Python Interactive: Exception won't print message inside angle brackets

Raising an exception in the Python Interactive Window with a message that contains angle brackets <> will remove the text within the angle brackets (and the brackets themselves) from the message, provided the text begins with an alphabetic character. This doesn’t happen with print statements or if the text inside the brackets begins with a non-alphabetic character. If no closing bracket exists in the message, the rest of the message will be removed.

Environment data

• VS Code version: 1.37.1

Expected behaviour

The entire message should be printed when an Exception is raised.

Actual behaviour

The text within the angle brackets is removed.

Steps to reproduce:

1. Open a Python Interactive window and run the command raise Exception("abc<def>ghi")

@oliverhiggs. Thanks for the report and the detailed repro. I can confirm what you are seeing, and that it does display correctly in Jupyter. We’ll look into it.
