Use print( string ) for python 3k. name = ‘moose’ adjective = ‘squishy’ print ‘{name} is {adjective}’.format(**locals()) # moose is squishy # vars() with no args is same as locals() print ‘{name} is {adjective}’.format(**vars()) # moose is squishy Using vars to access object … Continue reading

explicit is not better than implicit
I’m sick of all the python fangeeks always using the argument that “explicit is better than implicit” to justify python behaviors. I think it’s a good design principle to consider, but it is not a overarching commandment that good code should always be explicit. Convenience and readability is sometimes better than explicit. Use your brain, don’t be a eibti zombie.

Python woes
It’s cool that there are so many Python modules available, but it’s kinda a pain to install them all. It’s too bad easy_install doesn’t do better dependency checking. It just errors out when there’s something missing. I couldn’t get numpy to work with the 64 bit version of Python 2.7 for Windows, so I uninstalled the 64 bit version and … Continue reading

Vim: Save and Run Shortcut
Make Vim more IDE-like by assigning F5 to save and run your current script. Just add this to your ~/.vimrc map <F5> <Esc>:w<CR>:!%:p<CR> This maps the F5 key to run two things: :w, which saves your file, and :!%:p, which will run your current script (! runs a shell command and %:p expands to the path of your current file). … Continue reading
