# Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
To improve ergonomics of the API by providing a pre-initialized
`SessionContext` instance as `ctx`. This allows users to import and use a
context directly without initialization.
# What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
- Added `ctx = SessionContext()` in `__init__.py` to provide a default
context instance
- Added corresponding test `test_default_ctx_instance` to verify
functionality
- Included `ctx` in `__all__` for explicit exports
# Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->
Yes, users can now do:
```python
from datafusion import ctx # Get pre-initialized context
```
Instead of:
```
from datafusion import SessionContext
ctx = SessionContext() # Manual initialization
```
<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
It adds a new API for the users.
