A Complete Tutorial on Ridge and Lasso Regression in Python http://www.analyticsvidhya.com/blog/2016/01/complete-tutorial-ridge-lasso-r… In Step 2 "Why Penalize the Magnitude of Coefficients?" we are shown this code: #Importing libraries. The same will be used throughout the article. import numpy as np import pandas as pd import random import matplotlib.pyplot as plt %matplotlib inline I get an error on the last line. I am running this code in Idle Python 3.4.4 Shell...

[RELEASE] Python 3.11.1, 3.10.9, 3.9.16, 3.8.16, 3.7.16, and 3.12.0 alpha 3 are now available
by Łukasz Langa Feb. 18, 2023

Feb. 18, 2023

Greetings! We bring you a slew of releases this fine Saint Nicholas / Sinterklaas day. Six simultaneous releases has got to be some record. There’s one more record we broke this time, you’ll see below. In any case, updating is recommended due to security content: 3.7 - 3.12: gh-98739 <https://github.com/python/cpython/issues/98739>: Updated bundled libexpat to 2.5.0 to fix CVE-2022-43680 <https://nvd.nist.gov/vuln/detail/CVE-2022-43680> (heap use-after-free). 3.7 - 3.12: gh-98433 <https://github.com/python/cpython/issues/98433>: The IDNA codec decoder used on DNS hostnames by socket or asyncio related name resolution functions no longer involves a quadratic algorithm to fix CVE-2022-45061 <https://nvd.nist.gov/vuln/detail/CVE-2022-45061>. This prevents a potential CPU denial of service if an out-of-spec excessive length hostname involving bidirectional characters were decoded. Some protocols such as urllib http 3xx redirects potentially allow for an attacker to supply such a name. 3.7 - 3.12: gh-100001 <https://github.com/python/cpython/issues/100001>: python -m http.server no longer allows terminal control characters sent within a garbage request to be printed to the stderr server log. 3.8 - 3.12: gh-87604 <https://github.com/python/cpython/issues/87604>: Avoid publishing list of active per-interpreter audit hooks via the gc module. 3.9 - 3.10 (already released in 3.11+ before): gh-97514 <https://github.com/python/cpython/issues/97514>: On Linux the multiprocessing module returns to using filesystem backed unix domain sockets for communication with the forkserver process instead of the Linux abstract socket namespace. Only code that chooses to use the “forkserver” start method is affected. This prevents Linux CVE-2022-42919 <https://nvd.nist.gov/vuln/detail/CVE-2022-42919> (potential privilege escalation) as abstract sockets have no permissions and could allow any user on the system in the same network namespace (often the whole system) to inject code into the multiprocessing forkserver process. This was a potential privilege escalation. Filesystem based socket permissions restrict this to the forkserver process user as was the default in Python 3.8 and earlier. 3.7 - 3.10: gh-98517 <https://github.com/python/cpython/issues/98517>: Port XKCP’s fix for the buffer overflows in SHA-3 to fix CVE-2022-37454 <https://nvd.nist.gov/vuln/detail/CVE-2022-37454>. 3.7 - 3.9 (already released in 3.10+ before): gh-68966 <https://github.com/python/cpython/issues/68966>: The deprecated mailcap module now refuses to inject unsafe text (filenames, MIME types, parameters) into shell commands to address CVE-2015-20107 <https://nvd.nist.gov/vuln/detail/CVE-2015-20107>. Instead of using such text, it will warn and act as if a match was not found (or for test commands, as if the test failed). <https://discuss.python.org/t/python-3-11-1-3-10-9-3-9-16-3-8-16-3-7-16-and-…>Python 3.12.0 alpha 3 Get it here, read the change log, sing a GPT-3-generated Sinterklaas song: https://www.python.org/downloads/release/python-3120a3/ <https://www.python.org/downloads/release/python-3120a3/> 216 new commits since 3.12.0 alpha 2 last month. <https://discuss.python.org/t/python-3-11-1-3-10-9-3-9-16-3-8-16-3-7-16-and-…>Python 3.11.1 Get it here, see the change log, read the recipe for quark soup: https://www.python.org/downloads/release/python-3111/ <https://www.python.org/downloads/release/python-3111/> A whopping 495 new commits since 3.11.0.

Possible re bug when using ".*"
by Alexander Richert - NOAA Affiliate Jan. 1, 2023

Jan. 1, 2023

In a couple recent versions of Python (including 3.8 and 3.10), the following code: import re print(re.sub(".*", "replacement", "pattern")) yields the output "replacementreplacement". This behavior does not occur in 3.6. Which behavior is the desired one? Perhaps relatedly, I noticed that even in 3.6, the code print(re.findall(".*","pattern")) yields ['pattern',''] which is not what I was expecting. Thanks, Alex Richert -- Alexander Richert, PhD *RedLine Performance Systems*

NoneType List

Dec. 31, 2022

Happy New Year, everybody! I'm new in the Python List, new in Python world, and new in coding. A few days (weeks?) ago, I faced a problem trying to write a program for an exercise. I asked for help and nobody answered. In the meantime, I found a part of the solution, but a part still remains a mystery for me. Please run this small snippet, and help. Thanks a = [1, 2] print() print("a ==", a) print("type(a) is", type(a)) b = a.append(3) print("\nb =", "a.append(3)") print("b ==", b) print("type(b) is", type(b)) c = ['1', '2'] print("\nc ==", c) print("type(c) is", type(c)) d = c.append('3') print("\nd =", "c.append('3')") print("d ==", d) print("type(d) is", type(d)) """ I mean: why b = a.append(something) is the None type, and how to make a new list that contains all the items from a and some new items? I wasn't able to solve it in a few hours :( Now I know: """ crta = '=' print('\n', 4 * ' ', crta * (len('The solution:')), sep='') print(3 * ' ', 'The solution:') print(4 * ' ', crta * (len('The solution:')), sep='') print('\nThe solution is the slice, an element of Python syntax that allows') print('to make a brand new copy of a list, or parts of a list.') print('The slice actually copies the list\'s contents, not the list\'s name:') print() a = [1, 2] print("a ==", a) print("type(a) is", type(a)) b = a[:] print("\nb = a[:]") print("b ==", b) b.append(3) print("\nb =", "b.append(3)") print("b ==", b) print("type(b) is", type(b)) print("\na ==", a) print('But I still don't know why "b = a.append(something)" is the None type.') print('Is there anybody out there?!')

set.add() doesn't replace equal element
by Ian Pilcher Dec. 31, 2022

Dec. 31, 2022

I just discovered this behavior, which is problematic for my particular use. Is there a different set API (or operator) that can be used to add an element to a set, and replace any equal element? If not, am I correct that I should call set.discard() before calling set.add() to achieve the behavior that I want? -- ======================================================================== Google Where SkyNet meets Idiocracy ========================================================================

On a superficial level, the answer is: "Because > PyCapsule_GetPointer uses NULL to indicate failure." Makes sense, too. Thanks.

Why can't the pointer in a PyCapsule be NULL?
by Robert Latest Dec. 30, 2022

Dec. 30, 2022

Hi all, the question is in the subject. I'd like the pointer to be able to be NULL because that would make my code slightly cleaner. No big deal though.
