Very good day, I would like to know if it is possible to make portable applications that is to say that they run on a USB and do not have to be installed on a computer, using python and a database to store data is redundant, and googled a lot and I can not find an answer. The idea is to make an app so that a teacher can keep the daily record of their students' contributions such as homework, exams, lessons, etc. Thank you very much ..
