This works as easy,when you search for a data in google.com via chrome

import webbrowser
search_word = 'Rose'
url = 'https://www.google.com/#q={}'.format(search_word)
chrome_path = 'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe %s'
webbrowser.get(chrome_path)
webbrowser.open(url)

I would use a form of binary search approach -- unless there is
an obvious cause, such as GIL not hold.

For the "binary search approach", you would need a non destructive way
to detect the corruption during a "gdb" debugging session.
There is a set of "gdb" macros to manage (e.g. print out) Python
objects from the debugger. Based on them, you might develop similar
macros to access dicts and check for their validity.
Once you have a way to detect the corruption, you can step into
the "PyDateTime_IMPORT" and find out where the corruption happens.

valgrind is what I was going to suggest. You have to compile Python with 
extra flags to get it to integrate well with valgrind though, because of 
its custom allocators (if you're just trying to run it now and are 
confused by the results, that might be why).


valgrind (or rather, valgrind's "memcheck" module) has command line 
flags for giving deeper information than the default, but at the expense 
of tracking more and slowing things down.

How to configure SSL client trusted CA certificates?

[gangyang7]

Hi,



I'm using Python 3.X (3.5 on Windows 2008 and 3.4 on CentOS 6.7) and 
encountered an SSL client side CA certificates issue. The issue came up when a 
third-party package (django-cas-ng) tried to verify the CAS service ticket (ST) 
by calling CAS server using requests.get(...) and failed with 
CERTIFICATE_VERIFY_FAILED error. The CAS server is accessed by HTTPS with a 
self-signed server certificate. Following some suggestions on the internet, 
I've tried to modify django-cas-ng's code to call requests.get(..) with verify 
parameter, such as requests.get(..., verify=False) and requests.get(..., 
verify="CAS server cert"). Both workarounds worked, but I can't change 
third-party package code. I also tried to add the CAS server cert to the 
underlying OS (Windows 2008 and CentOS 6.7), but it did not help.



My question is where does SSL client code get the trusted CA certificates from, 
from Python or the underlying OS? What configuration do I need in order for the 
SSL client to conduct the SSL handshake successfully?



Appreciate any help!

Looking at it (compared to the original), It has Usenet headers for
comp.lang.python (and a path header indicating an origin at
eternal-september.org), and headers associated with FidoNet and

True, which is why as much as possible should be done with raw video
data that never changes, and then text files that indicate the
alterations. The raw video data gets recorded once and then kept
as-is, and then your editing work gets saved into some textual form
(maybe a JSON file, maybe a series of commands) that you can plausibly
diff. The only time you actually add binary files is when you do
initial recording work, and a diff that affects those files should
always be suspicious.

(Obviously it would be horrendously inefficient to work from the raw
files all the time. But the edited files could be gitignored, since
they can be reconstructed from the originals; share them for
convenience, but don't sweat their loss.)

I am afraid he means that it create mishmash in word document...

Dear accessnewbie I propose divide problem to smaller subproblems.

For example make python code as simple as possible (avoid python part
if you could! As Deborah wrote it is very probably not problem in
python)

And try to explicitly try to write example text where is bold part.
#myBlurb = "My Favorite Cars -
 My favorite cars are available at "
 + myText + ""
myBlurb = "My Favorite Cars -
 My favorite cars are available at 
my garage "

if it is still wrong try to make more and more similar text to:
myBlurb = "My Favorite Cars - My favorite cars are available at
my garage"

I mean for example remove "" part etc.

Second - This is probably not your problem (unless you have special
char in your example myList) but if you could have xml spec chars in
your input then python could help. See example ->

>>> from xml.sax.saxutils import escape
>>> escape("< & >")
'< & >'

myBlurb = "My Favorite Cars - My favorite cars are available at
" + escape(myText) + ""  # this is safer than your code!

I hope you understand why it is useful. :)

When I setup TLS for a K/V pair database with self-signed certs, I could supply 
two types of certs

-peer certs with the IP and DNS name tied to the node signed by the self-signed 
CA I generated
-client cert that had the IP and DNS for ALL the machines in the cluster signed 
by the CA

To connect to the any of the clients, I had to provide the client cert, key, 
and the CA.  That's just the way the software built.

For browsers, each browser has a CA from various authorities and you add an 
intermediate key signed by one of those authorities (e.g. Verisign which costs 
$2000) to the browser to allow you to access a specific domain through a 
wildcard cert.  My K/V software didn't support that.

Look at how CentOS 6 stores it's certs in /etc/pki.  I think where you'd put 
your CA + client key bundle.  Which means you have to do this for all machines 
that run your code.  That's not optimal or at all portable.  You'll probably 
have to deliver the app as a VM or a docker container to put it all together.

Good luck.
