I have a Python application that requires the
program be run in a specific folder, Win XP. It analyzes and modifies
txt files there, and only txt files. The mods require creating a tmp
file. The tmp files could just as well be an xyz suffix file. That is,
it seems as though they could be almost any non-conflicting type with
hundreds of file types in use. There may be other file types in the
folder, possibly jpg. As such, why would I want to use the tmp files
module?
With a similar program, it requires reading through all txt files,
among other files types, in the folder. It purely analyzes the data in
the txt files. Is there some way of doing the reading without the use
of os.listdir()?
I'm finding it a little hard to grok your question / concern.
One does not use os.listdir() to read files. One opens them then uses
read or readline.
There are many ways to get and filter directory contents.
I guess you would benefit from the glob module.
import glob
fileList = glob.glob('*.txt')
grok. An interesting word. I guess it means understand. Surprisingly
the Mozilla spell checker OKed it.
Anyway, I'm finally back. About one hour after posting this message, my
c-drive. Amazingly I got it back up.
Yes, listdir does not read files, it just prepares a list of all files
in the folder. I work my way through them as needed. It looks like glob
does something similar.
The real question is about tmp files. I believe there's a tmpfiles
module. Someone back a few weeks ago noted in a post I made that I was
using a tmp suffix and suggested using tmpfiles. In my case, I don't
see the need. What is the tmpfiles module going to do for me? What's so
special about the tmp suffix?

[Tutor] Python Working Environment, Checkout, Compare (diff), ...
Title: Signature.html Is there a Win Python environment that provides Linux like facilities like diff (compare) and checking in and out program files? For starters, I'm particularly interested in diff-ing two files. I'm modifying someone else's Python program and would like to see the line by line differences between what I now have and the original program. Is there some way I might be able to simply identity my code from the original? I suppose I could put a comment after every line, but that seems tedious. -- Wayne Watson (Watson Adventures, Prop., Nevada City, CA) (121.01 Deg. W, 39.26 Deg.

Re: [Tutor] Pyserial and general python serial help
Are you reading everything in the buffer? How much data is sent every 10ms? At 9600/8/N/1, the throughput is 960 byes a second, so if there's more than 9 bytes, something will give. Similarly, at 115200 baud, the limit is 115 bytes. Some general advice: don't try to sync your program to the 10ms cycle, that will be very difficult to do under a modern operating system. Just grab all the data waiting in the buffer and find some way to divide it into the appropriate time slices. PySerial has a method that returns the number of bytes in the buffer, so use that to set how many bytes you read.

[Tutor] return a dictionary?
Can I ‘return’ a dictionary from an imported Python script?
I have a utility module (NameAddress.py) done using Tkinter. (For example,
Name/Address City,State,Zip,Email, Phone) that I want to use as imported
module. I wanted to return the values as a dictionary to the module that
imported but this does not seem to work.
This is the dictionary as printed out from the NameAddress.py by print theDict
shows what I want:
{'City': 'San Francisco', 'Name': 'Sam Spade', 'Zip': '98765', 'Address1':
'Apt. #87', 'Address2': '2345 Union Street', 'Phone': '1-415-896-9876',
'State': 'Ca.', 'Email': '[EMAIL PROTECTED]'}
However the code for return in NameAddress.py , I.E. return theDict
gives this error when called from a testing module (Inter_module.py) whose
code looks like this:
import NameAddress
y = NameAddress.getName()
print y
Traceback (most recent call last):

This looks like an error in NameAddress.py, perhaps something that is
not being initialized correctly when you import it? Do you have a
if __name__ == '__main__':
section in NameAddress.py? Does it do some required initialization?
It sounds like you are doing something similar to EasyGui's multienterbox:
