QUESTION
I have a drop down single select combo box. I can get a reference to that drop down via a CSS selector.
...ANSWER
Answered 2022-Apr-14 at 14:27find_all() should return you all the desired WebElements and the subscription [0] should get ou the desired element.
Effectively, your code block will be:
drop_down = find_all(S(".single-option-selector.no-select.selector.single-option-selector-100"))[0]
select(drop_down, "23.0cm")

I have to sketch out the periodic table with ten elements through a list like the following one:
...ANSWER
Answered 2022-Mar-08 at 13:15Since you use tabulate, there is a solution to modify your code by:
- Adding an extra row full of characters of specified size for each column at the end the array
- Calling
tabulateincluding specification of the alignment usingcoalign - Remove the extra row
Since the output is a string, the width of the columns is not associated with any measure e.g. in cm, so you will need to define a length scale that suits your needs, i.e. the number of characters per required width unit.
Note that 2 characters are removed from the computed width to account for the inner column margins which are 1 character left and right.
QUESTION
I've been struggling with the Apache Zeppelin notebook version 0.10.0 setup for a while. The idea is to be able to connect it to a remote Hortonworks 2.6.5 server that runs locally on Virtualbox in Ubuntu 20.04. I am using an image downloaded from the:
https://www.cloudera.com/downloads/hortonworks-sandbox.html
Of course, the image has pre-installed Zeppelin which works fine on port 9995, but this is an old 0.7.3 version that doesn't support Helium plugins that I would like to use. I know that HDP version 3.0.1 has updated Zeppelin version 0.8 onboard, but its use due to my hardware resource is impossible at the moment. Additionally, from what I remember, enabling Leaflet Map Plugin there was a problem either.
The first thought was to update the notebook on the server, but after updating according to the instructions on the Cloudera forums (unfortunately they are not working at the moment, and I cannot provide a link or see any other solution) it failed to start correctly. A simpler solution seemed to me now to connect the newer notebook version to the virtual server, unfortunately, despite many attempts and solutions from threads here with various configurations, I was not able to connect to Hive via JDBC. I am using Zeppelin with local Spark 3.0.3 too, but I have some geodata in Hive that I would like to visualize this way.
I used, among others, the description on the Zeppelin website:
https://zeppelin.apache.org/docs/latest/interpreter/jdbc.html#apache-hive
This is my current JDBC interpreter configuration:
...ANSWER
Answered 2022-Feb-22 at 16:53So, after many hours and trials, here's a working solution. First of all, the most important thing is to use drivers that correlate with your version of Hadoop. Needed are jar files like 'hive-jdbc-standalone' and 'hadoop-common' in their respective versions and to avoid adding all of them in the 'Artifact' field of the %jdbc interpreter in Zeppelin it is best to use one complete file containing all required dependencies. Thanks to Tim Veil it is available in his Github repository below:

QUESTION
I'm trying to do a guassian fit for some experimental data but I keep running into error after error. I've followed a few different threads online but either the fit isn't good (it's just a horizontal line) or the code just won't run. I'm following this code from another thread. Below is my code.
I apologize if my code seems a bit messy. There are some bits from other attempts when I tried making it work. Hence the "astropy" import.
...ANSWER
Answered 2022-Jan-27 at 16:34There are two problems with your code. The first is that you are performing vector operation on list which gives you the first error in the line mean = sum(wavelengths*intensities)/n. Therefore, you should use np.array instead. The second is that you take math.exp on python list which again throws an error as it takes a real number, so you should use np.exp here instead.
The following code solves your problem:
QUESTION
I have a dataframe that has multiple tables with 1 or 2 empty rows in between. I want to split based on empty rows.
There are 3 tables here. As you can see, row no. 4,5, 13,14 are blank on which the split must happen.
ANSWER
Answered 2022-Jan-26 at 13:46I think in your example the rows are not NaN, it seems they're having an empty string.
Plese try the following code:
QUESTION
This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.
I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.
As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.
I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...
If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.
...ANSWER
Answered 2022-Jan-12 at 01:03You can shuffle the shortQuizPrompts array before starting the quiz. Array shuffle details can be found in this answer.
