## 🛠️ Description
-A simple converter app built in python.
+A simple converter app built in Python. Now supports both command-line and graphical user interface (GUI) modes with PyQt5 or Tkinter.
## ⚙️ Languages or Frameworks Used
-You only need Python to run this script. You can visit here to download Python.
+- Python 3
+- PyQt5 (for modern GUI)
+- Tkinter (for classic GUI)
## 🌟 How to run
-Running the script is really simple! Just open a terminal in the folder where your script is located and run the following command:
+Open a terminal in the folder where your script is located and run one of the following commands:
+**For the classic command-line converter:**
```sh
python converter.py
```
+**For the GUI version (choose PyQt5 or Tkinter):**
+```sh
+python converter_gui.py
+```
+You will be prompted to select which GUI you prefer (`pyqt5` or `tkinter`).
+
+- If you choose `pyqt5`, make sure you have PyQt5 installed:
+ ```sh
+ pip install pyqt5
+ ```
+- If you choose `tkinter`, it is included with most Python installations by default.

+# Password Generator
+
+This is a simple yet versatile password generator written in Python. It allows users to generate random passwords that include:
+
+- Special characters (`+`, `-`, `*`, `/`, `@`, `#`, etc.)
+- English letters (both lowercase and uppercase)
+- Greek letters (both lowercase and uppercase)
+
+The program provides two modes of use:
+- **Command-line interface (CLI)**
+- **Graphical User Interface (GUI) using Tkinter**
+
+## Features
+
+- User-defined password length.
+- Random character selection from multiple sets.
+- Supports both English and Greek letters.
+- Option to use a GUI or stay in the terminal.
+
+## How to Run
+
+### Requirements
+- Python 3.x
+- Tkinter (usually included with standard Python distributions)
+
+### Run the Program
+
+```bash
+python password\ generator.py
+```
+
+You will be asked whether you want to use the GUI:
+
+```
+Do you want to use the GUI version? (yes/no):
+```
+
+### If you choose `yes`:
+- A GUI window will appear.
+- Enter the desired password length.
+- Click "Generate Password" to create a new password.
+
+### If you choose `no`:
+- The program runs in the terminal.
+- You’ll be prompted to enter the desired length.
+- A password will be printed directly to the console.
+
+## Notes
+
+- The GUI version uses `tkinter.messagebox` for error handling.
+- The terminal version runs in a loop and generates a new password every time you provide a new length.
+- The output password may include Greek characters, so make sure your application or website supports Unicode characters if you're using these passwords.
+
+## Example Output
+
+```text
+Welcome to the Password Generator!
+This program generates a random password using special characters, English letters, and Greek letters.
+You can choose the length of the password, and it will include a mix of characters from these sets.
+Let's get started!
+Do you want to use the GUI version? (yes/no): no
+How many characters do you want your password to have? 12
+Your password is: αrΔh8@XωK$Π
+You can copy and save it somewhere
+I hope you liked my program!
