I install RFC SDK at C:\nwrfcsdk and already add C:\nwrfcsdk\lib in system environment but when I run application on IIS , the system displays
DLL load failed: The specified module could not be found so I tried to move the file sapnwrfc.dll to C:\Python27\Lib\site-packages\pyrfc and system shows error the same message as above (HTTP Error
500.0 - Internal Server Error)
I guess IIS can't connect to package from C:\nwrfcsdk\lib but I already add full permission to that folder ( IUSER )
Could you share C:\nwrfcsdk\lib folder permission and iis application pool snapshot?

and I have granted access IUSER and IIS_IUSER for python folder , site folder with full permission and I don't know how to grant access for application pool
When you enable, you capture status code from 200-500 so all the request will be logged. Then you can try accessing the site and check what is wrong by checking FREB traces.

If PyRFC crashed Python processes, you should report to SAP, not here,

I think not PyRFC crashed because when I run in localhost it work fine. but run on IIS it crashed may be IIS can't find module Pyrfc
then I want to know how to add to pyrfc package to IIS (RFC SDK install at C:\nwrfcsdk )

Select the application pool and then select iis application pool advance setting.
In advance setting check application pool identity:
Try to use Process Monitor to monitor w3wp.exe IIS worker process and python.exe after calling the API.
dependency walker to track the dependent dll.

Now I have moved the sapnwrfc.dll file to C:\Python27\Lib\site-packages\pyrfc\sapnwrfc.dll and system found it
Then I look at procmon again and find path C:\Python27\Lib\site-packages\pyrfc\sapnwrfc.dll.
Procmon show FILE LOCKED WITH ONLY READERS at Results column
https://imgur.com/H5ZBv4L
and result on web browser display error internal 500 when I call pyrfc connect function then I will look at permission on C:\Python27\Lib\site-packages\pyrfc\sapnwrfc.dll it have full permission
(sapnwrfc.dll permission )

You could give application pool permission to the folder by:
IIS AppPool\<myappoolname>
Please provides application pool identity setting as suggested in this step:
https://forums.iis.net/post/2149169.aspx
Also, run FRT in iis :
https://docs.microsoft.com/en-us/iis/troubleshoot/using-failed-request-tracing/troubleshooting-failed-requests-using-tracing-in-iis#enable-failed-request-tracing
When you enable, you capture status code from 200-500 so all the request will be logged. Then you can try accessing the site and check what is wrong by checking FREB traces.
