I'm working on a program named unitConversion.py. In it, I give the
user a chance to see a list of all the measurement units the program
handles, and their abbreviations. The user needs the abbreviations to
do the conversions. So I have a couple of functions (see below) that
together will print a list of unit abbreviations and their full names
(but not their respective categories). At this point there are 46
units, and that's a long list for the user to see if the printing is
done one unit per line. What I'd like to do is print the list in
maybe 3 neat columns. I'm sure this is possible, but after hours of
experimentation, I can't get a neat one to print. I know I could
stick a neat 3-column one in the script, but I'd like to learn how it
could be done with just the two functions
allUnitsAndTheirAbbreviationsAndCategories() and a modification of
printListOfAllUnitsAndAbbreviations().
BTW allUnitsAndTheirAbbreviationsAndCategories() is used elsewhere in
the program, so I don't want to change it, if possible.
Thanks very much,
Dick Moores
