Leitner system is a method to help memorizing efficiently. Every time I looked on the web for a package to do the job, I could not find the right version. At the end I concluded none of the authors have understood the Leitner system right. I made my Leitner system in Python to help learning Spanish language. But this Leitner System can be used for anything!
To start just create your own courseraw.txt and start putting your data in the text. See an example file below:
¡Hola!
Hello!
¡Adios!
Bye!
