How does IronPython handle conversions between Python types and .NET types?
IronPython runs on the .NET Framework which provides more primitive types than Python. If you use normal Python code with IronPython, you will only encounter the standard Python types (int, long, float, str, …). When calling .NET methods, IronPython will try to convert the argument values to the appropriate .NET types. See below for an example with integer numbers.
