Python Projects: Student Grade Calculator, Palindrome Checker & Number Guessing Game

Are you ready to have some Python-powered fun? Well, you’re in for a treat! In this blog post, we’re diving into three awesome Python projects that not only entertain but also help you sharpen your programming skills.

  1. Palindrome Checker
  2. Student Grade Calculator
  3. Number Guessing Game

Whether you’re a student eager to calculate grades, a wordplay lover intrigued by palindromes, or just someone who enjoys a good challenge with number guessing, these projects cater to all tastes and skill levels.

In this friendly intro, I’ll give you a sneak peek into each project and explain why they’re perfect for boosting your Python prowess. So, get cozy, fire up your Python environment, and let’s embark on this coding adventure together!

  1. Palindrome Checker

The fundamental concept behind a palindrome checker involves comparing the original string with its reverse. If they match, the given word or phrase is a palindrome; otherwise, it is not. This comparison is achieved by reversing the characters of the string and then checking for equality.

To implement a palindrome checker in Python, we utilize the concept of lists to store the characters of the word or phrase. By reversing the list and comparing it with the original list, we can determine if the input is a palindrome or not. Below is a simple Python function to achieve this:

def is_palindrome(word):
word = word.lower() # Convert word to lowercase for case insensitivity
characters = list(word) # Convert word to list of characters
r_characters = characters[::-1] # Reverse the list
return characters == r_characters # Check for equality

The is_palindrome function first converts the input word to lowercase to ensure case insensitivity. It then converts the word to a list of characters using the list() function. The list is then reversed using slicing notation [::-1]. Finally, the function returns True if the original list matches the reversed list, indicating that the word is a palindrome.

2. Student Grade Calculator

Imagine you’re a teacher named MR. Tanmay, dedicated to nurturing young minds in your classroom. You have a diverse group of students, each with their own strengths and areas for growth. As you navigate through the academic year, you want to ensure each student receives the support they need to succeed.

  1. Input Scores: Let’s say you have students named Suraj, Jasmine, and Ekta. They’ve recently completed exams in Math, Science, and English. Suraj scored 85, 90, and 88 respectively; Jasmine scored 78, 82, and 80; and Ekta scored 92, 88, and 95.
  2. Store in Lists: You write down these scores on your reliable notepad,, creating lists for each subject. It’s like organizing pieces of a puzzle, ensuring nothing gets lost in the shuffle.
    • Math Scores: 85, 78, 92
    • Science Scores: 90, 82, 88
    • English Scores: 88, 80, 95
  3. Calculate Average: With the scores neatly arranged, you plug them into the Student Grade Calculator. It whirs to life, crunching numbers and churning out averages.
    • Suraj’s Average: (85 + 90 + 88) / 3 = 87.67
    • Jasmine’s Average: (78 + 82 + 80) / 3 = 80
    • Ekta’s Average: (92 + 88 + 95) / 3 = 91.67
  4. Feedback and Guidance: Armed with these averages, you sit down with each student to discuss their performance. You praise Suraj for his consistent effort and encourage her to keep up the good work. You offer support to Jasmine, noting areas where she can improve. And you commend Ekta for her outstanding results, challenging her to maintain her momentum.

Benefits of Using the Calculator

  • Efficiency: Instead of manually calculating averages, you can focus on providing personalized feedback and guidance to each student.
  • Accuracy: The Student Grade Calculator ensures precision in grading, minimizing the risk of errors or miscalculations.
  • Empowerment: By discussing their averages with students, you empower them to take ownership of their academic journey and set goals for improvement.

#Define the scores for each subject for three students

math_scores = [85, 78, 92]
science_scores = [90, 82, 88]
english_scores = [88, 80, 95]

#Function to calculate average grade

def cal_average(scores):
total = sum(scores)
return total / len(scores)

#Calculate average grades for each subject

avg_math = cal_average(math_scores)
avg_science = cal_average(science_scores)
avg_english = cal_average(english_scores)

#Print average grades for each subject

print(“Average Math Grade:”, avg_math)
print(“Average Science Grade:”, avg_science)
print(“Average English Grade:”, avg_english)

3. Number Guessing Game:

Picture yourself surrounded by friends on a chilly evening, seeking some good old-fashioned fun. The Number Guessing Game emerges like a burst of energy, infusing the air with giggles and eager anticipation. It’s more than just a game; it’s a shared adventure that strengthens bonds and tests your collective wit. With every guess, you draw closer together, united in laughter and friendly competition.

How it Works:

  1. Computer’s Choice: One of your friends volunteers to be the computer. They secretly select a number between a predetermined range, let’s say between 1 and 100. It’s like planting a hidden treasure, waiting to be discovered.
  2. Player’s Guess: Another friend, let’s call them the player, takes on the challenge of guessing the hidden number. They start by making their first guess, carefully considering their options and hoping for a stroke of luck.
  3. Track of Guesses: As the player makes their guesses, you jot down each guess on a piece of paper. It’s like keeping score in a thrilling game of chance, adding to the suspense with each attempt.
  4. Revealing the Answer: After each guess, the computer reveals whether the guess was too high, too low, or spot on. It’s like unraveling a mystery, inching closer to the elusive solution with each clue.
  5. Victory or Retry: The game continues until the player successfully guesses the hidden number or decides to call it quits. It’s like a rollercoaster ride of emotions, with each guess bringing the player closer to victory or prompting them to try again.

#Welcome message

print(“Welcome to the Number Guessing Game!”)

#Computer selects a random number between 1 and 100

import random
hidden_number = random.randint(1, 100)

#List to keep track of player’s guesses

guesses = [ ]

#Function to check if the guess is correct

def check_guess(guess, hidden_number):
if guess == hidden_number:
print(“Congratulations! You guessed the number correctly!”)
return True
elif guess < hidden_number:
print(“Too low! Try guessing higher.”)
return False
print(“Too high! Try guessing lower.”)
return False

#Game loop

while True:
# Player makes a guess
guess = int(input(“Enter your guess (between 1 and 100): “))

#Add Guess to the list of guesses


#Check if the guess is correct

if check_guess(guess, hidden_number):


#Display number of guesses made

print(“You made”, len(guesses), “guesses.”)

#Display all guesses made

print(“Your guesses:”, guesses)

In this code:

  • The game starts with a welcoming message.
  • The computer selects a random number between 1 and 100.
  • A list named guesses is initialized to keep track of the player’s guesses.
  • The check_guess() function compares the player’s guess with the hidden number and provides feedback.
  • Inside the game loop, the player makes guesses and the game continues until the correct number is guessed.
  • After the game ends, the total number of guesses made and all the guesses are displayed.

This code simulates the Number Guessing Game experience, where players interactively guess numbers until they find the correct one, adding a personal touch to the game.

4. Conclusion

In conclusion, these three Python projects offer a fantastic way to learn and have fun at the same time. From calculating grades to playing with words and numbers, each project provides a unique challenge that helps build your programming skills. So, whether you’re a beginner looking to dive into Python or an experienced coder seeking a creative outlet, these projects have something for everyone. Happy coding!
