Certainly! Below is a simple Python script that prints "Hello, World!" to the console:
```python
print("Hello, World!")
```
To run this script, follow these steps:
1. Open a text editor and paste the above code into a new file.
2. Save the file with a `.py` extension, for example, `hello_world.py`.
3. Open a terminal or command prompt.
4. Navigate to the directory where you saved the file.
5. Run the script by typing `python hello_world.py` and pressing Enter.
You should see the output:
```
Hello, World!
```
This is one of the simplest ways to get started with Python programming. If you have any more questions or need further assistance, feel free to ask!

We need bold, immediate action—investing in renewable energy, creating green jobs, and holding polluters accountable. Our future depends on it. Let's lead the world in this fight!

Bob(Republican candidate): Alex, I understand the concern about our environment, but we must balance that with our need for a thriving economy. While I agree that we should pursue energy efficiency and cleaner energy sources, I believe that the free market, innovation, and American ingenuity are the keys to long-term sustainability. We need to support our energy sector as it transitions in a way that doesn't leave workers behind. My plan focuses on creating a healthy environment and a healthy economy – we can do both!

Bob, you're right about American ingenuity, but time is running out. We need a Green New Deal to rapidly transition to renewable energy, ensuring no worker is left behind with retraining programs and new job opportunities. This isn't just about the environment; it's about securing a prosperous future for all Americans. Let's act now before it's too late!

Bob (Republican candidate): Alex, I respect your passion, and I too recognize the importance of addressing climate change. But let's be clear: we can't afford to risk our economic stability with drastic measures that could lead to job loss and increased costs for American families. My approach is about pragmatism and practical solutions. We're going to harness the power of our energy industry by promoting research and development in new technologies, incentivizing cleaner practices, and supporting our workers through this transition. We need to be the world's leader in energy innovation, not just in setting ambitious goals. Let's focus on a strong, secure America that leads by example, not regulation!
