course, in the 1990s. Idiomatic lang, i.e. lang with huge number of
bizarre idioms, such as perl, is the worst.

Dear Xah, your writing is:

Thanks for the fix.
Though, it seems still wrong.
On the file http://xahlee.org/p/time_machine/tm-ch04.html
there is a mismatched curly double quote at 28319.
the script reports:
tm-ch04.html: bad ')' at 68:2
that doesn't seems right. Line 68 is empty. There's no opening or
closing round bracket anywhere close. Nearest are lines 11 and 127.
Maybe Billy Mays's algorithm is wrong.

are you willing to make it complete and standalone? i.e. i can run it
like this:
perl Rouslan_Korneychuk.pl dirPath
and it prints any file that has mismatched pair and line/column number
or the char position?
i'd do it myself but so far i tried 5 codes, 3 fixes, all failed. Not
a complain, but it does take time to gather the code, of different
langs by different people, properly document their authors and
original source urls, etc, and test it out on my envirenment. All
together in the past 3 days i spent perhaps a total of 4 hours running
several code and writing back etc and so far not one really worked.
i know perl well, but your code is a bit out of the ordinary ☺. If
past days have been good experience, i might dive in and study for
fun.

hi Chris,
i created a page dedicated to creating math symbol layouts for
different langs.
I linked to your post.
I wonder if you would let me mirror your X code on my site? Or, if you
place it on somewhere more permanent or dedicate page such as git, i'd

Sort a List
Xah Lee, 200510
In this page, we show how to sort a list in Python & Perl and also
discuss some math of sort.
To sort a list in Python, use the “sort” method. For example:
li=[1,9,2,3];
li.sort();
print li;
Note that sort is a method, and the list is changed in place.

Python Doc Problem Example: sort()
Xah Lee, 200503
Exhibit: Incompletion & Imprecision
Python doc “3.6.4 Mutable Sequence Types” at
http://python.org/doc/2.4/lib/typesseq-mutable.html
in which contains the documentation of the “sort” method of a list.

latch on of “multiple passes” and the mysterious “by department,
by salary”.
Here's a suggested rewrite: “Since Python 2.3, the result of sort()
no longer rearrange elements where the comparison function returns
0.”

languages and its people. In Python, the language syntax is tainted. In
Perl, a complex construct is invented. In both camps, the basic
mathematics of sorting and its implementation aspects are completely
belied.
For the official doc of Perl's sort, type on the command line:
“perldoc -f sort”.

The Python doc really should mention it at the place where the sort
method is documented.

Microsoft Hatred, FAQ
Xah Lee, 20020518
Question: U.S. Judges are not morons, and quite a few others are
not morons. They find MS guilty, so it must be true.
Answer: so did the German population thought Jews are morons by
heritage, to the point that Jews should be exterminated from earth
list?
Thanks.

Split File Fullpath Into Parts
Xah Lee, 20051016
Often, we are given a file fullpath and we need to split it into the
directory name and file name. The file name is often split into a core
part and a extension part. For example:
'/Users/t/web/perl-python/I_Love_You.html'
becomes

Thanks for the note. I've corrected it here:

i think the function shouldn't complain if dir already exists. How is a
programer to distinguish if the dir already exists, or if there's a
problem creating the dir?

One-Liner Loop in Functional Style
Xah Lee, 200510
Today we show a example of a loop done as a one-liner of Functional
Programing style.
Suppose you have a list of file full paths of images:
