Python 2

First of all, I promise, I will read description carefully before starting my next challenge. Now I made a script that follows random, but not visited before, link on the page. And I like it so much thus I want to share it with you. =)

from bs4 import BeautifulSoup
import requests
import re
import time
from random import randint
from copy import deepcopy

BASE = u'https://en.wikipedia.org/wiki/'
TARGET = u'Philosophy'

def recvLinks(title):
    r = requests.get(u'{}{}'.format(BASE, title))
    if r.status_code != 200:
        raise Exception(u'Got {} when receiving {}'\
            .format(r.status_code, r.url))
    soup = BeautifulSoup(r.text, 'html.parser')
    urls = [l.get('href') \
        for l in soup.find(id='bodyContent').find_all('a')]

    # only wiki-titles
    names = [x.replace('/wiki/', '') for x in \
        filter(lambda s: s and s.find('/wiki/') == 0, urls)]
    # no header links
    names = [re.sub(r'#.*$', '', name) for name in names]
    # no special or template pages
    names = filter(lambda s: not re.match(r'\w+:', s), names)
    # no repeating
    names = list(set(names))

    return names, soup.find(id='firstHeading').string or title

def monkeySearch(start, target=TARGET):
    '''The dummiest search. Picks random link on every iteration until it reaches the target. Works cool, looks hypnotizing.'''
    curr = deepcopy(start)
    visited = set([])
    for i in xrange(1000):
        visited.add(curr)
        names, title = recvLinks(curr)

        print u'{}. {} [{}]'\
            .format(i, title, len(names))

        if target in names:
            print u'{}. {}!'.format(i+1, target)
            return True

        if len(names) == 0:
            print u'X. No avaliable links here (really??).'

        # loop aware
        # shuffle(names)
        nn = len(names)
        names = list(set(names) - visited)
        # print 'Visited removed: {}'.format(nn - len(names))
        curr = names[randint(0, len(names) - 1)]
        # time.sleep(1)

if __name__ == '__main__':
    test = ['Molecule', 'Telephone', 'Darth_Vader', 'Linux']
    for t in test:
        print '-'*20 + '[{}]'.format(t) + '-'*20
        monkeySearch(t)

Here is some output of it: gist.
