Question

Write a program that accepts the name of a group of 5 students and their age one by one. The program will then calculate the average of their ages and will print the result. The program will also print the name and age of the oldest person in the list.​

Answer 1

Hey there! I remember based off the last one we needed a beginner friendly version rather than a advanced version! So with that in mind...

names = [None] * 5

ages = [0] * 5

# Collect the names and ages of the 5 students

for i in range(5):

name = input("Please enter the name of student " + str(i + 1) + ": ")

age = int(input("Please enter the age of student " + str(i + 1) + ": "))

names[i] = name

ages[i] = age

# Calculate the average age

average_age = sum(ages) / len(ages)

# Find the oldest student

oldest_age = max(ages)

oldest_index = ages.index(oldest_age)

oldest_name = names[oldest_index]

# Print the results

print("The average age is:", average_age)

print("The oldest student is " + oldest_name + " with an age of " + str(oldest_age))

Step-by-step explanation:

We create two lists, names and ages, with 5 elements each. The names list is initialized with None values, and the ages list is initialized with 0 values.

Then, we use a for loop to iterate 5 times, as we want to collect information about 5 students. In each iteration, we ask the user to input the name and age of a student.

We use the input() function to get the name of the student and directly assign it to the corresponding index in the names list using names[i] = name.

We use the int() function to convert the user input into an integer (since age is a whole number) and directly assign it to the corresponding index in the ages list using ages[i] = age.

After collecting all the information, we calculate the average age by summing up all the ages in the ages list using the sum() function and dividing it by the number of students (in this case, 5).

To find the oldest student, we first determine the highest age using the max() function, which returns the maximum value in the ages list. Then, we use the index() method to find the index of the oldest age in the ages list. With this index, we can find the corresponding name of the oldest student in the names list.

Finally, we print the average age and the name and age of the oldest student using the print() function.

NOTE: The main difference in this version of the code is that we initialize the lists with a fixed size and assign values directly to each index instead of using the append() method to add elements to the lists.

Answer 2

Here's a Python program that accepts the name and age of five students, calculates the average of their ages, and prints the name and age of the oldest student:

# initialize variables

names = []

ages = []

max_age = 0

max_name = ""

# loop to get names and ages

for i in range(5):

name = input("Enter student name: ")

age = int(input("Enter student age: "))

names.append(name)

ages.append(age)

if age > max_age:

max_age = age

max_name = name

# calculate average age

avg_age = sum(ages) / len(ages)

# print results

print("Average age: ", avg_age)

print("Oldest student: ", max_name, max_age)

This program uses a list to store the names and ages of the students. It also keeps track of the maximum age and the corresponding name as it iterates through the input loop. Finally, it calculates the average age and prints out the results.
