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...

Here are snippets from my code, perhaps something will stand out to you? to = 'ed(a)domain.gov' cc = 'ed(a)gmailmail.com' bcc = 'ed(a)home.net' msg = MIMEMultipart() msg['To'] = to msg['Cc'] = cc msg['Subject'] = 'My Subject text here' msg['From'] = 'edsboss(a)domain.gov' smtp = SMTP("smtpserver") smtp.ehlo() smtp.sendmail(msg['From'], [to, cc, bcc], msg.as_string()) Thanks in advance..hope you're still out there!! ~Ed

When should I use "parent=None" in __ini__ and "parent" in super()
by Mohsen Owzar Sept. 2, 2022

Sept. 2, 2022

Hi Guys I'm writing since almost one-year codes in Python, using TKinter and PyQt5. I'm somehow able to writes GUIs in both of them. But since I'm using more Pyqt5 and using classes with initialization and super() constructs, and also I saw lots of videos and examples of coding them, I still don’t know exactly how and when should I use the parent in __init()__ and super() construct. For example, the following lines use "parent=None" in the __init__ construct and "parent" in the super() construct. And sometimes I do not see any of them in these two constructs. :::::::::::::::::::::::::::::::::::::::::::::::: class MyClass1(QWidget): def __init__(self, name, parent=None): super(MyClass1, self).__init__(parent) print(self.parent().test) :::::::::::::::::::::::::::::::::::::::::::::::: And sometimes without "parent" like the following: :::::::::::::::::::::::::::::::::::::::::::::::: class MyClass2(QWidget): def __init__(self, name): super(MyClass2, self).__init__() print(self.parent().test) :::::::::::::::::::::::::::::::::::::::::::::::: Could anyone explain this to me when and for which action I have to use the first one "MyClass1" and when the second one "MyClass2"? Regards Mohsen

I am not sure how different the two situations are. Ubuntu is presumably relying on the Debian security team as well as other volunteers and at least one company, namely Canonical. The sysadmins I know who are interested in long-term stability and avoiding unnecessary OS updates use Debian rather than Ubuntu, but that's maybe just my bubble.

googletrans in python
by Quentin Bock April 4, 2022

April 4, 2022

Can someone explain the basics of googletrans in python? I want to make a program that translates stories into English, but I'm not sure how to get a translation printed. Also, is this needed to be done in an HTML file inside python? If so can someone provide basic code for a translation and how that should be written and work? Thank you

How to detect an undefined method?
by Manfred Lotz April 2, 2022

April 2, 2022

Let's say I have a Python app and have used an undefined method somewhere. Let us further assume I have not detected it thru my tests. Is there a way to detect it before deploying the app? pylint doesn't notice it. Minimal example: #!/usr/bin/env python3 import logging from logging import Logger from random import randrange def main(): """ Below logger.err gives 'Logger' object has no attribute 'err' """ logger = logging.getLogger('sample') logger.setLevel(logging.DEBUG) handler = logging.StreamHandler() logger.addHandler(handler) num = randrange(0,1000) if num == 0: logger.err("got zero") else: logger.info(f'got a positive integer: {num}') if __name__ == "__main__": main() -- Manfred

Re: Exchange OWA using Python?

It expands to "Outlook Web App", period, (and more recently is called "Outlook for the Web"). That would explain why there is no documentation of an "API"... I get the impression that any so-called API programs have had to reverse engineer (maybe using things like WireShark) the HTTP communication. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed(a)ix.netcom.com http://wlfraed.microdiversity.freeddns.org/

asyncio+tkinter
by Skip Montanaro April 1, 2022

April 1, 2022

Given that both asyncio & tkinter are modules in the standard lib and both have event loops, I would have expected to find some "best practice" solution to mixing the two. I've not used asyncio, but might find it useful with the pynput module in the context of a Tk app. I see a few solutions out in the wild, but this seems like something which might best be addressed in either the asyncio or tkinter documentation, or better yet, implemented in one or the other.
