Walkthrough

The updates involve modifying demo.py by removing the old my_function, introducing a new hello function that returns a greeting string, and adding descriptive docstrings. In testing.py, only a formatting change was made by adding a blank line before the function definition. The GitHub Actions workflow for pylint was expanded to test Python versions 3.8, 3.9, and 3.10.

Changes

File(s) Change Summary
demo.py Removed my_function, added module and function docstrings, introduced new hello function returning a greeting string, updated function call.
testing.py Added a blank line before the hello function definition for formatting.
.github/workflows/pylint.yml Expanded Python versions tested in pylint workflow matrix to include 3.8, 3.9, and 3.10.

Poem

In the garden of code, a greeting now grows,
"Hello dosto" is what the new function bestows.
Old numbers retired, new words take their place,
With docstrings and spacing, we tidy the space.

🛠️ Refactor suggestion

Top-level call executes on import and its return value is discarded

Calling hello() at module import time can cause side effects when the module is imported elsewhere and the result is silently ignored.
Wrap the invocation in a __main__ guard and explicitly use the returned string (e.g. print it).

-hello()
+if __name__ == "__main__":
+    print(hello())

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In demo.py at line 8, the call to hello() is executed at import time and its
return value is discarded, which can cause unintended side effects. To fix this,
wrap the call to hello() inside an if __name__ == "__main__": block and
explicitly handle the return value, for example by printing it.

6-6: Top-level call still executed on import – comment already provided earlier

The unconditional hello() invocation remains, leading to side-effects on import. See the prior review for the recommended if __name__ == "__main__": guard.

⚠️ Potential issue

Indentation mismatch causes a hard SyntaxError – the module cannot be imported

The docstring is indented with 5 spaces whereas the enclosing def block uses 4. This triggers the SyntaxError: unindent does not match any outer indentation level reported by both Ruff and Pylint, and the file fails to load.

-def hello():
-     """Return a demo greeting message."""  # ← Proper function docstring
-    return "hello dosto"
+# Function-level indentation must be consistent (4 spaces)
+def hello():
+    """Return a demo greeting message."""
+    return "hello dosto"
+

+# Only execute when run directly, not on import

In demo.py around lines 2 to 3, the function docstring is indented with 5 spaces
while the enclosing def block uses 4 spaces, causing a SyntaxError. Fix this by
adjusting the docstring indentation to match the def block's 4 spaces exactly,
ensuring consistent indentation throughout the function.

9-9: Avoid executing code at import time – wrap hello() in a __main__ guard

Calling hello() at the top level means the function runs (and its return value is discarded) whenever any module imports demo. This breaks the “no-side-effects on import” rule and was already flagged in a previous review.

-hello()
+if __name__ == "__main__":
+    # Explicitly use the returned value
+    print(hello())

4-6: Consider adding type hints for clarity

PEP-484 style annotations improve readability and help static analysis:

-def hello():
-    """Return a demo greeting message."""
-    return "hello dosto"
+def hello() -> str:
+    """Return a demo greeting message."""
+    return "hello dosto"

7-7: Top-level call still executes on import – wrap with __main__ guard
Same issue flagged in the previous review remains: executing hello() at import time introduces side-effects and discards the result. Guard the call and handle the return value explicitly.
