Please see the [VNS Homepage] for more information about VNS. This repository contains the VNS simulator, VNS web interface, and a command-line client for altering and interacting with topologies while they are running.

How can I convert a list to JSON/dictionary - Python

Asked 2021-Dec-27 at 12:22

I am having some problems manipulating an answer.

I would like to manipulate a dictionary, because it is simpler for what I need.

To leave it in context basically what I am trying to do is get the status related to the modules that I need.

As you can see it returns the status of many modules, but I need only a few.

This is my code so far:

Asked 2021-Aug-03 at 22:09

I'm attempting to transpose a row into a new column using the pandas dataframe. Visit ID is the unique identifier. I used df.pivot and df.melt but df.melt seems to do the opposite. I'm pretty new to Python and I gave it a start but I'm pretty lost. Any suggestions?

Need help some with simple python find in strings

Asked 2020-May-31 at 18:58

I'm a newbie coder and I need some help with the xxx.find usages...

Summary

I am doing a web automation project with selenium. This python project's main goal is

Step 1. To login into my school's LMS website automatically with provided username and password

Step 2. Get the page_source of a given website URL which my school hosts all the assignment PDF files

Step 3. Do a matching search of PDF viewer links on the page_source string

Step 4. Navigate to the matching PDF viewer URL and get the page_source again

Step 5. Search for var DEFAULT_URL = '/icom/files/b729266c557f5f7108894ade1668d55a.pdf' or relevant links which is the link that my school server hosts the pdf file

Step 6. Get the value /icom/files/xxxxxx.pdf and combine with a header like www.icom.org.cn/ so they become www.icom.org.cn/icom/files/xxxx.pdf

Step 7. Then perform a wget command or something to get the pdf file.

The problem now

I somehow got the login automation correctly but now stuck at the page_source matching process but somehow stuck at Step 3

After getting onto the website URL where my school hosts all PDF assignment.

I ran a sauce = driver.pages_source and I am trying to match it by

If I got your question right, you need some logic for string matching.

This is a possible approach to do so.

You check if a string is in another and proceed with your logic, otherwise you can define some excepts.

Add a static function to your enum, call it getPlanetByName(String name). The function should iterate through Planet.values() and return the one with the specified name. Then, as soon as your user enters a planetName, you store it into

Device Orientation API not working with local webserver

Asked 2020-Jan-08 at 10:36

While working with the Device Orientation API I noticed something strange.

The following online demo works perfectly (except for "compassneedscalibration"): https://www.audero.it/demo/device-orientation-api-demo.html

But when I clone the Soucecode locally and provide the Web page via a local Web server^* the API seems to not be available anymore. Although using the same browser tab. Also no Messages, warnings or errors appear in the JavaScript console.

The Web page states:

deviceorientation event not supported
devicemotion event not supported
compassneedscalibration event not supported

Am I doing something wrong? Or is this an intended behavior or a bug? I will need to provide my web app by a local web server.

I am using "Chrome 79.0.3945.93" on "Android 7.1.1;VNS-L21 Build/NMF26V"

I found out that you need to provide the wep page via an Encrypted HTTPS connection on order to access the Device Orientation API and also some mediaDevices.

A simple way of providing HTTPS pages during development (not production) is this simple python webserver:
