how to write configure

[contro opinion]

PyGObject uses the standard autotools for the build infrastructure.  To
build, it should be as simple as running:

$ ./configure --prefix=

my python2.7 is  in  /usr/lib/python2.7

will  i  write :
./configure --prefix=/usr/lib/python2.7

or

./configure --prefix=/usr/lib

w.connect('destroy', destroy_cb)

l = Gtk.Label()
l.set_text("Hello World!")
w.add(l)

w.show_all()

lxml can't output right unicode result

i eidt a file and save it in gbk encode named test. my system is

in terminal i input:

xxd  test

000: 3c68 746d 6c3e 0a3c 703e c4e3 3c2f 703e  ...
010: 0a3c 2f68 746d 6c3e 0a   ..

你 is you in english,
"\xc4\xe3" is the gbk encode of it.
"\xe4\xbd\xe3" is the utf-8 encode of it.
"u\x4f\x60" is the unicode encode of it.
now i parse it in lxml

>>> "你"
'\xe4\xbd\xa0'
>>> "你".decode("utf-8")
u'\u4f60'
>>> "你".decode("utf-8").encode("gbk")
'\xc4\xe3'
>>>

code1:

>>> import lxml.html
>>> root=lxml.html.parse("test")
>>> d=root.xpath("//p")
>>> d[0].text_content()
u'\xc4\xe3'

in material ,lxml parse file to output the unicode form.
why the d[0].text_content() can not output u'\x4f\x60'?

code2:

import codecs
import lxml.html
f = codecs.open('test', 'r', 'gbk')
root=lxml.html.parse(f)
d=root.xpath("//p")
d[0].text_content()
u'\xe4\xbd\xa0'

why the d[0].text_content() can not output u'\x4f\x60'?

as far as i know

OSError: [WinError 10022] An invalid argument was supplied in udp python file

When i test an udp.py file on server and client in python34.

PORT = 1060

while True:
  data, address = s.recvfrom(MAX)
  print('The client at', address, 'says', repr(data))
  s.sendto('Your data was %d bytes' % len(data), address)
elif sys.argv[1:] == ['client']:
print('Address before sending:',s.getsockname())
s.sendto('This is my message',('127.0.0.1', PORT))
print('Address after sending',s.getsockname())
data, address = s.recvfrom(MAX)
print('The server', address, 'says', repr(data))

function problem

[contro opinion]

code1:

def FirstDeco(func):
   print 'haha'
   y=func()
   return y
   print  y


@FirstDeco
def test():
  print 'asdf'
  return  7

result :
haha
asdf

code2:

def FirstDeco(func):
   print 'haha'
   y=func()
   #return y
   print  y


@FirstDeco
def test():
  print 'asdf'
  return  7

result :
haha
asdf
7

why the result of code1 and code2  is different?

in the middle of web ,there is a problem,how to parse

[contro opinion]

here is my code:

import urllib

file=urllib.urlopen(down).read()
root=lxml.html.document_fromstring(file)

data1 = root.xpath('//tr[@class="tr_normal"  and  .//img]')
print "the row which contains img  :"
for u in data1:
print  u.text_content()

data2 = root.xpath('//tr[@class="tr_normal"  and  not(.//img)]')
print "the row which do not contain img  :"
for u in data2:
print  u.text_content()


the output is :(i omit many lines )

the row which contains img  :

the row which do not contain img  :
1长江实业1,000#HOF
many lines omitted
00327百富环球1,000#H
