It seems like there might be an issue with how the code is being copied or interpreted in IDLE Shell. Let's go through a few possible reasons and solutions:
### **Possible Causes**
1. **Syntax Error Due to Incomplete Assignment**
- If `b =` is written without a value, Python will throw a `SyntaxError`.
- Ensure that `b` is assigned a valid value, like an empty list `[]`.
2. **Copy-Paste Issues**
- Sometimes, copying from certain sources (like formatted text or PDFs) can introduce invisible characters that cause syntax errors.
- Try manually typing the code instead of copying and pasting.
3. **IDLE Shell Behavior**
- If you are running the code **line by line** in IDLE Shell, an incomplete statement like `b =` will immediately cause an error.
- Ensure you are running the entire block of code at once.
4. **Python Version Issues**
- Ensure you are using a compatible Python version (`python --version` in terminal/command prompt).
- If using an older version, try updating Python.
### **Corrected Code**
Try running this in IDLE Shell **as a whole block**:
- import random
- i = 0
- b = [] # Correctly initializing b as an empty list
- while i < 10:
- b.append(random.randint(1, 35))
- i += 1
- print(b)
复制代码
### **Steps to Fix**
1. **Restart IDLE** and try again.
2. **Manually type the code** instead of copying and pasting.
3. **Run the script as a `.py` file** instead of executing it in the interactive shell.
4. **Check for hidden characters** by retyping the `b = []` line.
If the issue persists, let me know what exact Python version you are using (`python --version`).
