Getting parameters of element in Cpython

@adarsh.bim there is also a workaround for this in cpython,
without the ironpython/cpython split - but it is surely not the prettiest:

[Bug]: cpython 3.8.5 shows "<class 'int'>" instead of "<class 'BuiltInParameter'>" enum member of BuiltInParameter

Bug

### ✈ Pre-Flight checks - [X] I **don't have SentinelOne** antivirus installed …(see above for the solution) - [X] I have **searched in the issues** (open and closed) but couldn't find a similar issue - [X] I have **searched in the [pyRevit Forum](https://discourse.pyrevitlabs.io)** for similar issues - [ ] I already **followed the [installation troubleshooting guide](https://pyrevitlabs.notion.site/Installation-issues-f6495adb56254e9e8021f8a68e3b2ab7) thoroughly** - [ ] I am using the **latest pyRevit Version** ### 🐞 Describe the bug When running these (apart from python3 shebang identical) snippets: in ironpython: ```python import clr clr.AddReference("Autodesk") from Autodesk.Revit.DB import BuiltInParameter as Bip import sys print(sys.version_info) print(sys.implementation.name) print("code: `type(Bip.LEVEL_IS_BUILDING_STORY)`") print(type(Bip.LEVEL_IS_BUILDING_STORY)) ``` and cpython ```python #! python3 import clr clr.AddReference("Autodesk") from Autodesk.Revit.DB import BuiltInParameter as Bip import sys print(sys.version_info) print(sys.implementation.name) print("code: `type(Bip.LEVEL_IS_BUILDING_STORY)`") print(type(Bip.LEVEL_IS_BUILDING_STORY)) ``` with pyrevit engines ironpython 3.4.0 and cpython 3.8.5 I get different type results: * on ironpython: `<class 'BuiltInParameter'>` (as expected) * on cpython: `<class 'int'>` (not as expected) this prevents me from using `level.get_Parameter(Bip.LEVEL_IS_BUILDING_STORY)` to access ui-language-agnostic parameter values for built-in-parameters. ![image](https://github.com/pyrevitlabs/pyRevit/assets/127405908/29bad07b-8671-457e-99de-dc1cd2d35cca) ### ⌨ Error/Debug Message ```shell if a parameter access is use with the above in cpython like so: doc = __revit__.ActiveUIDocument.Document print(doc.ActiveView.GenLevel.get_Parameter(Bip.LEVEL_IS_BUILDING_STORY)) the resulting error is as expected (it cannot find an overload with int as method argument): CPython Traceback: TypeError : No method matches given arguments for get_Parameter: (<class 'int'>) File "C:\ProgramData\pyRevit_BH\sandbox.extension\pyRevit_BH.tab\Sandbox.panel\Sandbox.pulldown\bip_test_cPy3_Sandbox.pushbutton\bip_test_cPy3_Sandbox_script.py", line 16, in <module> print(doc.ActiveView.GenLevel.get_Parameter(Bip.LEVEL_IS_BUILDING_STORY)) pyRevitLabs.PythonNet at Python.Runtime.Runtime.CheckExceptionOccurred() at Python.Runtime.PyScope.Exec(String code, IntPtr _globals, IntPtr _locals) at Python.Runtime.PyScope.Exec(String code, PyDict locals) at PyRevitLabs.PyRevit.Runtime.CPythonEngine.Execute(ScriptRuntime& runtime) # ------ I get the impression that in cpython we get the integer back from the BuiltInParameter Enum instead of the expected BuiltInParameter class object. ``` ### ♻️ To Reproduce 1. create new pyrevit button with the above snippets, for both ironpython and cpython. 2. run them and observe the different type output. ### ⏲️ Expected behavior receiving `BuiltInParameter` type for both python interpreter versions. ### 🖥️ Hardware and Software Setup (please complete the following information) ```shell * win 10 (19045) * rvt 2024 (24.1.0.66) * pyrevit 4.8.14 * ironpython 3.4.0 * cpython 3.8.5 ``` ### Additional context there is a discussion on the forum describing the same problem: https://discourse.pyrevitlabs.io/t/getting-parameters-of-element-in-cpython/3011 so far there is no solution mentioned there.

hopefully there will be a better way for this in future pyrevit cpython.
