Development of Python Student Information management system

# First: Design a global variable to hold a number of student information, students (student number, name, age), and how the structure of the thinking to be preserved;
# The second question: on the basis of the first question, complete: Let the user enter a new student information (school number, name, age); You save it in a global variable, and provide the user with the ability to see how many students are currently available;
# The third problem: to provide users with the number of students to view the specific information, specify student number to delete the student function

# used to save all the students ' information
