+# Calculator Program
+
+## Overview
+
+This is a simple calculator program written in Python. It supports basic arithmetic operations including Addition, Subtraction, Multiplication, and Division. The user can interact with the program through a command-line interface to perform calculations.
+
+## Features
+
+- **Addition (`+`)**: Adds two numbers.
+- **Subtraction (`-`)**: Subtracts the second number from the first number.
+- **Multiplication (`*`)**: Multiplies two numbers.
+- **Division (`/`)**: Divides the first number by the second number. If the second number is zero, it returns an error message.
+- **Quit (`quit`)**: Ends the program.
+
+## How to Use
+
+1. Run the script to start the calculator.
+2. The program will display a list of options for the available operations.
+3. Enter the operator for the desired operation.
+4. Enter two numbers separated by a space when prompted.
+5. The result of the operation will be displayed.
+6. To exit the program, enter `quit` when asked for the operator.
+
+## Example
+```
+Options:
+Enter '+' to add
+Enter '-' to subtract
+Enter '*' to multiply
+Enter '/' to divide
+Enter 'quit' to end the program
+Enter your operator: +
+Enter two numbers separated by space: 5 3
+Result: 5.0 + 3.0 = 8.0
+```
+
+## Error Handling
+The calculator program includes basic error handling to manage common errors:
+
+1. **Division by Zero:**
+
+- If the user attempts to divide by zero, the program will return the following error message: 
+```
+Enter your operator: /
+Enter two numbers separated by space: 10 0
+Result: 10.0 / 0.0 = Error: Division by zero is not allowed
+```
+2. **Invalid Numerical Input**
+
+- If the user enters non-numerical values or an incorrect format for the numbers, the program will catch a ValueError and display the following message:
+```
+Enter your operator: +
+Enter two numbers separated by space: 10 a
+Invalid Input: Please enter two numerical values separated by space.
+```
+3. **Invalid Operator:**
+
+- If the user enters an operator that is not supported, the program will display the following message: 
+```
+Enter your operator: %
+Invalid Input: Please enter a valid operator
+```

+# Random Number Guessing Game
+
+## Overview
+
+This is a simple Python program where the user tries to guess a random number chosen by the computer. The number is between 1 and 100, and the user has a limited number of attempts to guess it correctly.
+
+## Features
+
+- **Random Number Generation**: The program generates a random number between 1 and 100 at the start of each game.
+- **User Input**: The user is prompted to enter their guess.
+- **Feedback**: The program provides feedback if the guess is too high or too low.
+- **Limited Attempts**: The user has up to 4 attempts to guess the number correctly.
+- **Victory and Loss Messages**: The program displays a congratulatory message if the user guesses correctly, and a message with the correct number if the user runs out of attempts.
+
+## How to Use
+
+1. **Run the Program**: Execute the script to start the game.
+2. **Start Guessing**: Follow the on-screen instructions to enter your guesses.
+3. **Receive Feedback**: After each guess, the program will tell you if your guess is too high, too low, or correct.
+4. **Win or Lose**: The game ends either when you guess the number correctly or when you run out of attempts.
+
+## Example Usage
+
+```
+The computer has chosen a number!
+ARE YOU READY TO GUESS THE NUMBER!!
+Let's start the game
+Choose a number between 1 and 100
+NOTE: You will have 4 attempts to guess the number
+Enter your guess: 50
+The value you guessed is less than the computer generated number. You have used 1 out of 4 attempts. Try again!
+Enter your guess: 75
+The value you guessed is greater than the computer generated number. You have used 2 out of 4 attempts. Try again!
+Enter your guess: 60
+The value you guessed is less than the computer generated number. You have used 3 out of 4 attempts. Try again!
+Enter your guess: 70
+Congratulations! You guessed the number correctly!
+You took 4 attempts
+```
+## Error Handling
+
+The program includes basic error handling to manage common input errors:
+
+1. **Invalid Input**:
+    - If the user enters a non-numeric value, the program will display the message: `Invalid Input: Please enter a valid number.`
+    - The attempt will not be counted in case of an invalid input.
+
+2. **Out of Attempts**:
+    - If the user does not guess the number correctly within the allowed attempts, the program will display the correct number and end the game.
