Could not import module written in c# with IronPython

Question

Currently i'm struggeling with writing IronPython modules in c#. At first i have some empty partial class, which represents the module base:

[assembly: PythonModule("demo", typeof(Demo.IronPythonAPI.PythonAPIModule))]
namespace Demo.IronPythonAPI
{
    /// <summary>
    /// Demo api module root/base
    /// </summary>
    public static partial class PythonAPIModule
    {

    }
}

In some other files, i try to implement the modules:

namespace Demo.IronPythonAPI
{
    /// <summary>
    /// Python api module path root (~import demo)
    /// </summary>
    public static partial class PythonAPIModule
    {
        /// <summary>
        /// Python SQL-Module
        /// </summary>
        [PythonType]
        public static class Sql
        {
            public static int executeNoneQuery(string query, string conName)
            {
                Console.WriteLine("Hello World");

                return 0;
            }
        }
    }
}

If i now want to use the module, it does not work:

import demo
Sql.executeNoneQuery("", "")

This throws the exception:

name 'Sql' is not defined

When using

from demo import Sql
Sql.executeNoneQuery("", "")

Everything works just fine. What did i do actualy wrong?

Thank you very much!

You should check the difference between import and from import

Demo.Sql is needed in the first case. So try Demo.Sql.executeNoneQuery("", "") instead

Ok, this makes sense. If IP would do it as i expected it, `import Demo` would be the same as `from Demo import *`, or not? – BendEg Dec 29 '15 at 14:35
