Hi Ole, Thanks for you kindly help. Now I know the data type mapping, and I have another question, When I pass parameters to a python api, the api excuted successfully, no error reported, but the final result is not what I want to get, So I want to debug to know where the issue existed, Does python api have debug mode to step in an python api internal to know the parameter that pass to the api is valid ?

Hi Yulong, Good question. That has been on my list of things to document for a while. Does https://gerrit.fd.io/r/#/c/19389/ answer your question? Please suggest improvements and improve the text as you notice gaps.
