## Наличие функции \* в определении функции

```Python
# How does *args work in a function definition 
 
 def hardFunc(arg1, arg2): 
    # create a tuple and pollute it with arguments passed to hardFunc 
    args=(arg1, arg2) 
    # print out results 
    print(args[0]) 
    print(args[1]) 
 
 hardFunc('hard_one', 'hard_two') 
 # output — Try it yourself now and in sequential snippets! 
 
 def softFunc(*args): 
    # at this point after calling softFunc a tuple with a name of a word 
    # followed by * is created automatically (in this case the name is args) 
    # print out results 
    print(args[0]) 
    print(args[1]) 
 
 softFunc('soft_one', 'soft_two') 
 
 # Now try to do something illegal 
 hardFunc('one', 'two', 'three') 
 
 # Now do things legally 
 softFunc('one', 'two', 'three') 
 
 # or even 
 softFunc('one', 'two', 'three', 'infinity') 
 
 # softFunc handles arbitrary amount of arguments easily by virtue of * syntax 
 # So using a single variable name in conjuction with * we gained the ability 
 # to invoke a function with arbitrary amount of arguments. 
 
 # Once again when softFunc is called the newly args 
 # tuple filled with provided arguments is created 
 
 # Conclusion softFunc is a more flexible/dynamic verson of a hardFunc
