Did you read the rest of his post? He's using a screen reader for a
reason; he can't *see* the code. visual means of structuring code like
whitespace are meaningless to him at best, and annoying at worst. No
wonder his code is littered with '#end def' comments. Python's
significant indentation is horrible for the blind, at least until we
create a more specialized/better screen reader.
Alex, Perhaps a better solution is to indent with tabs rather than
spaces, though I'm normally opposed to using tabs. Alternatively, run
your files through a script that expands every indent space to four
spaces before posting here. I've attached a bare-bones script that
takes a file and a number as argument, replaces every initial space
with that number of spaces, and writes the result to a new file
(filename is just the old filename with .new appended).
Yes, the script is indented with four spaces, Sorry. I'm sure you
could write a script that does the reverse operation so it becomes a
little more readable for you.

#! /usr/bin/env python
import sys

"""replace every initial space in string with num spaces"""
if string[0] == ' ':
return (' ' * num) + expand_indent(string[1:])
else:
return string
if __name__ == '__main__':
if len(sys.argv) == 3:
num = int(sys.argv[2])
else:
num = 4
infile = open(sys.argv[1], 'r')
outfile = open(sys.argv[1] + '.new', 'w')
for line in infile:
outfile.write(expand_indent(line, num))
infile.close()
outfile.close()
