-# raise-vanilla-class (TRY002)
-Derived from the **tryceratops** linter.
-
-### What it does
-Checks for bare exceptions.
-
-## Why is this bad?
-It's hard to capture generic exceptions making it hard for handling specific scenarios.
-
-## Example
-```py
-def main_function():
-    if not cond:
-        raise Exception()
-def consumer_func():
-    try:
-        do_step()
-         prepare()
-        main_function()
-    except Exception:
-        logger.error("I have no idea what went wrong!!")
-```
-
-## How it should be
-```py
-def main_function():
-    if not cond:
-        raise CustomException()
-def consumer_func():
-    try:
-        do_step()
-        prepare()
-        main_function()
-    except CustomException:
-        logger.error("Main function failed")
-    except Exception:
-        logger.error("I have no idea what went wrong!!")
-```
