Python's Plugins for NetBeans 16
Dear Python Support, I'm looking for "Python Plugins for NetBeans 16". I already installed Python 3.11.2 for Windows 11 and I can't find such plugins to create python projects. I would appreciate it if you tell me where to download these plugins or if there is any other issue that I should do differently. Thank you very much in advance. Best to all.

SSL/TLS certificate verification suddenly broken, Python 3 on Windows 10
Hi All,
I ran into an error I, so far, cannot explain regarding Python's general
ability to communicate via SSL/TLS.
I'm using Python a lot to communicate with web servers and APIs, which
worked just fine until yesterday (or somewhen late last week).
I first noticed yesterday, when a requests-based call to a local web server
with a self-signed certificate failed. No worries, I thought, passing the
"verify=False" parameter to the request fixed the issue.
Later on I used the same call to a public web server with a valid,
CA-signed certificate and got the same error:
SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED]
certificate verify failed: unable to get local issuer certificate
(_ssl.c:1123)'))
That caused me to stop and try simple calls like
import requests
resp = requests.request('GET', 'https://www.nytimes.com/')
to fail alike. And I surely would not turn off certificate verification to
public websites.
First assuming a network connection problem I tried curl, openssl or a web
browser, all worked fine. Only Python fails.
I checked the installed certificate bundle, all correct and even upgraded
it to the latest version. No effect. I replaced it with the one curl is
using and that curl managed to verify the cert with. No effect.
By that time I was using a Python 3.7.9 installation on Windows 10 that ran
fine for months (and also before upgrading to 3.7.9).
I tried upgrading certifi and requests to the latest versions, which also
caused the same SSLError, so I downloaded the wheel packages and forced a
local upgrade - to no help.
After that I deleted the whole Python installation directory and replaced
it with a backup copy of a known-working version from a month ago. The
error kept appearing.
I then uninstalled Python completely, rebooted and installed Python 3.9.1,
downloaded from python.org.
The first to commands to issue were:
C:\Users\Carlos>python -V
Python 3.9.1
C:\Users\Carlos>pip list
PackageVersion
-- ---
pip20.2.3
setuptools 49.2.1
Could not fetch URL https://pypi.org/simple/pip/: There was a problem
confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org',
port=443): Max retries exceeded with url: /simple/pip/ (Caused by
SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED]
certificate verify failed: unable to get local issuer certificate
(_ssl.c:1123)'))) - skipping
So there went my theory of the requests module... It already happens with
the Python base installation (urllib3?). Obviously a freshly installed
Python with no modifications and no other modules installed fails to verify
each and every certificate.
I can rule out network errors as other machines using the same Internet
breakout work just fine with the same code. And it happens using a web
proxy and using no web proxy at all.
Aunty Google always tells me to set "verify=False" but that can't be the
solution for *this* problem. Unfortunately I have no idea where to look
next - not with a fresh installation failing.
Does anybody have a useful pointer for me? TIA!
Regards,
Carlos

subprocess check_output
Hi, Trying to run a specific command (ibstat) installed in /usr/sbin on an Ubuntu 15.04 machine, using subprocess.check_output and getting "/bin/sh: /usr/sbin/ibstat: No such file or directory" I tried the following: - running the command providing full path - running with executable=bash - running with (['/bin/bash', '-c' , "/usr/sbin/ibstat"]) Nothing worked ... Any idea? -carlos -- https://mail.python.org/mailman/listinfo/python-list

Thanks, I really don't know the difference between positional and keyboard
arguments so I think I must do some python reading. I'm not really a python
programmer (I'm a C, assembly, Java and C# programmer). Anyway the code is now
working.
Thanks a lot to both of you.

Error connecting to MySQL from Python
Hello guys I am currently working in a python project at my school. First I
want to make clear that I'm not a python programmer (I was just called to put
out the flames in this project because no one else would and I was brave enough
to say yes).
I have the following problem here. I have to write a method that connects to an
existing localhost MySQL database (I'm using connector version 1.0.12) and then
does pretty basic stuff. The parameters are sent by a GTK-written GUI (I didn't
write that interface). So I wrote my method like this:
--PYTHON CODE
def compMySQL(self, user, database, password, db_level, table_level,
column_level):
sql_page_textview = self.mainTree.get_widget('sql_text_view')
sql_page_textview.modify_font(pango.FontDescription("courier 10"))
sql_page_buffer = sql_page_textview.get_buffer()
#Gonna try connecting to DB
try:
print("Calling conn with U:{0} P:{1}
DB:{2}".format(user,password,database))
cnxOMC = mysql.connector.connect(user, password,'localhost',database)
except:
print "Error: Database connection failed. User name or Database name may
be wrong"
return
#More code ...
END OF PYTHON CODE-
But when I run my code I get this:
-CONSOLE OUTPUT
Calling conn with U:root P:PK17LP12r DB:TESTERS
Error: Database connection failed. User name or Database name may be wrong
---END OF COLSOLE OUTPUT---
And I don't know why, since the arguments sent are the same arguments that get
printed (telling me that the GUI the other guy coded works fine) and they are
valid login parameters. If I hardcode the login parameters directly insetad of
using the GUI everything goes ok and the functions executes properly; the
following code executes nice and smooth:
--PYTHON CODE-
def compMySQL(self, user, database, password, db_level, table_level,
column_level):
sql_page_textview = self.mainTree.get_widget('sql_text_view')
sql_page_textview.modify_font(pango.FontDescription("courier 10"))
sql_page_buffer = sql_page_textview.get_buffer()
#Gonna try hardcoding
try:
#print("Calling conn with U:{0} P:{1}
DB:{2}".format(user,password,database))
cnxOMC = mysql.connector.connect(user="root",
password='PK17LP12r',host='localhost',database='TESTERS')
print 'No prob with conn'
except:
print "Error: Database connection failed. User name or Database name may
be wrong"
return
#more code ...
END OF PYTHON CODE--
Console output:
CONSOLE OUTPUT--
No prob with conn
END OF CONSOLE OUTPUT---
Any ideas guys? This one is killing me. I'm just learning Python but I imagine
the problem to be something very easy for a seasoned python developer so any
help would be strongly appreciated.
Thanks in advance.

Off course there is! It might not suite your specific needs though. I'll just quote Knuth because it's pretty damn good: "A. An axiomatic approach. Although the associative law is not valid, the commutative law u (+) v == v (+) u (2) does hold, and this law can be a valuable conceptual asset in programming and in the analysis of programs. This example suggests that we should look for important laws that are satified by (+), (-), (*), and (/); it is not unreasonable to say that floating point routines should be designed to preserve as many of the ordinary mathematical laws as possible. If more axioms are valid, it becomes easier to write good programs, and programs also become more portable from machine to machine."

I'm not responsible for any damages it may cause to anyone!!! lol It just looks like those damn software disclaimers, doesn't it? ;) Depending on the jurisdiction things maybe very different. I've been told that in California it is really illegal to block IP addresses without a court order. Any Californians available to confirm that? "The sender of information over the Internet is the "owner" of both the information and the IP address attached to the information. The practice of IP address blocking "records" the IP address and "destroys" the information in the message "without the intent or permission of the owner of the information," and "usurp[s] the normal operation of the . . computer network." Software designed to record IP addresses and use them to block messages is thus a "computer contaminant" according to the above definition. " Source: http://im-from-missouri.blogspot.com.br/2007/05/ip-address-blocking-is-illegal-in.html Also check California Penal Code Section 502, "Unauthorized Access To Computers, Computer Systems and Computer Data": http://www.leginfo.ca.gov/cgi-bin/displaycode?section=pen&group=1-01000&file=484-502.9 The problem is serious and there are many cases, such as: http://www.theregister.co.uk/2011/10/13/dutch_isp_accuses_spamhaus/ >> Currently it may not only happen at the target of the DDoS attack, but be >> spread all over the internet where block lists are enforced. >> >> I don't expect that to happen and if it happens I'm surely in favor of >> protection against this type of 'solution' because it will block not only >> malicious clients but potentially many other legitimate clients. > > Banning a wide netblock is of course going to lock out legit clients. > But IP rotation means that can happen anyway.

I've tried to use dict() to create a dictionary to use like the switch
statement providing variable names instead of literals, such as:
>>> a='A'
>>> b='B'
>>> {a:0,b:1}#here the variables are resolved
{'A': 0, 'B': 1}
That's ok! But if I use dict() declaration:

RE: Beginner question
That doesn't even works because input() is the same as eval(raw_input()). So
you'll get a NameError exception.
I think you know that. Perhaps you mean raw_input() instead of input().
In that case the answer is yes, it can be more 'efficient' because the
if-then-else clause always breaks the while loop.
I think you are looking for is a switch statement, which Python don't have.
You can use the following structure to emulate a switch statement:
def function1():
if raw_input() in option1:
print('he tumbles over you')
else:
print('he stabs you')
def function2():
if raw_input() in option2:
print('you trip him up')
else:
print('he stabs you')
def default():
print 'DEFAULT'
switch = {
option1: function1,
option2: function2
}
switch.get(randomizer, default)()
Note that switch is a dictionary and you can use it without creating a
variable, for example:
{ option1: function1,
option2: function2
}.get(randomizer, default)()

Approximately equality CAN be commutative! I have just showed you that in the beginning using the following criteria: |v-u| <= ε*max(|u|,|v|) Which is implemented as fpc_aeq(): def fpc_aeq(u,v,eps=sys.float_info.epsilon): au=abs(u) av=abs(v) return abs(v-u) <= (eps*(au if au>av else av)) # |v-u| <= ε*max(|u|,|v|) > Approximate equality is not just non-commutative, it's also intransitive. > I'm reminded of a story about Ken Iverson, the creator of APL.

But it's a consequence of floating points (discretes representing a continuous set -- real numbers). Out of context, as you put it, looks like approximate equality is non-commutative, but that's wrong. Did you read the paper[1] you have suggested? Because SHARP APL in fact uses the same criteria I have mentioned and it supports it extensively to the point of applying it by default to many primitive functions, according to Lathwell[2] wich is reference 19 of [1]. "less than ab not equal a≠b floor ⌊a ceiling ⌈a membership a∊b index of a⍳b" I'll quote Lathwell. He called "tolerant comparison" what we are now calling "approximate equality". "Tolerant comparison considers two numbers to be equal if they are within some neighborhood. The neighborhood has a radius of ⎕ct times the larger of the two in absolute value." He says "larger of the two" which means "max(|u|,|v|)". So, you reference just reaffirms what TAOCP have demonstrated to be the best practice. I really don't know what the fuck you are arguing about? Can you show me at least one case where the commutative law wouldn't benefit the use of the approximate equality operator?

Since we are considering Chris's supposition ("to compare floating point

That's is totally irrelevant in this case. The commutative law is essential to

RE: Python #ifdef
Thank you! I made it run like the following. What do you think about that? IS there a better way? #The following runs on Python 2.7 sc3=''' # Python 3 def original(n): m = 0 for b in n.to_bytes(6, 'big'): m = 256*m + b return m ''' if sys.version_info[0] == 3: exec(sc3) -- http://mail.python.org/mailman/listinfo/python-list
Python #ifdef
Are there Python 'preprocessor directives'? I'd like to have something like '#ifdef' to mix code from Python 2 and 3 in a single file. Is that possible? How? -- http://mail.python.org/mailman/listinfo/python-list
