PythonCall.jl how do I handle Python exceptions?

Using [PythonCall.jl](https://github.com/JuliaPy/PythonCall.jl), how do I best handle python exception patters such as the following python:

```
try:
database = client.create_database(DATABASE_NAME)
except exceptions.CosmosResourceExistsError:
database = client.get_database_client(DATABASE_NAME)
```

[xref stackoverflow](https://stackoverflow.com/questions/77333648/julia-pythoncall-jl-how-do-i-handle-python-exceptions)

The issue points to PythonCall.jl and a linked Stack Overflow question; start by reviewing PythonCall.jl's exception-handling API and the referenced Python example. Document how to catch the specified Python exception and perform the fallback, with a clear usage example as the completion criterion.
