kandi X-RAY | Grapes Summary
Grapes is kind of Regular Expression to make string comparision faster. Let's understand it with some examples;. Currently 3 types of matcher are supported. These are the 3 matchers I intially created. But you can create your own matchers of different features. Moreover, currently they accept char[] as input. But you can create them to accept byte[], list etc. to make them more fast. One of the sample matcher I have created under the matcher package.

QUESTION
This is not a Duplicate question, I spent 3 days searching here and there is no other question similar to mine!
This javascript generates random words only when called from one single div, or the first one when trying different DOM Methods to get Elements.
I've tried several options and combinations with getElementsBy ID, Tag, Name, Class, and CSS Selector.
However after several days searching and testing, I can't make it work in more than one div.
I need to use the same array as the only source for all my 36 divs, to generate random words from an onClick event on each of them.
I'm open to edit it, or completely change it.
This is what I have currently working for the first div using getElementsByClassName which I suppose should be the correct way as I need to call this script from several elements, not just one:

QUESTION
If there are any cells with a comma (if condition), I would like to separate them out and pick the last one, something like:
The original table is like here below:
index x1 x2 0 banana orange 1 grapes, Citrus apples 2 tangerine, tangerine melons, pearswhich is going to be changed to like below:
index x1 x2 0 banana orange 1 Citrus apples 2 tangerine pearsAs you can see, for each cell the second fruit name was selected by iterating over all cells in dataframe.
In order to do that, I would like to use apply with a function that separates by comma, but please let me know if there's a better way to do that.
Thanks.

I'm trying to generate some data for testing by duplicating existing data in my database. There are a number of tables linked by FKs and I want to keep the same data profile. I think it's easiest to explain with an example:
CustomerID Name Age 1 Fred 20 2 Bob 30 3 Joe 40 InvoiceID CustomerID Date 1 1 2020-01-01 2 2 2020-02-02 3 2 2020-03-03 4 3 2020-04-04 LineItemID InvoiceID Item Price Qty 1 1 Apples 1.5 5 2 2 Oranges 2 3 3 2 Peaches 2.5 6 4 3 Grapes 3 10 5 4 Pineapple 5 1I want to duplicate all the customers who are older than 18, including all of their linked data.

QUESTION
I am using pandas to import a dataframe from excel in order to sort, make changes and run some simple addition and division on the data.
My code is working but it has global variables throughout. I think this is poor practice and I want to somehow eliminate these global variables but I am confused on how I can go about doing this.
I'm not sure how I can further modify my dataframe with indexing and slicing without declaring global variables.
...ANSWER
Answered 2021-Jun-07 at 06:55There are several things you could do, dependent on the overall structure of your code and your goal. Without knowing more about your case and, for example, seeing how the snippet you provided is embedded into the rest of your code, those are only possible solutions.
You could define a function, make it take a dataframe as an argument, perform operations on it and then return the modified dataframe. The function could also simply take a filename as argument, so that the respective df is created within the function to begin with. If you do not need to refer to intermediary variables such as new_indexes
or sliced
later in the code, using a function to perform the operations might be a good way to go.
You could also define a Class, make the variables into properties of objects of that class and write methods to perform the respective operations you want to do. This would have the advantage that you could still access your variables, if necessary.

QUESTION
See code below and log. I am working on a google sheets script that updates a google sheet when a linked google form is submitted. To do this I am using the array "event.namedValues", which is generated automatically when a form is submitted. However while debugging some issues (and learning how to do this), I wanted to check the length of the array I was working with and it would return "null". When I tried adding the .length property of the array to 0, the logger logged "NAN" (See log below). What am I doing wrong?
Code Sample:
...ANSWER
Answered 2021-Jun-03 at 22:59Since e.namedValues is an object, it does not have a length property.
