There are (were?) operating systems that could only deal with a maximum
length for pathnames. If I recall correctly, and I probably don't, Classic
Mac (pre-OS X) was limited to file names of 31 or fewer characters and no
more than 250-odd for the entire pathname. At the very least, some file
manager routines would work and some would not.

If you are printing the pathname, you may care about the length so that
you can truncate it:

longname = "C:\really\really\really\really\really\long\path\name.txt"
if len(longname) > 30:
    # do magic here
    print "C:\really\ ... \path\name.txt"
else:
    print longname
