Python : *args vs **kwargs

def printFunc(arg1, *argv): 
    print ("Argument via argv1 :", arg1) 
    for arg in argv: 
        print("Argument via *argv :", arg) 
  
printFunc('Hello', 'this', 'is', 'Debaditya') 

>> First argument : Hello
Argument *argv : this
Argument *argv : is
Argument *argv : Debaditya

def printFunc(arg1, arg2, arg3): 
    print("arg1:", arg1 ) 
    print("arg2:", arg2) 
    print("arg3:", arg3) 
      
args = ("This", "is", "Debaditya") 
printFunc(*args) 
  
kwargs = {"arg1" : "This", "arg2" : "is", "arg3" : "Debaditya"} 
printFunc(**kwargs)
