Python exercises a record function to run the adorner

1. Write an adorner to see when the function executes

Import datetime
Import time
def jishi (fun):
   Def warper ():
      Start_time = Datetime.datetime.now ()
      Fun ()
      End_time = Datetime.datetime.now ()
      Haoshi = (end_time-start_time). Total_seconds ()
      Print ("function run time {}". Format (Haoshi))
   Return Warper ()

@jishi
Def Yunsuan ():
   Time.sleep (2)
   For x in range (100):
      Print (x)
Yunsuan ()


Summary: The general idea is to use local time after the function is run minus the local time before the function is run. about why the adorner is nested in a double function, because the adorner is meant to be the code and invocation of the original function, so it requires warper to be encapsulated together with the original function and the added functionality.

return together.
