creditcards | Parse , format , and validate credit cards in JS | Ecommerce library

I have a credit card number input and I am trying to add an image of the credit card brand next to the text field based on the number the user entered. whether that may be visa, master card, etc.

I have created a struct for the credit cards:

I am cathing one API and I cannot deserialize a JSON property and I do not know where is the problem.

So I have an object from convertJSON2CSharp :

I can't create the superuser when I create this model in my app.
WHen I remove AUTH_USER_MODEL = 'app.User' from my settings then showing another error "django.core.exceptions.FieldError: Unknown field(s) (full_name) specified for User" but I can create superuser on that time. Even I tried to fill up every single field with "null=True" and solved the error but can't log in to my admin panel with the created email password. I can't understand exactly where was the problem.
.

Here is my all code.

I am developing credit card fraud detections project in machine learning. I have download the code form GitHub (https://github.com/devrajkataria/Credit-Card-Fraud-Detection-ML-WebApp) but I am getting following errors:

For the below simplified transformation sheet, I'd like to add the following functions:

1. For "Turnover 2019" and "Turnover 2020" I'd like to get the values below 1mio in a red badge and over 1mio in a green badge. I tried to implement this for "Turnover 2019", however I just get a blank output. The problem seems to be with the -part, as I do get the correct value if I just enter (see "Turnover 2020").
2. For "Total Turnover" I need to sum up the values of "Turnover 2019" and "Turnover 2020". How do I do that?

XSL:

This is my first post on here so please tell me if i made any mistakes. I tried to find an answer to my question on here but i couldn't find anything fitting.

so i have a problem in my code for the 'Credit' problem set of CS50x's week 1. In the problemset the user has to enter a creditcard number that we have to verify as either VISA, MASTERCARD or AMEX. Otherwise the output should be INVALID.

The verification should work like this:

4 0 0 3 6 0 0 0 0 0 0 0 0 0 1 4

every second digit, starting from the second to last digit (the bold ones), is multiplied by 2 and added together. If however the multiplied digit has 2 digits, those two digits are added seperatly like:

2 * 6 = 12 so twelve will be 1 + 2

after that you take the other half of the digits (without multiplying them) and add them together so in the end you have something like

8 + 0 + 1 + 2 + 0 + 0 + 0 + 0 + 2 = 13 (for the digits displayed in bold)

and

0 + 3 + 0 + 0 + 0 + 0 + 0 + 4 = 7 (for the other half of the digits)

You add both together to get 20 (which in the problem set is called the checksum. If the last digit of the calculated number is a 0 the card is valid and after that you just have to check some conditions to tell if its an AMEX, VISA or MASTERCARD.

Conditions for the different creditcards:

American Express = 15 Digits, starting with 34 or 37

VISA = 13 or 16 Digits, starting with 4

MasterCard = 16 Digits, starting with 51, 52, 53, 54 or 55

(Sorry for the long introduction)

I tried to make a formular for this calculation but for some reason it doesn't work for all of the numbers we get to test it. I tried a lot of things to change the calculation and the conditions at the end of my code but everytime i fix one problem, another one appears and right now it feels like i thought myself into a rabbit hole so maybe i'm just too blind to see the obvious.

We only use the libraries - - so far.

I have a big sporadic sql scripts and need to find and replace a few values in it. I am trying to pass my values in REGEX to Notepad++ but I can't seem to make it work. To be more specific, I have around 50 script, each with 5000 lines, and I need to look for a list of values, e.g. "[dbo].[livesales]" "[dbo].[CreditCards]" in all my scripts separately. I undertand that I need either run this separately against each script or merger them all into one file, but I need the proper REGEX command for it. I need to include square bracket and dots as well. I end up building this but it doesn't work for me:

I am trying to save some customer details to a customer record. I have created this method but it fails when I get to putting in the expire date.

Your program is required to search through the three files to find a credit card number used at all three stores. Then output what that number is.

You may follow the rough pseudo code below. Note that it is incomplete and that you may be required to interpret missing parts. Properly document and comment your code.

Main Method: Process First Store declare and initialize a Boolean variable match to false read a credit card number from the file while match is false, and the credit card number is not null pass the credit card number to the method that processes the second store. If it returns true set match to true, otherwise repeat from (2) if match is true or the credit card number is null then finish the program. Depending on the value of match, output the matching result or indicate no match found.

This is the question , I have written the code but the problem is its comparing one line by another line in the other text file , not taking only one value then comparing it with whole values in another file. Please Help , a small idea would also be appreciated . Please help me in the concept!
