Depending on your DB-adapter, you are out of luck here. Either connect to a
db even if you don't need it, or try see if you can locate the
implementation in the module somehow.
ImportError: No module named MySQLdb
MySQLdb only available in Python2.

As of now, there is no mysql adaptor for Python3. Hence cant use escape_string()
I don't have the slightest clue what you want to say with that.

Maybe it would help if you explained what you are actually trying to
accomplish.
import csv
f = csv.reader(open('data.txt'), delimiter='\t') # 2GB text file
sql = INSERT INTO `data` VALUES (NULL,%s,%s,%s,%s,%s);
for row in f:
print (sql, (row[0],row[1],row[2],row[3],row[4]))
$ python3

In what simple way can I get just 0.04 ?

How do I achieve something like this using python ?
spaces = (form.has_key('spaces') ? form.getvalue('spaces') == 1 ? True
: False : False)
spaces = True if form.getvalue('spaces') == 1 if
form.has_key('spaces') else False else False

(1) what is produced on Anjanesh's machine
sys.getdefaultencoding()
'utf-8'
(2) it looks like a small snippet from a Python source file!
Its a file containing just JSON data - but has some unicode characters
as well as it has data from the web.
Anjanesh, Is it a .py file
Its a .json file. I
How do we know that from the what the OP posted?
Its CGI alright.
spaces = form.has_key('spaces') and form.getvalue('spaces') == '1'
But I just dont see how
spaces = (form.has_key('spaces') ? form.getvalue('spaces') == 1 ?
True: False : False)
is complicated in anyway. Its not that hard to read
Im reading a file. But there seems to be some encoding error.
f = open(filename)
data = f.read()
Traceback (most recent call last):
File pyshell#2, line 1, in module
data = f.read()
File C:\Python30\lib\io.py, line 1724, in read
decoder.decode(self.buffer.read(), final=True))
File
It does auto-detect it as cp1252- look at the files in the traceback and
you'll see lib\encodings\cp1252.py. Since cp1252 seems to be the wrong
encoding, try opening it as utf-8 or latin1 and see if that fixes it.
Thanks a lot ! utf-8 and latin1 were accepted !

Is there a way to return an iterable object ?
class twoTimes:
def __init__(self, n):
self.__n = n
def getNext():
self.__n *= 2
return self.__n
t = twoTimes(5)
while (n in t.getNext()): # while (n in t):
print (n)
--

You can also replace the whole class with a function thusly:
def two_times(n):
for k in itertools.count(1):
yield n * (2**k)
This function is then called a generator (because it generates an
iterator). You can now say
infinitely_doubling_numbers = two_times(2)
But how come a raise StopIteration in the next() method doesnt need to
be caught ? It works without breaking.
class twoTimes:
max = 10**10
def __init__(self, n):
self.__n = n
def next(self):
if self.__n self.max:
raise StopIteration
self.__n *= 2
Using Python 3.0
res = urllib.request.urlopen(url)
f = open('file.txt', 'wb') # Since res.read() returns bytes
f.write(res.read())
But newline and return feeds are stored as b14, 58a as text in the text file.
So how do I to convert res.read() to ascii on opening the file in
ascii mode f =
The problem seems be solved with urllib.request.urlretrieve()
I think the binary information read() was giving had headers like
content-size - but not HTTP headers.
The first couple of bytes indicate how much content to read and after
reading that content, the next set of bytes indicate the
Same requirement here.
But isnt there any mod_python for Python 3.0 ?
Or do we need to build it from source ourselves ?
I was hoping there would be mod_wsgi binaries for Python 3.0.

In PHP, if I do
str_replace(array('a', 'e', 'i', 'o', 'u'), '-', $str)
it'll replace all vowels with a hyphen in string $str.
Is there some equivalent in Python ?
Thanks

Thanks for the shutil.copyfileobj.
Oddly, the EOFError didnt work though.
