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...

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

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

Skip: being you a Python old timer, I think you are just grumbling for no good reason. :) Before anything else, people are already jumping into implementation details, optimization, syntax, etc. I am barely starting to look at whether there have been previous existing efforts, and if so, why were they discarded, etc. > > What exactly have you given me that I couldn't have done with > > x = 1 > x += 1 > I come back again to repeat it one more time: the compile() function already exists and works in Python. Before you do your posting, please think about the compile() function first. (Do I need to say it one more time? I don't mind.) So, let me try to pretend I am Skip Montanaro, and follow through with the process. (a) OK, I have been told that compile() function exists in Python. (b) I am complaining that I can do x = 1 x += 1 without resorting to codeblocks. So there is no need for codeblocks. Codeblocks are useless, good for nothing. (c) OK, one more time, I have been told that compile() function exists and works in Python. Everytime I talk about codeblocks, I need to think about the compile() function first. (d) Aha! So by analogy, there is no need for the compile() function in Python. I get it now! (e) Wait a second... searching through the Python newsgroup archive I find hundreds if not thousands of messages related to the usage of the compile() function. So the compile() function can't be useless. Either thousands of Python users are wrong, or I have not been careful in my thinking process. (f) Hmm... let me look at those messages and try to understand how people are using the compile() function. (g) Aha! The compile() function is not useless. I know how to use it, now. (h) Aha! Codeblocks are not useless. (i) Aha! So codeblocks are analogous to the compile() function, the only difference is that codeblocks are compiled at compile time. The compile function compiles the code string at runtime. (j) Wait, I think Hung Jung has said everything before in his messages. Bingo! Now you get it. Hung Jung

Hi there, I have done a lot of looking around online to find out how to convert Python files to .exe and .dmg files, but I am confused. Could someone provide pointers/advice as to how I can turn a Python file into a Windows .exe and Mac .dmg file. Thanks for any help.

Pickle file and send via socket
by S.B Feb. 18, 2022

Feb. 18, 2022

Hello friends Does anyone know if it's possible to pickle and un-pickle a file across a network socket. i.e: First host pickles a file object and writes the pickled file object to a client socket. Second host reads the pickled file object from the server socket and un-pickles it. Can anyone provide a simple code example of the client and server sides? Thanks

Greetings lists, I have started a newspaper (not newsletter) focused on interesting reads on Python mailing lists. Don't tag on the fact that holiday seasons are the worst times for launch according to marketing folks, I started this to note down interesting mails. This might also be a great way to bring mailing list gems to a wider readership. So, here's the url https://pyherald.com/ Kind Regards, Abdur-Rahmaan Janhangeer about <https://compileralchemy.github.io/> | blog <https://www.pythonkitchen.com> github <https://github.com/Abdur-RahmaanJ> Mauritius
