Encoder-Decoder in Python

This simple Python program encodes and decodes strings into binary representation and back. It takes a string as input, converts each character into its binary equivalent, and allows you to decode a list of binary values back into a string.

Features

• Encoding: Converts each character of a string into its binary representation (Unicode code point).
• Decoding: Converts a list of binary strings back into the original string.

How It Works

1. Encoding:

   • The program takes a string input from the user.
   • It converts each character into its Unicode code point (integer) and then into a binary string.
   • The binary representation is printed as a list of binary values.

2. Decoding:

   • The program prompts the user to enter a space-separated list of binary values.
   • It then converts each binary value back into the corresponding character and prints the decoded string.

Example Usage

Encoding:

Enter Name: Alice Encoded (binary representation): ['1000001', '1101100', '1100101', '1100010', '1100100']

Decoding:

Enter the space-separated list of binary values: 1000001 1101100 1100101 1100010 1100100 Decoded (characters): ['A', 'l', 'i', 'c', 'e']

Code Walkthrough

Encoder

• Input: A string (e.g., "Alice").
• Process: Each character is converted to its Unicode code point using ord() and then to a binary string using bin().
• Output: A list of binary strings representing the encoded characters.

Decoder

• Input: A list of binary values (space-separated).
• Process: Each binary string is converted back into its integer value using int(binary_value, 2) and then back to a character using chr().
• Output: A list of characters decoded from the binary strings.

Requirements

This program only requires Python 3.x. No external libraries are needed.

Running the Program

1. Clone this repository or copy the code into a Python file (e.g., encoder_decoder.py).
2. Run the program using Python:
