Question

func execPython(fPath, colName, srv  string) (){
fmt.Println("Inside execPython")
cmd:= "python rfsvmchurn.py"
arg0 := "-fp " + fPath
arg1 := "-srv " + srv
arg2 := "-col " + colName

    fmt.Println("Python Execution Error :",err)
}

您的問題可能是您將標志及其參數作為單個字符串傳遞。 您應該改為：

func execPython(fPath, colName, srv  string) (){
    fmt.Println("Inside execPython")
    arg0 := "-fp " + fPath
    arg1 := "-srv " + srv
    arg2 := "-col " + colName
    cmd := exec.Command("python", "rfsvmchurn.py", "-fp", fPath, "-srv", srv, "-col", colName)
    if err := cmd.Run(); err != nil {
        fmt.Println("Python Execution Error :",err)
    }
}
