permutations

2009. 5. 26. 00:07 in Library/Python

from __future__ import generators

def xcombinations(items, n):
    if n==0: yield []
    else:
        for i in range(len(items)):
            for cc in xcombinations(items[:i]+items[i+1:],n-1):
                yield [items[i]]+cc

def xpermutations(items):
    return xcombinations(items, len(items))

if __name__=='__main__':
    '''
    for p in xpermutations(['0','1','2','3']):
        print (''.join(p))
    '''

    arr = xpermutations(['0','1','2','3'])

    print('indices[24][4]={')
    for item in arr:
        form = '{%s,%s,%s,%s},' % (item[0], item[1], item[2], item[3])
        print(form)
    print('}')

compatible with python 3.x+

Look-up secondary domain by using alphabet permutation.

2008. 10. 21. 18:48 in Library/Python

from socket import gethostbyname

alp = map(chr, range(97,123)) # a-z
suffix = '.xxxx.net'
prefix = [a+b+c for a in alp for b in alp for c in alp]

f = file('result.txt', 'w+')
cnt = 0
for p in prefix:
    hostname = p + suffix
    cnt += 1
    if cnt % 100 == 0:
        print cnt, hostname
    try:
        ip = gethostbyname(hostname)
        f.write(hostname + ' : ' + ip + '\n')
        print hostname
    except:
        continue

f.close()

어렴풋이 본 서브도메인.. 주소가 생각나지 않을 때 사용했다.

Generate .exe by using ironpython

2008. 10. 8. 09:13 in Library/Python

ironpython 으로 .exe를 생성할 수 있다. ironpython이 윈도우용만 존재하는 것이 아니라 리눅스에서도 이것이 가능한데(리눅스에서는 .net 환경으로 mono라는 것이 존재한다), 리눅스에서 만든 .exe를 윈도우즈에서 실행하니 잘 안되더라. 아무튼.. .exe만드는 방법.

# compiler.py
from IronPython.Hosting import PythonCompiler

from System.Collections.Generic import List
sources = List[str]()
sources.Add('hello.py')
outfile = 'hello.exe'

compiler = PythonCompiler(sources, outfile)
compiler.Compile()

IronPython 참조 에러시 다음 추가:
import clr
clr.AddReferenceByPartialName("IronPython")

python test suite example

2008. 10. 6. 10:36 in Library/Python

import unittest

class TestUtility(unittest.TestCase):
    def testExtractFileNm(self):
        self.assertEquals(1, 1)


def suite():
    suite = unittest.TestSuite()
    suite.addTest(unittest.makeSuite(TestUtility))
    return suite

if __name__=='__main__':
    unittest.TextTestRunner(verbosity=2).run(suite())

handling cookies with httplib2 and urlib2

 #!/usr/bin/env python

http = httplib2.Http()

url = 'http://www.example.com/login'
