[Tutor] One question related to installation of Spyder
To those it may concern: Hi, I got a problem with installing Spyder. By the way, my desktop is of windows system. I know that before installing Spyder, I first have to equip my computer with PyQt4.x(x=4), QScintilla (x=1) and Python2.5 (and upper). Do you have any release of QScintilla in .exe form? I failed to find the detailed instruction about how to install with the source file.

thank you, this worked well.
here is the code:
###
import re
file=open('producers_google_map_code.txt', 'r')
data = repr( file.read().decode('utf-8') )
block = re.compile(ropenInfoWindowHtml\(.*?\\ticon: myIcon\\n)
b = block.findall(data)
block_list = []
for html in b:
namespace = {}
t = re.compile(rstrong(.*)\/strong)
title = t.findall(html)
for item in title:
namespace['title'] = item
u = re.compile(ra href=\\/(.*)\En savoir plus)
url = u.findall(html)
for item in url:
namespace['url'] = item
g = re.compile(rGLatLng\((\-?\d+\.\d*)\,\\n\s*(\-?\d+\.\d*)\))
lat = g.findall(html)
for item in lat:
namespace['LatLng'] = item
block_list.append(namespace)
###
can this be made better?

like
['d','a','v','i','d']
would b
['d','dd','a','aa','v','vv','i','ii','d','dd']
and then i wana replace all non 'd' characters with '.' a dot
i know how replace a specific character, but i don know how to replace
all characters other than a specific character

List indexed by position
['d','a','v','i','d']
0,1,2,3,4,5
Can index like this
a[1]
You can index and string too not need to be a list
a[1]
if you want find position of 'a' use this
a.find('a')

[Tutor] Algorithm for combined area of circles
Let there be 'n' circles (upper bound on n = 10**6) each of radius '1'. We enter their co-ordinates which are floating points and lies between (-1000, 1000). I need to find area of the resulting figure formed by intersection of circles.

[Tutor] tracking program
Hello I am fairly new to programming (which means I have never, ever, ever written a program). I have a book or two in Python, and so far I like it. I have a stupid question to ask; Is it possible to write an employee's internet tracking program in Python? I know I have a long way before I even attempt to code, but could someone describe what the process would entail? How would my python program be able to track an employee as he surfs the net (along with capture IP time wasted on the net). I know that there are programs that can be purchase to do what I 'm trying to accomplish. I just will like to write it my self.

Can anyone point me towards right direction? :( ~Shashwat Anand === This is probably spam, but... 1) My bad answer is to render them in pygame et al and do edge detection, if overlap color pixels a different color then count pixels. Probably would have to do in parts since the area is so big. Last I knew edge detection for circles sucks... 2) My trying to be good answer but is untested and probably doesn't work (ugh) is to use an FFT on the x and y axis. Numpy has an FFT. Since they all have the same circumference then maybe you can just scan to the left and right on the X axis and on the Y axis compute the difference and the resulting intersection. Put the intersection in a lookup chart under a key value for the differences (I think you can sum the x and y difference maybe not to have less keys). At some point you could probably just interpolate your lookup chart to save time unless you need it exact as possible. Is this some kind of vision algorithm?

You're right about having quite a while to go... but it's definitely possible. Basically, from about a 10,000' view, you would be writing a program to act as proxy between the web browser and the internet. I suppose at its most simple, you could write it with fairly few lines of code. The only thing I'm not sure on how to do is grab the outgoing connection. I presume it would require some type of loopback device, but I'm not terribly familiar with sockets/network programming. The IP part is pretty simple - a simple google search about python resolve ip address or something to that effect would probably get you good results. After learning a bit about program flow (i.e. writing a few programs), you could probably look up python socket programming and come up with some useful info.
