This question already has an answer here:
So I have difficulty with the concept of *args and **kwargs.
So far I have learned that:
*args = list of arguments - as positional arguments**kwargs = dictionary - whose keys become separate keyword arguments and the values become values of these arguments.I don't understand what programming task this would be helpful for.
Maybe:
I think to enter lists and dictionaries as arguments of a function AND at the same time as a wildcard, so I can pass ANY argument?
Is there a simple example to explain how *args and **kwargs are used?
Also the tutorial I found used just the "*" and a variable name.
Are *args and **kwargs just placeholders or do you use exactly *args and **kwargs in the code?
