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!


Answer: You should check the difference between **[import and from
import](http://stackoverflow.com/questions/710551/import-module-or-from-
module-import)**

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