I’d like to have a python program alert me when it has completed its task by making a beep noise. Currently, I use import os and then use a command line speech program to say “Process complete”. I much rather it be a simple “bell.”
I have a DataFrame, say a volatility surface with index as time and column as strike. How do I do two dimensional interpolation? I can reindex but how do i deal with NaN? I know we can fillna(method='pad') but it is not even linear interpolation. Is there a way we can plug in our own method to do interpolation?
I’ve got an object with a short string attribute, and a long multi-line string attribute. I want to write the short string as a YAML quoted scalar, and the multi-line string as a literal scalar:
I have a textfile, let’s call it goodlines.txt and I want to load it and make a list that contains each line in the text file.
How do you store a “blob” of binary data using Django’s ORM, with a PostgreSQL backend? Yes, I know Django frowns upon that sort of thing, and yes, I know they prefer you use the ImageField or FileField for that, but suffice it to say, that’s impractical for my application.

i’m starting the TDD development attitude and am writting unit-tests for my django application. I’m aware of fixtures and know that’s the way tests should be executed, but for a given test i do need to execute it on the whole database, and json fixture for 10+ million row database is not something i’d like to handle, moreover, this test is “read-only”.
I am trying to loop through a list of objects deleting an element from each object. Each object is a new line. I am trying to then save the new file as is without the element contained within the objects.
