Connect Libre Office to Python

[Shantanu24]

Hey guys.
I am using the pyBarcode and dateandtime modules to generate a ean13 barcode that has the time and date as a string. All going well.
Now, I have 2 queries:
1. The last digit in the ean13 is changing randomly. I tried to simply add a number as a string to it as a last digit. But in vain. What may be the issue?

2. I want to now send this barcode to a Libre Office Word application for maintaining records. Is that at all possible using python?

I have a button interfaced. Everytime I press the button, a new barcode is generated. I want this to automatically be recorded into a libre office Writer. How would I go about it? Is it possible?

A1: you cannot meaningfully add a string to a number. You need to rethink the solution so you add two things of the same kind.

A2: does it have to be written to a file to be used by "Word"/LO_Writer? There are existing Python modules that can easily encode data into a .CSV file that you could then use as a spreadsheet.

The last digit is a Luhn check digit calculated from the first twelve digits.

Hello. It need not compulsorily be a file used by "Word/LO_Writer". I have managed to achieve loading data into a Spreadsheet/LO_Calc file. But I also need to add an image (.png) file. This .png file is the barcode image. I have managed to send the barcode string. But I also need to send the .png file. How is that possible?
