How do I check for EOF in Python? I found a bug in my code where the last block of text after the separator isn't added to the return list. Or maybe there's a better way of expressing this function? Here's my code: def get_text_blocks(filename): text_blocks = [] text_block = StringIO.StringIO() with open(filename, 'r') as f...
I am building a website where I have a need that user should be able to evaluate some expression based from the value in DB tables, instead of using tools like pyparsing etc, I am thinking of using python itself, and have come up with a solution which is sufficient for my purpose. I am basically using eval to evaluate the expression and ...

My app must read an SSL url from a third party. How do I best store the third party credentials in my own database, which protects the third party credentials from being compromised? Consider both absolute security and practicality. One-way hashing the credentials is not useful as I must restore credentials to plaintext for the SSL call....

I'm thinking about good ways to store third party credentials, which basically means there needs to be a secret somewhere, either in code or data. I'm deploying on google app engine. If the 'secret' was something like pw_passphrase = sha2(username + 'global-password') pw_plaintext = aes_decrypt(pw_passphrase, pw_ciphertext) can I dep...

I use grep to parse through my trading apps logs, but it's limited in the sense that I need to visually trawl through the output to see what happened etc. I'm wondering if Perl is a better option? Any good resources to learn log and string parsing with Perl? I'd also believe that Python would be good for this. Perl vs Python vs 'grep o...

Python seems to have functions for copying files (e.g. shutil.copy) and functions for copying directories (e.g. shutil.copytree) but I haven't found any function that handles both. Sure, it's trivial to check whether you want to copy a file or a directory, but it seems like a strange omission. Is there really no standard function that w...

I found that after submiting, if a browser back-button is pressed (IE8, Firefox) unlike regular HTML Textarea, I return to the input screen, but the Textarea is EMPTY. What I would like to happen is that after back-button is pressed, I would return to ...

I'm having a problem reading and processing data from my server. I've spent hours debugging this and it seems as though the problem has nothing to do with the server but is really just an issue with one of my for loops. Its difficult to explain this without actually seeing the data from the server, but I'll do my best to explain this. B...

Hi, I've always thought about creating my own ftp client ever since I've started using the Internet. And now that I'm studying Python, I'm thinking about creating one as an exercises/personal project. I'm wondering, what libraries do you guys suggest? Will ftplib suffice? Or would you suggest another library(preferably one that has ...
