QUESTION
im trying to generate mastercard card number. requirements : first element must be 5 second element must be between 1 and 5 last element must be lcheck digit returned from luhn algorithm.
i have check digit function with luhn algorithm, so far everything is okay. but when i give parameter my card number to generateCheckDigit function in generateMasterCard function, my card number is returned as multiplied by 2, one element apart during the luhn algorithm.
sorry for my bad english
here is the codes:

Alexey Larionov sais in comments "In Python if you pass to a function some complicated value, like class instance, list, dictionary, etc, then your function can freely modify it. In your case, you do operation numbers[i] *= 2 and it changes the list you passed". Passing a copy allows you to avoid this.
QUESTION
I'm trying to write a version of Luhn's algorithm, but why is my code not doubling every odd index here? It seems to be doubling a pattern of index's but i dont understand how it's got that pattern from my code.
...ANSWER
Answered 2022-Jan-25 at 18:12If you are talking about odd indexes, the problem you use reversed[i] in the "for" loop, and later in the "if" condition. Replaced both instances by just "i". The "i" represents the index in this code.

QUESTION
This is a Luhn algorithm code and it works fine in an online complier but when I use it in my local vscode it is only giving 63 as output.
I dont know if its a memory issue as it late long variable.
i.e credit card number as input.
...ANSWER
Answered 2022-Jan-15 at 09:26The result depends on the size of the type long int that can be equal either to the size of the type int or to the size of the type long long int.
So use the type long long int instead of the type long int.
Also as the program expects an unsigned value then instead of the signed type long long int it is even better to use the type unsigned long long int.

QUESTION
I need to print all possible correct credit card numbers according to the Luhn algorithm, and I did like a 16 for loops nested inside each other, I was wondering if there is a way to make my code shorter? Here is my code:
this is for index 0,2,4,6,8,10,12,14,16 It takes the number and multiply it by 2. and after that it takes the sum of the individual numbers; lets say index 0 is 6 it takes 6*2=12 and sums 1+ 2
