Do you want to assign names to your function arguments? Keyword arguments work like dictionaries, providing keyword names for the arguments passed to a function.
- [Instructor] Key word arguments are like…list arguments that are dictionaries instead of tuples.…This allows your function to have a…variable number of named arguments.…Here in Komodo, I've opened a working…copy of kwargs.py from chapter seven of the exercise files.…And you notice, down here on line seven, the function…argument has two asterisks in front of it…instead of one, as we had for the list arguments.…And it's named kwargs, which stands for key word arguments.…
And so when I run this, you'll notice that it says…Kitten Buffy says meow, Zilla says grr, Angel says rawr.…When we call the function, we have named…each of the arguments.…Buffy = 'meow', Zilla = 'grr', Angel = 'rawr.'…This is the same syntax as we used for dictionary.…And, in fact, this is a dictionary.…If I wanted to, I could say, x equals and dictionary…with those arguments, and then I can pass it x.…
And just as I would use one asterisk for a list,…I use two asterisks for passing at this dictionary,…and our result is exactly the same.…Again, it's traditional to name your…
