I'm building a dictionary from a list with ~ 1M records.
Each record in the list is itself a list.
Each record in the list has a line number, (index 0) which I wish to use as
a dictionary key.
The problem: It is possible for two different records in the list to share
this line number. If they do,
*sigh* Ignore folks. I had forgotten about .has_key().

Lots of very good answers to a pretty stupid question! *blush*
I guess there is more than one way to do it!
Uh ... guys? Did I say something wrong...?

The difficulty I have may or may not be something that may be easily
handled with pyserial and some other mystery module.

I always slice the string in this sort of situation:
s = "12345678901234567890123456789012 "
t = s[:10],s[10:20],s[20:-1]
print t
('1234567890', '1234567890', '123456789012')
One could always bracket it to make a list or whatever.
Hope this helps!

I am in the middle of a project that requires me to send and retrieve

these:
1. I cannot send control characters
2. I cannot read data streaming from the serial port
I have been doing fine with:

I think I'm going to have to suck it up and learn some regular expressions.

Hi Andy,
Putting a try:/except: loop in your __main__() (or whatever you call
your base function) with sys.exit("Message") is pretty much the way I
always do it.

You can use a while loop in this case, but range() might be a bit more appropriate!
c = 0
d = raw_input("Enter Number Limit: ")
for i in range(int(d)): #note, we make sure "d" is an integer!
c = c + 1
