ANN: obfuscate 0.2.2
by Steven D'Aprano Nov. 14, 2017

Nov. 14, 2017

I am pleased to announce the first stable release of obfuscate, version 0.2.2. http://pypi.python.org/pypi/obfuscate/ obfuscate is a pure-Python module providing classical encryption algorithms suitable for obfuscating and unobfuscating text. This is a maintenance release of back-end and API changes but no new ciphers. This should be considered the first stable API for obfuscate. obfuscate includes the following ciphers: - rot13, rot5, rot18, rot47 - atbash - Caesar cipher - Keyword - Affine - Playfair, Playfair6, Playfair16 - frob (xor) - Vigenere - RailFence - plus others. DISCLAIMER: obfuscate is not cryptographically strong, and should not be used where high security is required. obfuscate is released under the MIT licence. Requires Python 2.5 or 2.6. -- Steven

The typical use case (disappearing placeholder) should also trigger, when somebody uses the tab key to set the focus to the window. This can be achieved by binding to the <FocusIn> event instead: search.bind("<FocusIn>", clear_search) In addition, repeated clicking does not clear the text then. Christian

Yes, I have a Tex engine on my system. How can i fix the problem with the PATH ? Even if i execute the .py script directly by python (I mean :not inside a LateX file) pyx need to reach the TeX system ? Is there a config file to fix the PATH ? Where ? Thanks a lot !!

What use of string module?
by fl Sept. 18, 2017

Sept. 18, 2017

Hi, I read the online help about string. It lists string constants, string formatting, template strings and string functions. After reading these, I am still puzzled about how to use the string module. Could you show me a few example about this module? Thanks

Best way to insert sorted in a list
by SherjilOzair Sept. 8, 2017

Sept. 8, 2017

There are basically two ways to go about this. One is, to append the new value, and then sort the list. Another is to traverse the list, and insert the new value at the appropriate position. The second one's complexity is O(N), while the first one's is O(N * log N). Still, the second one works much better, because C code is being used instead of pythons. Still, being a programmer, using the first way (a.insert(x); a.sort()), does not feel right. What has the community to say about this ? What is the best (fastest) way to insert sorted in a list ?

Changing filenames from Greeklish => Greek (subprocess complain)

But i wish to presnt filename sin Greek and not in Greeklish http://superhost.gr/?page=files.py as it is now. What can i do to make pth script accept greek filenames too? Why does subprocess is complaining?

Hello, do you know of any way to copy locked / opened files under win xp? I know there is something like "Volume Shadow Copy" but I don't know how to use it. Maybe someone already has a python solution? Many thanks Daniel

Feature suggestion -- return if true
by zildjohn01 Aug. 25, 2017

Aug. 25, 2017

This is an idea I've had bouncing around in my head for a long time now. I propose the following syntax: return? expr be expanded to _temp = expr if _temp: return _temp It's a pattern I use all the time in my code, and although it's a bit unorthodox, IMO it's concise, readable, and easily understandable. Thoughts?
