QUESTION
I am using Perl 5.34.0 and I want to find wether an input is only hebrew letters and some signs like the question mark, etc. Even though I found a solution with a lot of overhead, I would like to learn how to do it simpler with regular expression.
This is my solution without regular expression.
First I defined the Hebrew characters in a constant hash in a Perl module.
...ANSWER
Answered 2022-Mar-24 at 20:47You can use a relatively simple pattern match to do this.
The interesting bit here is the \p{Hebrew}
, which allows you to match every character with a specific Unicode property. The rest is just beginning ^
and end $
of string, and a quantifier +
to say one or more.

Answered 2022-Mar-13 at 12:18You can easily just use a set
data type in python and you can use a loop that goes inside the Dict file and goes one by one and appending(using the update()) it to a set variable, sadly I'm too lazy to write the code that will solve your problem but you can read more on sets and write your code(

ANSWER
Answered 2022-Feb-21 at 16:56The data you are looking for is loaded via javascript so to gain access to the data you will have to pre-render the page using either scrapy-splash
, selenium
or scrapy-playwright
. You can then use below xpath selector to obtain the urls. No need to use regex in this case
QUESTION
I'm currently learning Elastic, I've created this dataset on french presidentials elections from 1965 to 2017 and I want to query the sum of all the documents matching "tour" = 1 and "election" = 1974.
I've done this, but it's not working, what I did wrong ?
...ANSWER
Answered 2022-Feb-13 at 12:25You can use a combination of the search query with aggregations
You need to use a boolean query to find all the documents matching "tour" = 1 and "election" = 1974, and then use sum aggregation to find the sum of blancs_nuls
field on the matching documents
QUESTION
The following error is given when I try to deploy a simple app (the default one that IntelliJ provides when you create a new Java EE Web App project):
...ANSWER
Answered 2022-Feb-08 at 19:36You are using Java 16 (as shown in the log file) with Maven. In this case, you should use TomEE in version 8.0.9 as this release contains important fixes regarding illegal reflective access (due to the use of Unsafe for proxy creation) in higher versions of Java. You find some details in https://issues.apache.org/jira/browse/TOMEE-3795
It looks like you are using a lower Java version for running your standalone TomEE deployment, which works as it isn't as restrictive as newer Java versions.
Side Note: Java 16 is end-of-life and you should better switch to Java 17.
QUESTION
I'm trying to do a circuit consisting of a 2 to 1 multiplexer (8-bit buses), an 8-bit register and an 8-bit adder. These components are all tested and work as expected.
The thing is: if I try to send the output of the Adder to one of the inputs of the multiplexer (as seen in the image by the discontinued line), the simulation will stop rather suddenly. If I don't do that and just let ain do its thing, everything will run just as it should, but I do need the output of the adder to be the one inputted to the multiplexer.
The simulation is the following:

QUESTION
Any advice for selecting columns in a cursor when the db column names are poorly designed with hypens in them. I agree the column's names with hyphens are a poor design but this was set up this way 10 years ago by someone else. Here is an example where the field time_offer_changed
works fine but sellker-sku
does not. I can select them by the their raw position - row[6]
but would like to find something a bit easier to follow for someone who might touch this code later
ANSWER
Answered 2021-Dec-06 at 02:54Either change the cursor to return a dictionary and access it via r['seller-sku']
or if that's not possible/desirable then you can always use sku_seller_sku = getattr(r, 'seller-sku')
