Project 1: To-Do List Application:
Step 1: Initialize an Empty List
We’ll start by initializing an empty list to store the tasks entered by the user.
tasks = []Step 2: Add Tasks to the List
Allow users to add tasks to the to-do list using the append() method.
def add_task(task):
tasks.append(task)
print("Task added successfully!")
Step 3: Remove Tasks from the List
Enable users to remove tasks from the list by specifying the task index.
def remove_task(index):
if 0 <= index < len(tasks):
removed_task = tasks.pop(index)
print(f"Task '{removed_task}' removed successfully!")
else:
print("Invalid task index!")
Step 4: Mark Tasks as Completed
Implement functionality to mark tasks as completed by updating their status.
def mark_completed(index):
if 0 <= index < len(tasks):
tasks[index] += " (Completed)"
print("Task marked as completed!")
else:
print("Invalid task index!")
Step 5: Main Function for User Interaction
Create a main function to interact with users and perform operations based on their inputs.
def main():
while True:
print("\nMenu:")
print("1. Add Task")
print("2. Remove Task")
print("3. Mark Task as Completed")
print("4. Exit")
choice = input("Enter your choice: ")
if choice == "1":
task = input("Enter task: ")
add_task(task)
elif choice == "2":
index = int(input("Enter index of task to remove: "))
remove_task(index)
elif choice == "3":
index = int(input("Enter index of task to mark as completed: "))
mark_completed(index)
elif choice == "4":
print("Exiting program...")
break
else:
print("Invalid choice!")

Project 2: Tic-Tac-Toe Game:
Step 1: Set Up the Game Board
Define the game board as a 3×3 grid represented by a list of lists. Initialize the board with empty spaces.
# Initialize the game board
board = [[' ' for _ in range(3)] for _ in range(3)]
Step 2: Display the Game Board
Create a function to display the current state of the game board.
def display_board():
for row in board:
print('|'.join(row))
print('-' * 5)
Step 3: Get Player Input
Define a function to get player input for their moves and update the game board accordingly.
def get_move(player):
while True:
try:
row = int(input(f"Player {player}, enter row (0, 1, 2): "))
col = int(input(f"Player {player}, enter column (0, 1, 2): "))
if 0 <= row <= 2 and 0 <= col <= 2 and board[row][col] == ' ':
return row, col
else:
print("Invalid move. Try again.")
except ValueError:
print("Invalid input. Please enter a number.")
Step 4: Check for Winning Condition
Define a function to check for the winning condition after each move.
def check_win(player):
for row in board:
if all(cell == player for cell in row):
return True
for col in range(3):
if all(board[row][col] == player for row in range(3)):
return True
if all(board[i][i] == player for i in range(3)) or all(board[i][2 - i] == player for i in range(3)):
return True
return False
Step 5: Main Game Loop
Create the main game loop where players take turns making moves until a winner is determined or the game ends in a draw.
def main():
player = 'X'
while True:
display_board()
row, col = get_move(player)
board[row][col] = player
if check_win(player):
display_board()
print(f"Player {player} wins!")
break
if all(board[i][j] != ' ' for i in range(3) for j in range(3)):
display_board()
print("It's a draw!")
break
player = 'O' if player == 'X' else 'X'
if __name__ == "__main__":
main()
Final Code:
# Initialize the game board
board = [[' ' for _ in range(3)] for _ in range(3)]
def display_board():
for row in board:
print('|'.join(row))
print('-' * 5)
def get_move(player):
while True:
try:
row = int(input(f"Player {player}, enter row (0, 1, 2): "))
col = int(input(f"Player {player}, enter column (0, 1, 2): "))
if 0 <= row <= 2 and 0 <= col <= 2 and board[row][col] == ' ':
return row, col

Project 3: Guess the Number Game:
Step 1: Generate a Random Number
We’ll use the random module to generate a random number within a specified range.
import random
# Generate a random number between 1 and 100
secret_number = random.randint(1, 100)
Step 2: Get User Input
Prompt the user to enter their guess and convert the input to an integer.
guess = int(input("Enter your guess (between 1 and 100): "))
Step 3: Compare Guess with the Secret Number
Check if the user’s guess matches the secret number and provide appropriate feedback.
if guess == secret_number:
print("Congratulations! You've guessed the correct number.")
elif guess < secret_number:
print("Too low! Try guessing a higher number.")
else:
print("Too high! Try guessing a lower number.")
Step 4: Repeat Until Correct Guess
Utilize a loop to allow the user to keep guessing until they guess the correct number.
while guess != secret_number:
guess = int(input("Try again. Enter your guess: "))
if guess == secret_number:
print("Congratulations! You've guessed the correct number.")
elif guess < secret_number:
print("Too low! Try guessing a higher number.")
else:
print("Too high! Try guessing a lower number.")
Final Code:
import random
# Generate a random number between 1 and 100
secret_number = random.randint(1, 100)
print("Welcome to the Guess the Number Game!")
print("I've selected a number between 1 and 100. Try to guess it.")
# Get initial guess from the user
guess = int(input("Enter your guess (between 1 and 100): "))
# Check if the guess is correct and provide feedback
while guess != secret_number:
if guess < secret_number:
print("Too low! Try guessing a higher number.")
else:
print("Too high! Try guessing a lower number.")
guess = int(input("Try again. Enter your guess: "))
# Display congratulatory message for correct guess
print("Congratulations! You've guessed the correct number.")
