Thanks for writing @rongbing0353. A couple of things:

1. GEOS-Chem 13.0.0 is no longer supported. Please update to the latest version (14.5.0) when possible.
2. Try changing:

"""  prefix = ""
to
```python
"""
    prefix = ""

The problem is that the definition of prefix is on the same line as the """ comment header.
