[Tutor] STUPID telnet connection question

I think Steven and Alan misunderstood the Rayon's question. Rayon is using his telnet script to pass commands to a device ONE AT A TIME. Then he breaks the connection and reconnects for the next command.. He is asking how to open a telnet connection, pass MULTIPLE commands, then close the se

Re: [Tutor] search-replace

Or, open the file as a blob (one long string) and do a single 'replace'. fin = open("dirtyfile.txt", 'r').read().replace('## ', '#') open("dirtyfile.txt", 'w').write(fin) or, open("dirtyfile.txt", 'w').write(open("dirtyfile.txt", 'r').read().replace('## ', '#')) - Original Message --

Re: [Tutor] Making a script part of the terminal

I think I understand. One thing you can do is create a "myprogram.bat" file with an entry something like: python c:/myprogrampath/myprogram.py Put the "myprogram.bat" file in the root directory or any directory in the PATH. Then it will behave like an executable. In Linux, it would be "m

Re: [Tutor] create an xls file using data from a txt file

I'm not contradicting anyone, just relating my experience. I have a large suite of Python programs that run routinely on both Windows and Linux systems. Some of the programs build large directory tree structures. I cast all directory delimiters to the forward slash "/". No problems. -

Re: [Tutor] print "Hello, World!"

Seven years ago, my story was similar. I started off with "The Python Quick Book" (Manning) and "Python - Visual Quickstart Guide" (Peachpit Press). Both are very easy to follow. I still pick up the "Quick" book once in a while for reference. This "Tutor" list helped a lot. I learned by tryi

Re: [Tutor] Defining Exceptions

It's difficult to see exactly what the data looks like as it is received. Where are the line breaks? At the commas? Is the "header" just the first line? Is "1Time" considered part of the header? Is everything after "1Time" considered "data"? I can see several simple alternatives to your method

Re: [Tutor] Interactive visualization in python

FYI... There is a non-Python commercial program called XMLSpy which displays a visual tree rendition of an XML schema (.xsd) file. The schema file can be created or manipulated with Python/ElementTree. Maybe it can help you in your program development. - Original Message - Fro

Re: [Tutor] join question

"join" operates on lists. It "joins" the elements of the list using the leading character or string as the delimiter. In this case it is NUL. Try putting a character or string, like 'XX\n' in front of the ".join" in both places. It should illustrate what's really happening. "XX\n".jo

[Tutor] SSH session problems with network devices

Re: [Tutor] Seek suggestions for script for looking up extensions usingC:\>assoc

You wouldn't gain much with a Pyton script. You can specify the extension with "assoc". Try "assoc .zip". But if you want to try it anyway, look at the "popen2" module (depreciated) or the "subprocess" module to extract the data and assign it to a variable that you can parse any way you lik

Re: [Tutor] xml question

I agree with Steven D'Aprano. Keep the code as simple as possible. A simple text file with a variable/value pair on each line is very easy to parse and store in a Dictionary object. You can use any convenient delimiter; "=", ":", "$", ... Nesting items under categories takes just a little mo
