I'm using notepad2 as my editor now and got it set to not indent
automatically and let it number the lines. That way if it says error on line
blah blah blah, I can just go straight to it.

I agree, get used to indenting all code.  That is the way programming is 
done and it actually helps you think in terms of code blocks.

And your screen reader can announce indent levels changes to remind you.

While PyBraces and similar is a generally good idea, I strongly
recommend actually getting familiar with the indentation scheme of Python.
As David wrote, this is generally quite simple with a screen reader. It
has many benefits:
• It allows you to code anywhere with Python installed, a far greater
subset of computers than that with both Python and PyBraces installed.
• When writing in languages which use braces for scope control, such as
C, Java, C++, whatever, indentation is still important. If you're
working on code that you're sharing with sighted people, the expectation
will be that you indent. Python gets you into this habit.
• Using indentation alone is generally more efficient for communicating
information to a blind person. Observe:

def do_something(arg1, arg2): {
assert ([isinstance(i, (int, long)) for i in arg1, arg2])
if arg1 < arg2: {
#Take an action here
else: {
#Do something else here

Compare to:

def do_something(arg1, arg2):
(one space.) assert ([isinstance(i, (int, long)) for i in arg1, arg2])
if arg1 < arg2:
(2 spaces.) #do something here
(one space.): else:
(two spaces.) #Something else

I placed in leading parentheses the text which is spoken by the screen
reader as you navigate from line to line. Note that if two lines are on
the same indentation, the indentation will not be announced. Which makes
it really trivial to actually spot where indentation changes.
Compare to braces, where you have to keep in your head not only code
scope, but what braces go with what, as well as brace matching heuristics.
When working in a braced language, I often use comments to indicate what
the closing brace signifies. For instance } //Endif, } //end function
do_something. This is simply something which is unnecessary when reading
an indented language.

In short, spend the slight extra time to do it right, and you'll reap
the benefits, just like most other things in life, and especially

I welcome your thoughts and feedback,
