List slicing: • The process of choosing a range of data items from a list is called as list slicing. • In Python, an expression that chooses a sub list from a sequence is called as a slice. • A slice is a span of data items that are taken out from a list. • Generally, the slice expression has start and end indices as its inputs. • If the end index is not given, then the list’s length is taken as the end index. • The start and end indices in the list slice expression can also have the negative integers as their values. • The negative integers indicate the location that is relative to the end of the list. Syntax: In python, the list slice expression with a negative index has the below format. #Create an expression to slice the list listname[negative_index:] or #Create an expression to slice the list listname[:negative_index]

Program Plan Intro

List slicing:

• The process of choosing a range of data items from a list is called as list slicing.

• In Python, an expression that chooses a sub list from a sequence is called as a slice.

• A slice is a span of data items that are taken out from a list.

• Generally, the slice expression has start and end indices as its inputs.

• If the end index is not given, then the list’s length is taken as the end index.

• The start and end indices in the list slice expression can also have the negative integers as their values.

• The negative integers indicate the location that is relative to the end of the list.

Syntax:

In python, the list slice expression with a negative index has the below format.

#Create an expression to slice the list

listname[negative_index:]

or

#Create an expression to slice the list

listname[:negative_index]

Write a Java Program to manage student information of a university. The Javaprogram does the following steps:a) The program must use single-dimensional arrays to store the studentinformation such as Student ID, Name and Major.b) The program asks the user to provide the number of students.c) The program asks the user to enter the Student IDs for the number of studentsand stores them.d) The program asks the user to enter the corresponding names for the numberof students and stores them.e) The program then asks the user to provide the corresponding major for thestudents and stores them.f) The program then should display the following options:1. ID Search2. Major Enrollment3. Exitg) On selecting option 1, the user can search for a student using Student ID. Theprogram asks the user to enter a Student ID. It then should print thecorresponding student’s details such as Name and Major if the user providedStudent ID number is present in the stored data. If the user’s Student IDnumber does not…
