I am new to python and don't know the best way to do this. I have a list of tuples which represent points and another list which represents offsets. I need a set of all the combinations that this forms. Here's some code: offsets = [( 0, 0),( 0,-1),( 0, 1),( 1, 0),(-1, 0)] points = [( 1, 5),( 3, 3),( 8, 7)] So my set of combined point...

My first approach was this (javascript style) >>> status = object() >>> status.foo = 3 Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'object' object has no attribute 'foo' Definitely not what I expected, because th...
Note: i edited my Q (in the title) so that it better reflects what i actually want to know. In the original title and in the text of my Q, i referred to the source of the thrown exception; what i meant, and what i should have referred to, as pointed out in one of the high-strung but otherwise helpful response below, is the module that t...
Hi, I'll be taking a Python-based computer science class next semester using my MacBook Pro. It will be centered around a custom-designed package for this class. The problem is that this package is being sponsored by Microsoft Research, so it was obviously designed with Windows in mind. Supposedly, it runs on Mac OS and Linux too, but t...
Example dump from the list of a directory: hello:3.1 GB world:1.2 MB foo:956.2 KB The above list is in the format of FILE:VALUE UNIT.

I thought perhaps to parse each line for the unit via the pattern ":VALUE UNIT" (or somehow use the delimiter) then run it throug...

I'm trying to figure out whether Python can be a suitable Java alternative for enterprise / web applications. Which are the ideal cases where you would prefer to use Python instead of Java? How would a typical Python web application (dat...

I wish to retrieve the source of a website, that is dynamically generated upon clicking a link. The link itself is as below: <a onclick="function(); return false" href="#">Link</a> This stops me from directly querying for a URL that would allow me to get the dynamically generated website (urllib/2).
