kandi X-RAY | koopa Summary
Koopa is a Cobol parser (generator). It can handle source files in isolation (no preprocessing required) and doesn't mind the presence of CICS/SQL fragments. The grammar is easily extensible in a way which minimizes the impact on the overall code.

QUESTION
I've cleaned and formatted some data. Among others, I have these columns: Name, Order Date, and Subscription (which has booleans).
How would you acheive this in pandas?
Example DataFrame:
...ANSWER
Answered 2020-Aug-03 at 06:08Customer churn is when existing customers stop doing business with you. This can mean different things depending on the nature of your business. Examples include:
Cancelation of a subscription
- Closure of an account
- Non-renewal of a contract or service agreement
- Consumer decision to shop at another store/use another service provider
Before you can figure out what your churn rate is, you need to decide how you’re going to quantify actions such as those above and agree on what defines customer churn for your business. Based on the sample data that you have shared, best bet would be to calculate, Total number of customers lost during a specific period. You need to define time frame to consider customer as Churned. For ex. Customer which have not purchased in past 30 days, 60 days etc based on the business you are looking at.

QUESTION
I am a new developer and currently learning dotnet core angular technologies.
I have a dotnet core project that allows me to download a SQL table as an excel file using EPPlus.Core library. When I test the code below, it works fine. I am able to get the excel file from my Downloads folder. However, when I publish it to the IIS, the code works fine but no files in the Downloads folder.
When I debug this, I realized that the frontend (in my case, it's angular) does not have access to my Downloads folder even though I explicitly declared in my controller. Here is my controller code that allows me to export as excel file.
...ANSWER
Answered 2018-Aug-15 at 12:55This will download the excel file inside the server's downloads folder. Instead of dealing with MemoryStream, I will use a frontend library. Since I have the list of participants in a JASON array form, DataTables library is a good one to go. It's not only to export excel, we can do pdf, print preview as well as a copy to the clipboard. I don't work for them. I have no affiliations with them. But I found it very useful in my case.
QUESTION
I'm trying to make a treasure hunt type game with Python and turtle
The goal is that a random step will be written on the screen the user will then use the arrow keys to follow the directions and press enter when done, then another step will be displayed
I'm coding it using trinket.io
I know that I have to have some way to stop the program but still allow the user to move the turtle with the arrows after each step but what I've tried so far hasn't worked.
Here is the program so far:
...ANSWER
Answered 2018-Aug-13 at 00:48I don't believe your code would work under the regular turtle that comes with standard Python. First, you tagged [python-3.x] but you use Python 2 style print statements.
But more importantly, your event logic is misguided. You shouldn't spin in a tight loop waiting for a turtle event:
QUESTION
I'm trying to generate random questions into a quiz. Currently everything is fine but the questions are repeating, how would you keep them from repeating? I've read several articles but I just don't quite understand how to implement the code.
...ANSWER
Answered 2017-May-10 at 04:02Here's a solution in JavaScript - you can follow the logic and the hopefully apply the concepts to your Java project. There's a running demo in this Plunkr https://plnkr.co/edit/KcHh63ou25LZDaZ79iwI?p=preview
Basically what we're doing is creating an initial array of all the possible questions, and an empty array of questions we're going to include on the quiz. We decide how many questions to include, in this example 5, and then loop that number of times.
On each iteration, we get the current length of the array holding all the possible questions, and pick a random number between 0 and the number of questions left in the array, then we push the question at that index value onto our array of quiz questions, and slice that question out of our array of possible questions so it's not there to get picked a second time.
Then we iterate again, now the source question array is one shorter, we get it's new length, pick a new random number and grab that question, add it to our quiz array, slice it out of our source questions array.
Lather, rinse, repeat.
QUESTION
I am trying to position a sprite at a point :
...ANSWER
Answered 2017-Jan-22 at 19:22The coordinate system of SpriteKit is cartesian, with an origin default of the middle of the screen, when using the starting template in Apple's Xcode.
This template sets the origin to the centre of the screen by using an origin setting of (0.5, 0.5)
To have a top left origin, you're going to need set this to (0, 1), and then invert Y values, to negative values.
