3.5 code practice input a grade number (9-12) and print Freshman, Sophomore, junior, senior

3.5 code practice input a grade number (9-12) and print Freshman, Sophomore, junior, senior. if it is not in [9-12] , print not in highschool.

The correct answer and explanation is:

Here’s the correct Python code for the problem:

grade = int(input("Enter your grade (9-12): "))

if grade == 9:
    print("Freshman")
elif grade == 10:
    print("Sophomore")
elif grade == 11:
    print("Junior")
elif grade == 12:
    print("Senior")
else:
    print("Not in high school")

🔍 Explanation (Approx. 300 words)

This simple Python program takes a grade level input from the user and prints the corresponding high school classification. The recognized grade levels in U.S. high schools are typically grades 9 through 12, and each corresponds to a specific title:

• 9th grade = Freshman
• 10th grade = Sophomore
• 11th grade = Junior
• 12th grade = Senior

✅ How the Code Works:

1. Input Collection: grade = int(input("Enter your grade (9-12): ")) This line asks the user to enter a number representing their grade. The input() function reads the input as a string, and int() converts it to an integer for comparison.
2. Conditional Logic:
   The program uses a series of if, elif, and else statements to determine which title to print based on the value of grade:
   • If grade == 9, it prints "Freshman".
   • If grade == 10, it prints "Sophomore".
   • If grade == 11, it prints "Junior".
   • If grade == 12, it prints "Senior".
   • If none of these conditions match (i.e., the number is not 9, 10, 11, or 12), the else block runs, printing "Not in high school".

🧠 Why It’s Important:

This practice helps students understand how conditional statements (if, elif, else) work in Python. It also shows the importance of data validation, since any number outside the 9–12 range is caught by the else statement.

This type of logic is commonly used in real-world programs to map numeric input to specific categories or responses.
