How to install and configure Python?

To install and configure Python, follow these steps:

Installation

Download Python:

Go to the official Python website (python.org).
Navigate to the "Downloads" section.
Download the latest stable version suitable for your operating system (Windows, macOS, Linux).

Install Python:

Windows: Run the installer and check the box that says "Add Python to PATH" before finishing the installation.
macOS: Use the installer package and follow the on-screen instructions.
Linux: Use a package manager like apt (Debian/Ubuntu) or yum (CentOS/RHEL). For example, on Debian/Ubuntu, you can install Python using:
```
sudo apt update
sudo apt install python3
```

Configuration

Verify Installation:

Open a terminal or command prompt.
Type python --version or python3 --version to check if Python is installed correctly and note the version number.

Set Up Virtual Environment (Optional but Recommended):

Install virtualenv using pip:
```
pip install virtualenv
```
Create a new virtual environment:
```
virtualenv myenv
```
Activate the virtual environment:
- Windows:
```
myenv\Scripts\activate
```
- macOS/Linux:
```
source myenv/bin/activate
```

Install Packages:

With the virtual environment activated, you can now install Python packages using pip. For example:
```
pip install requests
```

Example Usage

Create a simple Python script to ensure everything is working:

# hello.py
print("Hello, World!")

Run the script:

python hello.py

You should see the output:

Hello, World!
