Here's how I fixed that problem: https://github.com/GrantEdwards/hybrid-inews I read this "group" using slrn pointed at gmane.comp.python.general, on the NNTP server news.gmain.io. When I post to this group from slrn, it gets e-mailed to the regular mailing list address. Other gmane "groups" get posts sent via NNTP. slrn is configured to post all articles via /usr/local/bin/inews (which is the python "inews" work-alike program above) when connected to news.gmane.io.

The `pprint` module (which has `pprint` and `pformat` functions) outputs Python notation. If you're just writing for human eyes, JSON is fine, though you will want to keep in mind that JSON spells `None` as `null`.

If you want tables layed out in a framing grid, you might want to take a look at this: https://bitbucket.org/astanin/python-tabulate/pull-requests/31/allow-specifying-float-formats-per-column/diff Frederic On 6/9/22 12:43, Dave wrote: Hi, Before I write my own I wondering if anyone knows of a function that will print a nicely formatted dictionary?

Re: Function to Print a nicely formatted Dictionary or List?
Dave, Despite your other programming knowledge, I suspect you think this is the forum where people come to be tutored. Try here: https://mail.python.org/mailman/listinfo/tutor Yes, there are plenty of pretty printers available and you can build your own function fairly easily. A module like pprint may have what you want in pprint.pprint() but you can write a function for yourself that takes a dictionary and loops through items and prints them one per line and, if you feel like it, also prints how many items there are and your own custom touches such as doing them alphabetically. Consider using a search engine before posting. Throw in a few words like "python pretty print dictionary function" and refine that if it does not get you immediate results. It is free and easy and does not waste time for so many others who already know or don't care. And consider reading a few books perhaps designed to teach python to people with some programming experience or taking a course on something like COURSERA as a part of your learning process and not depending on volunteers so much. Much of what you are asking is covered in fairly beginner and intermediate such books/courses. I think I am now going to ignore messages from you for a while.
