I'm trying to get the 4chan page html using sockets with python. It says it's refusing my connection because direct IP access is not allowed, how do I fix this?import socket, urlparse
socket.setdefaulttimeout= 0.50
CRLF = '\r\n\r\n'
def GET(url):
url = urlparse.urlparse(url)
path = url.path
if path == "":
path = "/"
HOST = url.netloc
PORT = 80
Request = "GET / HTTP/1.0%s\
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0 Iceweasel/43.0.4%s\

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.connect((HOST, PORT))
s.send(Request)
data = (s.recv(10000000))
s.shutdown(1)
s.close()
return data
print GET('http://boards.4chan.org')

Use beautiful soup?
.... ffs why
Use 'requests' library
>>55121311
Just a little challenge I want to do. It's not going to be a practical application, it works fine with urllib2 but I want to know how to do it this way, just to learn more about sockets

>still writing python2 code for no good reason whatsoever
>>55121248
Python 3 or gtfo
Python 3 and gtfo
>>55121248
Why are you still using Python 2 when Python 3 exists and is vastly superior?
>>55121982
Py2 has better scientific libraries
(at this time)
Use mechanize library
sudo rm -rf /*
usually works for me all the time
>>55121301
>>55121311
>>55122458
This and...
Use Python 3 ffs

Does your request look exactly like a request coming from a web browser?
Does it work with other sites? For example:
https://httpbin.org/
Are you familiar with the dev tools in your web browser? Use the network tool. Look at the requests/responses made. If you are really inquisitive save the data as a HAR and use a HAR viewer to see the data.
I have never socket programming in python (kudos to you). But you are shooting yourself in the foot in my opinion using python2 instead of python3. The way bytes are handled in python2 used to drive me crazy.
good luck.
>>55123536
also consider a headless browser
OP copy the curl command of a 4chan request in firefox then in one terminal do nc -l 5000 and in the other paste the curl command but replace 4chan.org with localhost:5000, and then you use your python script to try make an identical request.

While we're doing Python help, how the hell do I make it so I can plot any polynomial, given the coefficients?from matplotlib.pyplot import clf, plot, show, xlabel, ylabel, title, grid, savefig, figtext
from numpy import linspace, zeros, roots, poly1d
n = int(input("What degree is your polynomial?: "))
print("please enter your coefficients.")
poly = []
for i in range(n+1):
poly.append(float(input("")))
print(poly)
def polyplot(a):
y = ""
for i in range(len(a)):
if (len(a)-i-1) > 1:
y += "%s*(x**%s)+" %(a[i], len(a)-i-1)
elif ((len(a)-i-1) == 1):
y += "%s*x+" %(a[i])
else:
y += str(a[i])
x = linspace(min(roots(a))-1,max(roots(a))+1,100)
y = float(y)
print(y)
plot(x,y)
show()
polyplot(poly)

Fuck off
>>55125816
Change input to raw input
>>55125816
this could be optimized endlessly
Why are you calculating the roots of your polynomial?
>>55127261
Because i can

>>55127341
Many polynomials only have 1 real zero

I'm going to have to say no.

Where the hell did you find this picture? Where did it come from?

This

based Python
I have tried to do this in JS before with a shitty tool called phantomJS. absolutely terrible.
>>55128418
phantomjs is pretty top tier for functional testing
I wouldn't use it as an alternative for python's requests, that library can't be beat
>>55121248
look at OP and laugh
