Using a dictionary as an argument when calling tuple()

my_tuple = tuple({'ny': {'yankees', 'mets'}, 'la': 'dodgers'}) results in ('ny', 'la') when I run this in the Python Shell. Why is this result the result that comes back? Also, how can I insert code snippets when asking questions?

Perhaps this will do what you want:

my_tuple = tuple({'ny': {'yankees', 'mets'}, 'la': 'dodgers'}.items())

If that's not it, please indicate what you expect to get from the conversion.

And for posting code like I have done here, just copy/paste and use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.

Thanks for responding Steven. When I watched the video Introduction to Tuples, Kenneth used a list for an argument within the tuple function such as in tuple([1, 2, 3]) so I just wondered what would happen if a dictionary was passed instead as in my_tuple = tuple([1, 2, 3]) which returns (1, 2, 3).

I went into the REPL in workspaces by typing just python and entered my_tuple = tuple({'ny': {'yankees', 'mets'}, 'la': 'dodgers'}) and was just wondering why when I enter my_tuple again in the REPL that I get a result of ('ny', 'la') that is just a tuple of the keys?

Yes, by default you get just the keys. Use the ".items()" method to get the values as well.
