In this project, you’ll develop a Student Grades Analyzer in Python that can:

Store student names and their grades
Calculate averages
Identify top and lowest performers
Display useful statistics

This project helps you strengthen your skills with lists, dictionaries, loops, and data analysis logic.

🧠 Key Concepts Covered

Concept	Description
Lists & Dictionaries	Store student names and grades efficiently.
Loops	Iterate through data for calculations.
Conditionals	Compare grades and find top performers.
Data Analysis	Compute average, max, and min values.

🧰 What You’ll Need

Python 3 installed
Basic knowledge of loops, lists, and dictionaries
(Optional) Familiarity with CSV files for data import/export

💻 Step-by-Step Code

File Name: grades_analyzer.py

# 🎓 Student Grades Analyzer

def add_student(students):
    name = input("Enter student name: ")
    grades = input("Enter grades separated by commas: ")
    grade_list = [float(g.strip()) for g in grades.split(",")]
    students[name] = grade_list
    print(f"✅ {name} added successfully!\n")

def calculate_average(grades):
    return sum(grades) / len(grades)

def show_statistics(students):
    print("\n📊 Class Statistics:\n")
    averages = {name: calculate_average(grades) for name, grades in students.items()}

    for name, avg in averages.items():
        print(f"{name}: {avg:.2f}")

    top_student = max(averages, key=averages.get)
    lowest_student = min(averages, key=averages.get)
    class_average = sum(averages.values()) / len(averages)

    print("\n🏅 Top Student:", top_student, f"({averages[top_student]:.2f})")
    print("📉 Lowest Student:", lowest_student, f"({averages[lowest_student]:.2f})")
    print(f"📘 Class Average: {class_average:.2f}\n")

def main():
    students = {}

    while True:
        print("🎓 Student Grades Analyzer")
        print("1. Add Student")
        print("2. View Statistics")
        print("3. Exit")

        choice = input("Choose an option (1-3): ")

        if choice == "1":
            add_student(students)
        elif choice == "2":
            if students:
                show_statistics(students)
            else:
                print("⚠️ No students added yet.\n")
        elif choice == "3":
            print("👋 Goodbye!")
            break
        else:
            print("❌ Invalid choice. Try again.\n")

if __name__ == "__main__":
    main()

🧩 Example Output

🎓 Student Grades Analyzer
1. Add Student
2. View Statistics
3. Exit
Choose an option (1-3): 1
Enter student name: Alice
Enter grades separated by commas: 90, 85, 88
✅ Alice added successfully!

🎓 Student Grades Analyzer
1. Add Student
2. View Statistics
3. Exit
Choose an option (1-3): 2

📊 Class Statistics:
Alice: 87.67

🏅 Top Student: Alice (87.67)
📉 Lowest Student: Alice (87.67)
📘 Class Average: 87.67

🚀 Bonus Improvements

Save and load student data from a CSV file using the csv module.
Add grading categories (tests, homework, projects).
Use Matplotlib to visualize grade distributions.
Create a GUI version using tkinter.

🧠 Summary

You built a Student Grades Analyzer that stores data dynamically.
You used loops, lists, and dictionaries to process and analyze information.
You learned how to calculate averages and generate performance insights.
