Brainfuck in One Line of Python
A question that has bugged me for a while is whether or not it is possible to simulate a Turing Machine in one semicolon-free expression of Python. If you allow for liberal use of eval then the answer is (trivially) positive, but it's not directly obvious that it would be true without such workarounds. Python's lack of tail-call elimination makes its lambda calculus bounded in scope, as the user i
Naive Bayes classifier in 50 lines - UMBC ebiquity
The Naive Bayes classifier is one of the most versatile machine learning algorithms that I have seen around during my meager experience as a graduate student, and I wanted to do a toy implementation for fun. At its core, the implementation is reduced to a form of counting, and the entire Python module, including a test harness took only 50 lines of code. I haven’t really evaluated the performance,
How to read Haskell like Python : ezyang's blog
November 14, 2011tl;dr — Save this page for future reference. Have you ever been in the situation where you need to quickly understand what a piece of code in some unfamiliar language does? If the language looks a lot like what you’re comfortable with, you can usually guess what large amounts of the code does; even if you may not be completely familiar how all the language features work. For Haske
Moka - Minimalist functional python library
Download Moka Minimalist functional python library Moka is a minimalist functional library wrapping commons Python default data structures. In other words, it let you chain functional constructs in a readable and pythonic way. (List() # Create a new instance of moka.List .extend(range(1,20)) # Insert the numbers from 1 to 20 .keep(lambda x: x > 5) # Keep only the numbers bigger than 5 .rem(lambda
What Code Golf Taught Me About Python by Louis Brandy
So I’ve become seriously addicted to code golf. For those that don’t know, code golf is a competition where you try to pass some programming test with a program consisting of the least number of characters. I chose to play code golf in Python because I wanted to learn more about the language. I’ll probably eventually do the same for Ruby. I know the title of this might be controversial. There’s al
CAS - CalNet Authentication Service Login
How to Sign In as a SPA To sign in to a Special Purpose Account (SPA) via a list, add a "+" to your CalNet ID (e.g., "+mycalnetid"), then enter your passphrase. The next screen will show a drop-down list of all the SPAs you have permission to access. Select the SPA you wish to sign in as. To sign in directly as a SPA, enter the SPA name, "+", and your CalNet ID into the CalNet ID field (e.g., “spa
(An ((Even Better) Lisp) Interpreter (in Python))
In a previous essay I showed how to write a simple Lisp interpreter in 90 lines of Python: lis.py. In this essay I make the implementation, lispy.py, three times more complicated, but more complete. Each section handles an addition. (1) New data types: string, boolean, complex, port Adding a new data type to Lispy has three parts: the internal representation of the data, the procedures that operat
Requests: HTTP for Humans — Requests 2.4.3 documentation
Requests: HTTP for Humans™¶ Release v2.32.5. (Installation) Requests is an elegant and simple HTTP library for Python, built for human beings. Behold, the power of Requests: >>> r = requests.get('https://api.github.com/user', auth=('user', 'pass')) >>> r.status_code 200 >>> r.headers['content-type'] 'application/json; charset=utf8' >>> r.encoding 'utf-8' >>> r.text '{"type":"User"...' >>> r.json()
What does Ruby have that Python doesn't, and vice versa? - Stack Overflow
There is a lot of discussions of Python vs Ruby, and I all find them completely unhelpful, because they all turn around why feature X sucks in language Y, or that claim language Y doesn't have X, although in fact it does. I also know exactly why I prefer Python, but that's also subjective, and wouldn't help anybody choosing, as they might not have the same tastes in development as I do. It would t
