- Simple Student Management System Build the following app using Python Tkinter library. Using this app, user can • add student information • view all students • search student(s) by name • remove student by id Add • First name, last name, date of birth cannot be blank while adding a specific student information. • However major can be blank, which gets set to "Undefined" if left out blank. • Student Id is automatically generated by the program (ex: 1001, 1002, 1003, 1004 ….) If the user keeps a mandatory field blank (ex: First name) and presses "Add Student" button, it displays the following message box: first name is required If the user successfully enters all the necessary information and presses the "Add Student" button, it displays the following confirmation message box: student added View All When the user presses the "View All" button, it displays all the student’s information (Id, First name, Last name, Date of birth, and Major) in a nice formatted way.

For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work. The flowchart must include a call symbol, at the beginning, to redirect the input to the external data file. create a solution algorithm using pseudocode create a flowchart using RAPTOR
