| Relationships between * and args | العلاقات بين * و args |
وجود * في تعريف الوظيفة
`# 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
