python - Understanding control flow in traversing through list -


Here I have a class that uses a node and a function that prints the node in reverse order: 

  Category LLNode (object): def __init __ (self, data): '' '(LLNode, object) - & gt; None create a new node to hold '' 'type data self.data = data self.link = any def __str __ (self): return str (self.data) def reverse_list (L): If no one Returns head = L Tail = Head.link reverse_list (tail) print (head, end = '') list1 = LLNode (1) list1.link = LLNode (2) print (reverse_list (list1))  < / Pre> 
 I do not understand that when the  print  statement runs, because  is placed before the reverse_list (tail) , I think That look it I have been charged that if I change those two lines then the program will print the sequence in the link list, which I understand. How to reverse it after inserting  print  Prints in? I do not understand the flow here  
 
 Because  print  ing  After a recursive call, this happens when the calling function returns control,  back up  is a simple example here:  
  & gt; & Gt; & Gt; DEF RICKUR (X): print ("going down ({0})". Format (x)) if not x: print ("bottom hit") print ("Coming ({{}}" Format (x) Returns no recurrence (x-1) print ("Coming ({{}}". Format (x))> gt; & Gt; & Gt; Repeat (2) Going Down (2). Going down (1) are going down (0). The hit is coming down (0). Coming (1) Coming (2)

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
