I have a written a Python module which due to its specifics needs to have a MySQL database connection. Right now, details of this connection (host, database, username and password to connect with) are stored in /etc/mymodule.conf in plaintext, which is obviously not a good idea. Supposedly, the /etc/mymodule.conf file is edited by the r...

Hi all, I'm looking for a good library that will integrate stiff ODEs in Python. The issue is, scipy's odeint gives me good solutions sometimes, but the slightest change in the initial conditions causes it to fall down and give up. The same problem is solved quite happily by MATLAB's stiff solvers (ode15s and ode23s), but I can't use it...
From Whats the java equivalent of Python’s urllib.urlencode? Like >>> urllib.urlencode({'abc':'d f', 'def': '-!2'}) 'abc=d+f&def=-%212' Where I can pass a HashMap of key values and it encodes and gives me the url string .. Edit: I wanted to avoid this scenario String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.en...

But I can't find any example code anywhere, except for specific code focusing on sorting date fields. How would one go about sorting a relatively large CSV file (tens of thousand lines) on multiple fields, in order? Py...
