The elegance of Python

If I need a little utility and I'm running a Perl course, then I'll write it in Perl. Training in Tcl ... then that's the scripting language to use for other requirements that day (two languages in a day is too much). And of course if I'm running Python Programming it has to be .....

MY GOODNESS - what an elegant language Python is!



import os

have = os.listdir(".")

for fname in have:

    print "-" * 30,fname

    fh = open(fname,"r")

    for cline in fh.xreadlines():

        print cline,

That little script took all the examples I'd written into a directory and packaged them into a single file - bit of redirection and emailing, and all the trainees had a copy.

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
