Hey - I've found 2 issues, and left some high level feedback:
- In
decorator_arguments.py, thewrappercurrently only accepts a single positional argumentx; if you intend this decorator to be reusable, consider changing the signature towrapper(*args, **kwargs)and extracting the value to check, so it works with functions that take multiple or keyword arguments while preserving call semantics. - The error handling in
decorator_arguments.pyusese.message, which is not a standard attribute onValueErrorin modern Python; usestr(e)(orrepr(e)) in the f-string instead to ensure the exception message is printed correctly. - The new README entry under
source-code/decorators/README.mdrefers to acheck_rangedecorator, but the implementation is namedcheck_bounds; aligning the names will avoid confusion for readers looking for the example.

## Overall Comments
- In `decorator_arguments.py`, the `wrapper` currently only accepts a single positional argument `x`; if you intend this decorator to be reusable, consider changing the signature to `wrapper(*args, **kwargs)` and extracting the value to check, so it works with functions that take multiple or keyword arguments while preserving call semantics.
- The error handling in `decorator_arguments.py` uses `e.message`, which is not a standard attribute on `ValueError` in modern Python; use `str(e)` (or `repr(e)`) in the f-string instead to ensure the exception message is printed correctly.
- The new README entry under `source-code/decorators/README.md` refers to a `check_range` decorator, but the implementation is named `check_bounds`; aligning the names will avoid confusion for readers looking for the example.

**suggestion:** Decorator only supports a single positional argument; consider generalizing to *args/**kwargs or making this constraint explicit.
Currently `check_bounds` will throw a generic `TypeError` if used on a function with more than one argument, because `wrapper` only accepts `x`. To make this safer, you could define `wrapper(*args, **kwargs)`, forward all arguments to `_func`, and explicitly check the relevant argument (e.g., `args[0]`). If the decorator is intentionally limited to single-argument functions, consider validating `_func`’s signature up front so incorrect usage fails with a clear error message.
```suggestion
'''
def check_bounds_wrapper(_func):
@functools.wraps(_func)
def wrapper(*args, **kwargs):
if not args:
raise TypeError(
"check_bounds-decorated functions must have at least one "
"positional argument to check"
)
x = args[0]
if min_value > x or x > max_value:
raise ValueError(f'argument {x} not in [{min_value}, {max_value}]')

<issue_to_address>
**issue (bug_risk):** Catching ValueError and using `e.message` will fail; use `str(e)` (and fix the typo) instead.
In Python 3, `ValueError` instances don’t have a `.message` attribute, so `e.message` will raise an `AttributeError` instead of showing the original error. Use `str(e)` or interpolate `e` directly, e.g.:
```python
except ValueError as e:
print(f"Exception raised as expected: {e}")
```
Also, fix the typo: `Excepton` → `Exception`.
