Write a program to input names of n students and store them in a tuple. Also, input a name from the user and find if this student is present in the tuple or not. We can accomplish these by: (a) writing a user defined function (b) using the built-in function

Write a program to input names of $n$ students and store them in a tuple. Also, input a name from the user and find if this student is present in the tuple or not.

We can accomplish these by:

(a) writing a user defined function

(b) using the built-in function

Below is a Python program that performs the required tasks. Both approaches (using a user-defined function and using a built-in function) are provided.

Using a User-Defined Function

def check_student_in_tuple(students_tuple, student_name):
    """Function to check if a student is in the tuple."""
    return student_name in students_tuple

# Input the number of students
n = int(input("Enter the number of students: "))
students = []

# Input the names of the students
for i in range(n):
    name = input("Enter the name of student {}: ".format(i+1))
    students.append(name)

# Convert the list to a tuple
students_tuple = tuple(students)

# Input the name to be searched
search_name = input("Enter the name you want to search: ")

# Check if the student is present
if check_student_in_tuple(students_tuple, search_name):
    print(f"{search_name} is present in the tuple.")
else:
    print(f"{search_name} is not present in the tuple.")

Using Built-in Function

# Input the number of students
n = int(input("Enter the number of students: "))
students = []

# Input the names of the students
for i in range(n):
    name = input("Enter the name of student {}: ".format(i+1))
    students.append(name)

# Convert the list to a tuple
students_tuple = tuple(students)

# Input the name to be searched
search_name = input("Enter the name you want to search: ")

# Check if the student is present using the 'in' operator
if search_name in students_tuple:
    print(f"{search_name} is present in the tuple.")
else:
    print(f"{search_name} is not present in the tuple.")

Both methods will:

1. Ask for the number of students.

2. Collect the names of the students and store them in a tuple.

3. Take a name input from the user and check if the name exists in the tuple.

4. Print whether the name is found in the tuple or not.

In the first method, a user-defined function check_student_in_tuple is used to check the presence of the student's name. In the second method, the in-built in operator is directly utilized to perform the check.
