QUESTION
How do I scrape a value that is generated within Javascript.
I have been trying to figure this out for a few days and now I'm stuck. I have the page login stuff working.
The page looks like this in a browser and I want to extract the SoC% value and nothing else. In this example the value is 92.16%
This page will auto update every 10 minute.
I can see the part of the JS that returns the value but I don't know how to scrape this value into a variable in my script.

I need help on populating some input fields on a form with Vue 3. When a user selects an option in my dropdown the form should output the necessary inputs. Instead it will show all inputs from every option.

QUESTION
First time poster, so I apologize if I don't do things correctly. I am also new to React so bare with me, I will do my best to describe the problem.
I have a dataset that consists of school classes in json format. I am using axios to grab the data. The data consists of an array of objects which contains information about each class. I want to break up the classes so that they are separated into 4 different arrays based on what school year you are in (freshman, sophomore, junior, senior). I then want to display these classes on my web app.
Here is the code below:
...ANSWER
Answered 2022-Apr-03 at 22:32You must not modify the states directly as you are trying with freshman.push(item)
, instead use setFreshman([...freshman, item])
But in your case, this won't work because the app only updates the states after all forEach loop, so it will keep getting the initial state (the empty array) from the states and adding the current item, the only one in the end.
So one solution is using temporary variables to keep the items and once forEach has finished you update the states.
QUESTION
I'm trying to plot the Bode plot of an FIR filter which is used to reject unwanted frequencies over 100 Hz with a sampling frequency of 500kHz. The filter has many coefficients in order to produce as much cleaner output as possible but the error message when trying to construct the Bode plot refers to badly conditioned coefficients.
I tryied to reduce the number of coefficients from 100000 to 2000 (numtaps_2 in the code below) but this also didn't work and I got the same error message.
Error message : /home/goodvibrations/.local/lib/python3.10/site-packages/scipy/signal/_filter_design.py:1709: BadCoefficients: Badly conditioned filter coefficients (numerator): the results may be meaningless warnings.warn("Badly conditioned filter coefficients (numerator): the " /usr/lib/python3.10/site-packages/numpy/lib/polynomial.py:779: RuntimeWarning: overflow encountered in multiply y = y * x + pv /usr/lib/python3.10/site-packages/numpy/lib/polynomial.py:779: RuntimeWarning: invalid value encountered in multiply y = y * x + pv /home/goodvibrations/.local/lib/python3.10/site-packages/scipy/signal/_filter_design.py:188: RuntimeWarning: invalid value encountered in true_divide h = polyval(b, s) / polyval(a, s)
...ANSWER
Answered 2022-Mar-26 at 15:27The answer for the question above is that when a large FIR filter is constructed the signal.freqz() function has a lot of error and the FFT approach is recommend.
Notes
Using Matplotlib's :func:matplotlib.pyplot.plot
function as the callable
for plot
produces unexpected results, as this plots the real part of the complex transfer function, not the magnitude.
Try lambda w, h: plot(w, np.abs(h))
.
A direct computation via (R)FFT is used to compute the frequency response when the following conditions are met:
An integer value is given for
worN
.worN
is fast to compute via FFT (i.e.,next_fast_len(worN)
equalsworN
).The denominator coefficients are a single value (
a.shape[0] == 1
).worN
is at least as long as the numerator coefficients (worN >= b.shape[0]
).If
b.ndim > 1
, thenb.shape[-1] == 1
.
For long FIR filters, the FFT approach can have lower error and be much faster than the equivalent direct polynomial calculation.

QUESTION
I'm struggling with the Linux tool "iptables". Following situation: I have a RaspberryPi running with HASS (Home Assistant) connected via ethernet. Now I want to add my inverter to home assistant, but this needs to be done by using his own WiFi network. So I need to forward requests to IP 11.11.11.1 (only this IP, not all trafic) to the wifi network.
Is that doable with iptables? Meaning defining a rule which says "target is 11.11.11.1, so lets put this to the wifi network".
I'm actually not sure whether iptables can do that or not. I read soming about nginx, but not sure how this would work.

QUESTION
I have a Javascript file that enables drop down menus dynamic (i.e. a selection from one drop down impacts the others). I would like to use this file in conjunction with multiple forms but I have hard-coded the starting variables in this file to html elements 'inverter_oem' and 'inverter_model_name'.
In other forms, I will need to reference different objects.
How can I accomplish this? I would like to create the variables in Javascript this way:
...ANSWER
Answered 2021-Dec-29 at 10:11Jinja does not know that you want to pass a variable inside a JavaScript environment, so it cannot add the quotation marks automatically around a string variable. It just replaces {{ var }}
with value1
causing a syntax error. Just add the quotation marks and then you can access myVar
inside the JS environment:
QUESTION
I am making a simple app that gives the user in depth information on a specific aircraft caution/warning when they press that specific button. I am pretty new and this is probably a very basic problem, but I simply don't know how to do it.
I'm not sure if the best way to organise the text data is to maybe put each caution/warning under its own string variable in a separate .py
file, or maybe make a class with different modules for each caution/warning with the module just being string info. Maybe a dictionary? Maybe the best way is to have it as a text file???
For each of the caution/warnings there will be approximately 200 words describing the problem associated with it and a solution.
A very short example of what I mean is: If someone pressed on the "Battery" caution, the button calls for the get_text
function in main.py
and sends it the button's id
. The get_text
uses that id
that was sent to it and then pulls the text from AOM.py
or .txt
or whatever. The information will then be displayed on the page and would be approximately 200 words about what the issue with the battery is and how to fix it. (I am purposely disregarding the need to change screens in my example here as I know how to do that). I'm just leaving as a print()
for now.
I have a min reproducible example here if someone could please help me out? Thank you very much.

Answered 2021-Nov-28 at 10:26I would keep it as dictionary
AOM.py
