IronPython is an open-source implementation of the Python programming language built on the .NET Dynamic Language Runtime, targeting Python 3 (currently Python 3.4 compatibility) with a Python 2.7 line also maintained. It lets Python code use .NET libraries and lets .NET applications embed Python as a scripting engine via NuGet.
Use cases
- embed a python scripting engine in a c# application
- call .net framework apis from python code
- expose python code to other .net languages
- script a .net application with python
- run python on the clr with .net standard support
When to choose
- you need tight interop between Python and .NET libraries
- you want to embed a dynamic scripting language in a .NET app
- you need Python on Windows/.NET Framework or .NET Core
When to avoid
- you need full modern Python 3.x compatibility (target is Python 3.4)
- you rely on CPython C extensions or the latest Python packages
- you need maximum Python performance
