I have installed Python 3.4.4 on XPSP3 and am trying to work my way through this tutorial. 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

What about introducing a method for text streams that reads the lines from the bottom? Java has also a ReversedLinesFileReader with Apache Commons IO.

Python Question re Executing a Script
by Brent Hunter May 1, 2022

May 1, 2022

Hello, I just purchased a new Windows 11 computer and installed Python 3.10.4 (64 bit). I can't figure out from your documentation, how do I: 1. Run a python script that is located in the same directory ( C:\Users\Brent\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.10 ) 1. How do I automatically run a python app at Windows startup? Thank you! Brent Hunter

Run a python script that is located in the same directory ( C:\Users\Brent\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.10 ) > ONE: that path indicates that you installed Python "for current user only". TWO: that is the path for the short cut entry that shows up on the Windows "Start Menu" (whatever that looks like on Win11). It is NOT a location for user scripts. Python, at heart, is a language interpreter that is invoked from a command line shell. (Use <ctrl-z> to exit the interpreter if you are trying the below examples -- otherwise you'd add the path/name of the script file to the command line) -=-=- Microsoft Windows [Version 10.0.19044.1645] (c) Microsoft Corporation.

Scripts written using one of the graphical libraries (Tkinter, wxPython, etc.) are typically given a .pyw extension -- .pyw is normally associated with an alternate start-up module which suppresses the console window. Editing of scripts can be done with one's favorite programming text editor. If one can't live without having some sort of IDE, look for something called IDLE to be on your start menu (IDLE is actually a Python script using Tkinter). > > 1. How do I automatically run a python app at Windows startup? Short answer: the same way you would run ANY application at start-up. Longer answer: this is a feature of the OS, not Python.

Printing Unicode strings in a list
by Stephen Tucker April 30, 2022

April 30, 2022

Hi PythonList Members, Consider the following log from a run of IDLE: ================== Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)] on win32 Type "copyright", "credits" or "license()" for more information. >>> print (u"\u2551") ║ >>> print ([u"\u2551"]) [u'\u2551'] >>> ================== Yes, I am still using Python 2.x - I have good reasons for doing so and will be moving to Python 3.x in due course. I have the following questions arising from the log: 1. Why does the second print statement not produce [ ║] or ["║"] ? 2. Should the second print statement produce [ ║] or ["║"] ? 3. Given that I want to print a list of Unicode strings so that their characters are displayed (instead of their Unicode codepoint definitions), is there a more Pythonic way of doing it than concatenating them into a single string and printing that? 4. Does Python 3.x exhibit the same behaviour as Python 2.x in this respect? Thanks in anticipation. Stephen Tucker.

Instatiating module / Reusing module of command-line tool
by Loris Bennett April 29, 2022

April 29, 2022

Hi, I have a command-line script in Python to get the correct salutation for a user name in either English or German from a 'salutation server': $ get_salutation alice Dear Professor Müller $ get_salutation alice -l de Sehr geehrte Frau Professorin Müller The hostname, port, user and password for the 'salutation server' can be given as options on the command-line, but if omitted are read from a configuration file. The program is implemented in two modules without any classes: main.py: ... parse command-line options, read config file ... salutation = my_mailer.salutations.get_salutation(args.user, args.lang, args.host, args.port, args.user, args.secret) salutations.py def get_salutation(uid, lang, host, port, user, secret): ... I have another program that is intended to run as a cron job and send an email to certain users. This is implemented as a number of modules without any classes and will need to use the 'get_salutation' function from the first module. My question: What is the analogue to initialising an object via the constructor for a module? My understanding is that a module is a singleton of the class 'module'. So do I just write a method which reads the config file, or is there some more standardised way which corresponds to instantiating an object via my_object = MyClass() in the case of a class. Cheers, Loris -- This signature is currently under construction.

Testing an app protected by Okta authorization code with PKCE flow
by George Fischhof April 29, 2022

April 29, 2022

Hi Folks, has anyone of you a working solution for testing an app protected by Okta authorization code with PKCE flow? Meaning to get a bearer token? I saw / read several articles about it on the net, and several hacks (that is not problem now ;) ), but it seems that neither of them works with Okta. We are using Okta's .net backend stuff and Angular widget BR, George
