderstanding what you're trying to do?
