Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

A file marks.txt holds Asha:72, Ravi:85, Meera:64, one on each line. Write a function set_mark(name, mark) that changes the mark of a name in the file, or adds the name if it is not there, and keeps all the other lines. Test it with ("Ravi", 90) and ("Kabir", 50).
