I am a beginner. II want to develop a GUI app for my school and enter the marks of students therein. I created a .db file containing the the register number, names and marks of students. The register number and names fields are pre-filled in the database (which I created from an excel sheet which is provided by the school). Now I want to enter the marks of each students in an Entry widget and update the all the marks in the database at once, with the click of a button..
