On further inspection, it seems that strptime() in 2.7 doesn't handle %z

As far as I can tell from running the following, it all seems to work as expected in python 3.2 (and hence I expect in 3.4).

Please learn to use usenet properly. Comments go below the text they refer to. What version of python are you using? I know what version of the documentation you are looking at, but as I explained inj an earlier post, the implementation varies between different python versions, and for example python 2.7 strptime seems to completely ignore the %z in the format string, so again, what version of python are you using? To check your python version: $ python >>> import sys >>> sys.version will output something like: '2.7.3 (default, Feb 27 2014, 19:58:35) \n[GCC 4.6.3]' for Python 2.7 or: '3.2.3 (default, Feb 27 2014, 21:31:18) \n[GCC 4.6.3]' for Python 3.2. Again, I stress, we need to know what version of python you are using to help you! Did you run the code I posted? Did you get the same output as me? If you didn't, what was different. If you did get the same output, what do you think is wrong with it? -- Denis McMahon, denismfmcma...@gmail.com -- https://mail.python.org/mailman/listinfo/python-list

I don't care, frankly. I'm still not going to help anyone to break CAPTCHAs automatically. If you're unable to solve CAPTCHAs, it's equivalent to being unable to run VBScript or unable to download music over a proprietary streaming protocol: it's a problem to be solved by getting the server admin to change policy, *not* by trying to script around it. Scripting around the problem just forces everyone to make it harder to script around the problem. You're joining the arms race, and on the wrong side. Breaking CAPTCHAs is *not* good for any issue.

Ah, interesting. I was looking at the time.strptime docs. I incorrectly assumed that since help(datetime.strptime) defers to help(time.strptime), the docs would also.

Unicode in cgi-script with apache2
Hi,
I've got a little script:
#!/usr/bin/env python3
print("Content-Type: text/html")
print("Cache-Control: no-cache, must-revalidate")# HTTP/1.1
print("Expires: Sat, 26 Jul 1997 05:00:00 GMT") # Date in the past
print("")
f = open("/var/www/cgi-data/index.html", "r")
for line in f:
print(line,end='')
If I run the script in the terminal, it nicely prints the webpage
'index.html'.
If access the script through a webbrowser, apache gives an error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position
1791: ordinal not in range(128)
I've done a hole afternoon of reading on fora and blogs, I don't have a
solution.
Can anyone help me?

1) this is not the way to get python to generate a web page, if you dont
want to use an existing framework (for example if you are doing this ans
an educational exercise) i suggest to google SWGI
2) you need to encode your output strings into a format apache/html
protocols can support - UTF8 is probably best here.
change your pint function to
print(line.encode('utf'),end='')
3) Ignore any subsequent advice from JMF even when he is trying to help
he is invariable wrong.

>>> datetime.strptime("Mon, 9\t\t\tAug\n2014\r7:36:46\f-0700", "%a, %d %b %Y

datetime.datetime(2014, 8, 9, 7, 36, 46,

strptime doesn't seem to care about variations in whitespace as long
as some is present, or missing leading zeroes (although it does throw
an error if the time zone offset is only 3 digits).

Logging multiple formats to the same file
So I've got my program log going to a RotatingFileHandler (actually a
subclass that ensmartens the umask, but I digress). I'd like to be
able to provide information to the logger that is formatted two
different ways, primarily just so that I can provide a Program Started
message into the log.
What I've got going right now works, but boy it feels like I had to
butcher the intent of the logging module to pull it off. Does anyone
have any better ideas than...
class BannerFormatter(logging.Formatter):
"""
Uses the assigned formatting, unless the name of the logger is
'BANNER', in which case we use the special alternate banner
format. """

self.normal = logging.Formatter(*args, **kwargs)
self.banner = logging.Formatter(
'\n\n%(asctime)s - ** %(message)s **'
)
def format(self, record):
if record.name == 'BANNER':
return self.banner.format(record)
else:
return self.normal.format(record)

Now at least you get to look at what URLReader() returned. Did it
return what you expected? If not, then there might be something wrong
in your URLReader() function. If it is what you expected, then I would
start looking at the pattern to see if it's correct. Either way, you've

If you didn't change the code, how could the *exact same code* not mask the question mark last week, but this week suddenly start masking it, despite not changing? There are three things that can cause a change in behaviour: - the re module has changed; - the pattern has changed; - the text you are searching has changed. Have you removed the re module and replaced it with a different one? Did you update Python to a new version? Have you changed the regex search pattern? Has the text you are searching changed?
