You need first to serialize the object to bytes that can go over the wire.
There is no predefined way to do that, so you can:
>>> import io
>>> file_like_object = io.BytesIO()
>>> PILImage.save(file_like_object, format='png')
and then in your POST request send file_like_object.getvalue() as the image
data. You will most probably need to add a Content-Type: image/png as a header.

Χρήστος Γεωργίου (Christos Georgiou) added the comment: First, let's make sure we're on the same page. - These files are created during the `$(MAKE) run_profile_task` stage. - They get removed during the `$(MAKE) clean` stage, along with the build directory. - The build directory gets recreated during the `$(MAKE) build_all_use_profile` stage, without any .gcda files this time. So you won't see these files after a successful build *if* you haven't taken measures to ensure they are saved during the build process. I save these files to a cpio file *before* `make clean` runs and restore them right afterwards. I suggest you modify `Makefile.pre.in` to include similar commands to the ones I mention in issue #23607 to verify whether your system creates these files or not. Now, for the info you required: It's a system running Ubuntu 14.04 64-bit with gcc 4.8.4. It's a build of Python with the `-mx32` flag, along with all required libraries for the needs of a specific project. (I think that the `-mx32` flag is not important to our discussion here though.)

Re: Shell like syntax for subprocess.Popen # overloading , , |

Thanks for your pointers. I think the input process output Syntax is more powerful , since it would let you build chaining commmands in a more readable fashion. The goal of this class would be to construct command chains such as: input processA | processB ouput Something which wouldn't be possible if only one operator is overloaded. I'm curious to see if its doable via overloading, since no __rgt__ methods exists... The problem with the operators chaining is that is treated differently than |. Check the following disassembly: import dis dis.dis(compile(abc, , eval)) 0 0 LOAD_NAME0 (a) 3 LOAD_NAME1 (b) 6 DUP_TOP 7 ROT_THREE 8 COMPARE_OP 0 () 11 JUMP_IF_FALSE 10 (to 24) 14 POP_TOP 15 LOAD_NAME2 (c) 18 COMPARE_OP 0 () 21 JUMP_FORWARD 2 (to 26) 24 ROT_TWO 25 POP_TOP 26 RETURN_VALUE dis.dis(compile(a|b|c, , eval)) 0 0 LOAD_NAME0 (a) 3 LOAD_NAME1 (b) 6 BINARY_OR 7 LOAD_NAME2 (c) 10 BINARY_OR 11 RETURN_VALUE The comparison operators include some logic in order to do what I mean (so that 4x10 works like 4x and x10, but x10 will never be evaluated if 4x is False), and that is why I suggested you use the | operator instead.

Close, but the pattern should allow arbitrary sequence of characters that
precede the alternating a's and b's to contain the letter 'a'. In other
words, the pattern should accept:
xayz123aaabbab
since the 'a' between the 'x' and 'y' is not directly followed by a 'b'.
Your proposed pattern rejects this string.
1.
(a{3})(?:b[ab]*)?$
This finds the first (leftmost) aaa either at the end of the string or
followed by 'b' and then arbitrary sequences of 'a' and 'b'.
This will also match (from second position on).
2.
If you insist in only three 'a's and you can add the constraint that:
* let s be the arbitrary sequence of characters at the start of your
searched text
* len(s) = 1 and not s.endswith('a')
then you'll have this reg.ex.
(?=[^a])(a{3})(?:b[ab]*)?$
3.
If you want to allow for a possible empty arbitrary sequence of characters
at the start and you don't mind search speed
^(?:.?*[^a])?(a{3})(?:b[ab]*)?$
This should cover you:

Re: Question about smtplib, and mail servers in general.

So I can send both my private mail and my work mail from both my home ISP's smtp server and my work's smtp server (but only if I am at the proper location). You might start having troubles, though, as soon as SPF checks get more widespread. Say your work mail is [EMAIL PROTECTED], and your private mail is [EMAIL PROTECTED]; if you send email through your office mail server with the envelope MAIL FROM: [EMAIL PROTECTED], then some (and eventually many) receiving servers shall ask yagoohoogle.com for their SPF record, and since your office mail server won't probably show up as a valid email sender from yagoohoogle.com , your email will get rejected.

There might be a python library for connecting to it, bypassing Access altogether. I think the OP wants to *use* .mdb files on a linux system without using any msjet*.dll libraries.

Re: Fighting Spam with Python
On Wed, 24 Aug 2005 22:46:28 -0700, rumours say that David MacQuigg dmq at pobox.com might have written: I'm writing some scripts to check incoming mail against a registry of reputable senders, using the new authentication methods. Python is ideal for this because it will give mail-system admins the ability to experiment with the different methods, and provide some real-world feedback sorely needed by the advocates of each method. So far, we have SPF and CSV. See http://purl.net/macquigg/email/python for the latest project status. I am on the side of advocating SPF records --and I am one of the first four postmasters in my country's TLD that set up SPF records for two of the email domains I'm administrating. SPF is an internet draft now.[1] Your method is/will_not be free (as in beer), as hinted in http://www.ece.arizona.edu/~edatools/home/email/registry/Form-Sender01.htm . *That* is a drawback similar to the licensing of the Microsoft's Sender/Caller-ID scheme. Why not support open, free standards? I have developped scripts of my own to perform various consistency checks (including SPF lookup) and maintain my own black list (I am consulting three RBL's which I have found to be close to my standards, but I want to avoid excessive usage of their bandwidth), and although it takes some time almost every day overseeing things, I would be very timid to support such a free (as in jazz :) scheme. I mean, the reputation idea is nice, but paying for this reputation won't help its spreading. Good luck with it as a business, though.
