Sure! Here’s a quick guide to installing Python on Windows 11:

### Step 1: Download Python
1. Go to the official Python website: [python.org](https://www.python.org/downloads/)
2. Click the "Download Python" button. This will download the latest version of Python.

### Step 2: Run the Installer
1. Locate the downloaded file (usually in your Downloads folder) and double-click the installer.
2. Make sure to check the box that says "Add Python to PATH". This ensures that Python can be run from the command line.
3. Click "Install Now".

### Step 3: Verify the Installation
1. Open Command Prompt. You can do this by pressing `Win + R`, typing `cmd`, and pressing Enter.
2. Type `python --version` and press Enter. You should see the version of Python you installed.
3. Type `pip --version` and press Enter to check that pip (Python's package installer) is also installed.

### Step 4: Install a Code Editor (Optional)
1. Download and install a code editor like Visual Studio Code from [code.visualstudio.com](https://code.visualstudio.com/).
2. Once installed, you can open VS Code and use it to write and run Python code.

That's it! Python should now be installed on your Windows 11 machine.

 

第二步:

The error indicates that the Python Imaging Library (PIL), which is used for image processing, is not installed in your Python environment. PIL has been succeeded by a library called Pillow, which is a more up-to-date and actively maintained version.

Here's how you can install Pillow:

1. **Open Command Prompt**:
- Press `Win + R`, type `cmd`, and press Enter.

2. **Install Pillow using pip**:
- In the Command Prompt, type the following command and press Enter:
```
pip install Pillow
```

3. **Verify Installation**:
- After installation, you can verify it by trying to import Pillow in a Python shell. Open Python by typing `python` in the Command Prompt and pressing Enter, then type:
```python
from PIL import Image, UnidentifiedImageError
```
- If there are no errors, Pillow is installed correctly.

4. **Run Your Script Again**:
- Now, try running your script again to see if the error is resolved.

### Additional Notes
- Ensure that you are using the same Python environment where you installed Pillow. If you are using a virtual environment, make sure it is activated when you install Pillow and when you run your script.

If you encounter any issues during the installation, please let me know!
