I'm following the guide here:

Python3 Urllib Tutorial

Everything works fine for those first few examples:

I'm learning python, now I'm learning for and while, the exercise that I'm doing asks me to make the square of a number using a for loop. So I'm trying to make it but I don't know how to solve a problem, that I know why it is there, but I don't know how to solve it.

Anyway here's the code

Does someone have a solution to get a Azure Key Vault Secret from a VMSS Instance? For a single VM I found this article: https://docs.microsoft.com/en-us/azure/key-vault/tutorial-python-linux-virtual-machine#create-edit-and-run-the-sample-python-app

Can I do something similar like that for a VMSS Instance? With the Python Script from the Microsoft Documentation I have the following issue. I can't reach the Key Vault URL from the Instance with this Request. (Request Timeout.)

I'm trying to return BeautifulSoup search results based on a div id match, but the first (and only) result is giving me the the HTML structure without any of the data. I would like to return back both the structure AND the data, so I can continue with my tutorial/parsing and eventually pull out the individual data elements (e.g., name of the search result, description of the search result, etc.).

Context: This is part of an exercise I'm working on to learn BeautifulSoup, so very new. Have taken a look at BS documentation and have not found anything that is helpful to me given my level of knowledge.

Using this tutorial (https://www.dataquest.io/blog/web-scraping-tutorial-python/), I have tried to write a fairly straightforward bit of Python code to capture the search results on this page: http://www.ncsl.org/searchresults/issearch/false/kwdid/463.aspx. I am trying to use BeautifulSoup to collect the various elements of each search result.

The code snippet should speak for itself, but basically I am trying to:

• Match where div id = "search results" (i.e. the section of the page's HTML that I'm interested in).

• Pull in every search result (in my knowledge, that should just be a matter of finding where class = "article" given that this uniquely identifies the search results.

Instead, I am getting:

• HTML structure code that closely mirrors the structure of the elements that I am trying to pull in, but doesn't have the actual data. It looks like this:

I'm trying to train a deep Q-learning Keras model to play CartPole-v1. However, it doesn't seem to get any better. I don't believe it's a bug but rather my lack of knowledge on how to use Keras and OpenAI Gym properly. I am following this tutorial (https://adventuresinmachinelearning.com/reinforcement-learning-tutorial-python-keras/), which shows how to train a bot to play NChain-v0 (which I was able to follow), but now I am trying to apply what I learned to a more complex environment: CartPole-v1. Here is the code below:

I would like to display / print my sqlalchemy classes nice and clean.

In Is there a way to auto generate a __str__() implementation in python? the answer You can iterate instance attributes using vars, dir, ...:... helps in the case of simple classes.

When I try to apply it to a Sqlalchemy class (like the one from Introductory Tutorial of Python’s SQLAlchemy - see below), I get - apart from the member variables also the following entry as a member variable:

_sa_instance_state=

How can I avoid that this entry appears in the __str__ representation?

For the sake of completeness, I put the solution of the linked stackoverflow question below, too.

I followed this azure example to develop my module connectedbarmodule in python for Azure IoT Edge. Then , I followed this link to deploy my module in my device (raspberry pi 3). However, my module can't be downloaded. Then, I executed the following command on my device :

I downloaded cx_Freeze because I'm trying to make a .exe file to share with my platoon and I've been reading through the docs as well as scrolling through cx_Freeze tutorial. After following both of those I still don't know why this isn't working for me. I'm on Python 3.6.2 and I have the path directly setup to the command line.

I tried to launch with setup.py and Julian date 2.py on the desktop and I tried adding them to same folder, but no matter what I try I get back this error when I type python setup.py build, python: can't open file 'setup.py': [Error2] no such file or directory or file exsists. Below is my setup.py code.

I am new in python and I am so sorry if my question is very basic. In my program, I need to pars an html web page and extract all of the links inside that. Assume my web page content is such as below:
