How to provide additional information when raising exception
- How can I provide additional information when raising an exception?
# MWE- ```py
- filename = "bad_dir"
- print(f"File not found: {filename}.")
- raise(FileNotFoundError)
- ```
# QuestionHow do I raise an exception while adding additional information? In theexample above, the exception raised is printed at the bottom of thestacktrace, and the print above it is printed at runtime and hard tofind in the terminal.Is there a way to add a string to the raisedexception to provide additional information?
- Suppose I have some code like:

- filename = "bad_dir"
- print(f"File not found: {filename}.")
- raise(FileNotFoundError)
- ```
- When the exception isn't caught, the stack trace is printed at the end of the output, right as the program aborts. The `print`ed message could be far above this and is hard to find in the terminal and hard to associate with the exception.
- How can I provide additional information in the exception, so that it can be seen immediately when the traceback is displayed?
