QUESTION
I scrape some data on website, here's my script :
...ANSWER
Answered 2022-Mar-12 at 11:31"My goal was to : if needed execute try, else execute except."
This is exactly what it's doing. I'd suggest look into how to debug code. You would be able to run it line by line, and follow the logic and you would see what is occuring.
When you do try/except, it "trys" to execute the script in the try block. If it's successful, it skips the except block. If it fails at some point within the try block, it then goes and executes the exception script.
The reason it APPEARS to be running both is because, technically, as I described above, it does run both. You are seeing this print twice because of the placement of your print() statements.
It enters the try block, then prints i with print(i) right at the beginning. At some point in the try block after the print(i), an error/exception is raised, and then it goes to the except block, where again, it prints i with print(i) at the beginning of that block.
If you want it to look for a condition and only execute the one you want, then you need to use if blocks to check for a condition, not a try/except.
With that being said, it would be far more efficient to get the data from the source as opposed to rendering with Selenium. You also get far more data. I don't know what exactly you would want from the response, but this is what you'd get: click here

QUESTION
To give more context about my problem:
I am using python to build an API connecting to the TWS of interactive brokers. I managed to build something functional and able to fetch live data from contracts using the methods given in the doc of IB. Now that I want to use all the data to build other parallel systems with it, I have encounter problems organising the data that arrives from the IB server.
My program loops a list of 30 symbols to get live data from and then I want to put the data (ex. 'HIGH', 'LOW', 'CLOSE', 'VWAP' etc) from each symbol all together in one dataframe to calculate indicators and from there come up with an alert system that is based on them indicators.
This objective I have already accomplished it using only one symbol for the whole program. Is easy to store the data in instances or variables, pass it to a DataFrame and then calculate to set up alerts.
Now when looping a list of 30 values and receiving the data of all of them I have struggled trying to store the data for each symbol together and then calculate and set up alerts. Specially when I have to use several methods to receive the data (ex. I use tickPrice for some data and tickString for some other data) this several methods execute themselves one after the other but they wont necessarily have all the data at the same time, some values take more time than others to show.
I will show an example of my code to give even more context of my objective:

QUESTION
I have two sets of dataframe, one is the "gold" one which means that I need to keep all the rows for the gold one after merging. The other one is reference one. Below is a sneak peek of that two dataframe.
...ANSWER
Answered 2022-Feb-17 at 08:59I have the answer you want here. It generates an "output.csv" which you can read with pandas as a dataframe to give you the expected result.
Here is my "output.csv". The results look odd because your sample input (reference.csv and gold.csv) were a small subset. If you test on your full large input CSVs, you will get a proper output:

Answered 2022-Feb-08 at 17:40You would need to override the toString() for HashMap, that's a bad way to do it. Create your own printMenu() method to iterate yourself. I'd also remove the new lines from your options.

QUESTION
I'm working with British Election Study data. To be used in R, this first has to be converted from the .dta form provided, which I think puts labels on to a lot of variables. Most of the time this is useful, but I think a problem I've got is where this isn't the case.
Using as_factor() blindly converts all variables with labels to factors. Is there a way to specify that only certain vectors are converted ? i.e

I am currently working on the BNP Paribas Cardiff Claim Management dataset from kaggle & I have finished writing my code on python (jupyter notebook) for the train dataset where I have used 20% of it to test. This study requires me to test my model on a completely different dataset test.csv and append the predicted probabilities on the sample_sumbission.csv. How do I go about it. What changes would I have to make since I have made many tweaks to the training dataset using feature selection techniques

QUESTION
Disclaimer: I have minimal experience with R, though am familiar with programming in general. All examples were run in RStudio using version 4.0.2 of R.
I am using a package called gsynth to conduct an analysis on some political data. I have a data frame named vdem5 with five variables: country, corruption, democracy, bnp and eu (eu is dichotomous/binary, indicates eu-memebership). I have tried using gsynth in accordance with their example page as such:
ANSWER
Answered 2021-Apr-02 at 15:15I managed to resolve the problem myself by adding more units (aka countries), though the exact reason it failed before is still not clear to me. I've posted an issue on the gsynth github page, recommend anyone struggling with this later on to check it out.
UPDATE:
It turned out that the cause of the problem was the CRAN version of gsynth, removing this and installing vis devtools:
devtools::install_github('xuyiqing/gsynth')
solved the issue!

Install bnp
You can use bnp like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
