kandi X-RAY | TWC Summary
C Code to talk to the Tesla Wall Connector Gen2 (EVW2T32HL) over the RS-485 port used for load sharing communication. This is based on works from and data posted in the Wall Connector load sharing protocol thread at TWCManager is written in python and is not as suitable for porting to embedded microcontroller systems. My aim is to eventually port this code to the ESP32/ESP8266. Currently the code runs on Linux (Tested on ubuntu 19.10) and the Raspberry PI using an FTDI based RS-485 adapter. TWC is running firmware version 4.5.3. Has no support for earlier firmware versions with different packet lengths.

QUESTION
I am trying to scrape weather form weather.com but it is not working for some reason here is the error:
...ANSWER
Answered 2021-Nov-10 at 05:00A couple of things:
As noted in comments your first soup.find is returning None hence error. Looking at the relevant title there are dynamic parts to the class names. I would instead use an attribute = value css selector, with starts with operator, to target the class attribute by substring. I would also add in the h1 type selector, thus ensuring to target the h1 directly without chaining calls.
Avoid using variable names which are already either key words or python in-builts i.e. all().
A re-write thus might look like:
QUESTION
I have a json
coming back from an API that I am appending to a list. After I finish making that call I need to flatten that data using pandas. I'm not sure how to do.
Code:
...ANSWER
Answered 2021-Jan-05 at 18:35- Because the desired result is for the data from each
dict
in the'icdcodes'
key
to have a separate row, the best option is to usepandas.json_normalize
. - First create the main dataframe and use
pandas.DataFrame.explode('icdcodes')
, which will expand the dataframe to have the appropriate number of rows for each'clientid'
based on the number ifdicts
in'icdcodes'
. - Use
.json_normalize()
on the'icdcodes'
column, which is alist
ofdicts
, where some thevalues
may also bedicts
. .join
the two dataframes and drop the'icdcodes'
column- Use
pandas.DataFrame.rename()
to rename columns, andpandas.DataFrame.drop()
to drop unneeded columns, as necessary. - Also see this answer from SO: Splitting dictionary/list inside a Pandas Column into Separate Columns

QUESTION
This is a stochastic problem. When I re-make my project, this problem is more likely to happen. I used gdb core dump analysis and found out that cv::namedWindow
function may be the reason?
This is main.cpp
...ANSWER
Answered 2020-May-19 at 08:42You should not open a cv::namedWindow
from a thread that isn't the main thread. It might work, but I wouldn't recommend it.
QUESTION
how do i get a list all customers who have the sequential letters ‘co’ in the customer name.List must include the customers’ ID, names and ordered by their names in ascending.
i have provided a table and content to create for customers and want to list the names which have sequential letter 'co' in then
...ANSWER

might be one option; I presumed that you want any "co" string, regardless its letter case (that's why I used lower
function). If you don't need it, remove it.
QUESTION
I want to create a text (Ultimately in epub/pdf but first in html and then I'll convert it) where under every word there is a translation for that word, just smaller. Here is a picture of what the goal is: image
My current solution is to put two words together in a div, each word in it's own p, I then apply styles to that to get it to be all in-line, the upper word bigger than the translation and so on. Here is what a word would look like:

Answered 2020-Apr-21 at 21:37Your solution is absolutely fine. You won't make it much better if you want to rely on auto width, which you do. I would just replace

QUESTION
New to VBA and going in circles trying to extract data from a table on a webpage that only appears after it is clicked.
I'm using a VBA macro within excel to pull data from a weather.com:
- I can successfully extract elements from the visible table.
- I'm pulling Error 91 when trying to pull the "sunrise" and "sunset" time from the hidden menu.
- I would like to extract the time of sunrise and sunset from the 2nd day on the table.
Question:
- Is there a way to click within the code to reveal the data I want to extract?
- This data is located within a SPAN in the source code - Can I be extract this innerText from the closest ClassName to the SPAN in question?
Would somebody mind taking a look at the code and helping me out? Thanks!
I can successfully extract "day", "weather", and "temp" but cannot pull "srise".
Here is my VBA code:
...ANSWER
Answered 2020-Mar-11 at 11:26You've done a good job so far, +1 for the effort you've put in this!
I would like to take it one step further, if you don't mind.
Firstly, you have to keep in mind that what you see when you inspect an element in your browser's developer tools is not necessarily what you'll see in the source HTML of the page.
Indeed, in this case if you actually right click and view the source code of the page, you will not find the HTML snippet that you posted. You will find it however if you inspect the element of interest.
This happens because this part of the HTML code is generated by a script. You will find this script in the Page's source code inside a tag (just search for "sunrise" for example). This tag contains a huge string and a second small one, both in JSON format.
The script
tag looks like this:
I have replaced most of the string with ...
for the sake of readability.
All the data you need is in the first JSON string (window.__data
) between the curly brackets {...}
. You will not be needing the second string (window.experience
).
So basically what you need is to isolate this string from the response and then parse it to get the info you want.
You can inspect the JSON string's structure using a tool like this. Here's how it looks like:
To parse a string like this you will need to add this JSON parser to your project. Follow the installation instructions in the link and you should be set to go.
You will also need to add the following references to your project (VBE>Tools>References):
