Intro notebook raises `_IncompleteInputError` when running sequentially

[sahithiroy]

Hi,

While running python/intro/intro.ipynb in VS Code using "Run All", I encountered an _IncompleteInputError for the following cell:

cbioportal.Cancer_Types.getAllCancerTypesUsingGET(

Since the parentheses are not closed, executing the cell directly raises an error.

It appears this cell is intended only to demonstrate parameter inspection (e.g., using Shift+Tab), but when running the notebook sequentially, it causes confusion for users.

Suggested Improvement

To improve usability, one of the following could help:

Add a comment explaining that the cell is not meant to be executed

Complete the function call so the notebook runs without errors

Convert the snippet into a Markdown example instead of executable code

I’d be happy to submit a PR with a proposed fix.

Thanks!
