Python: variable parameters and apply

I think it is a relatively advanced usage in Python. I don't know if it is available in C. The special thing here is that since an interface has been made public, I cannot modify the function prototype, however, another function that accepts a parameter needs to pass the parameter it receives to a public function (of course, the data is correct). Therefore, you need to do so.

 #  ! /Usr/bin/ENV Python  #  -*-Coding: UTF-8 -*-  '''  A very advanced usage in Python: applyapply accepts two parameters: function pointers and meta groups (it seems that there are other more advanced usage). When applying calls a function executed by a function pointer, splits the tuples into parameter lists and passes them to the function.  '''  Import  Weburls = (  '  /App1  ' , '  App1  '  ,  '  /App2  ' , '  App2  '  ,  '  /App3/(\ W *)  ' , '  App3  ' ,  '  /App4/(\ W *)  ' , '  App4  ' , #  Agreed Interface  ) Web. config.
