When Python meets Vim
<ul>
<li>
.vimrc for Python: <a href="http://www.vex.net/~x/python_and_vim.html">http://www.vex.net/~x/python_and_vim.html</a>
<li> exec python script in vim: noremap <F7> :!python %<CR>
</ul>

Python basics:
<ul>
<li>
__dict__: instance variables in a dictionary that belongs to the object. it contains all other attributes of the object.
Each python object has a __dict__ atttribute which is a dictionary containing all other attributes. e.g. when you type self.attr python is actually doing self.__dict__['attr']. As you can imagine using a dictionary to store attribute takes some extra space & time for accessing it.

However, when you use __slots__, any object created for that class won't have a __dict__ attribute. Instead, all attribute access is done directly via pointers.
<li>
dir():"attributes, its class's attributes, and recursively the attributes of its class's base classes."
<li>
Special methods such as __contains__ are only special when defined on the class, not on the instance (except in legacy classes in Python 2, which you should not use anyway).

<li>
static methods vs. class methods: static methods are a func defined in a class body. class methods change with subclasses.
<li>
decorators: syntax sugar. semantically equivalent to expanding it. http://www.artima.com/weblogs/viewpost.jsp?thread=240808

Python Encoding/Decoding:
<ul>
<li>
Decoding: interpret the string to unicode
str.decode('utf8')
from utf8 to unicode
check http://farmdev.com/talks/unicode/
http://gomputor.wordpress.com/2008/09/22/convert-a-file-in-utf-8-or-any-encoding-with-python/
<li>
Encoding(charset): encode string to charset chars
str.encode('utf8')
from unicode to utf8
<pre>
  1 import sys
  2 
  3 s = 'abc123'
  4 print type(s)
  5 
  6 u = u'abc123'
  7 print type(u)
  8 
  9 print type(s.decode('ascii'))
 10 print type(s.encode('utf8'))
 11 
 12 print type(u.decode('ascii'))
 13 print type(u.encode('utf8'))

output:
< type 'str'>
< type 'unicode'>
< type 'unicode'>
< type 'str'>
< type 'unicode'>
