⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Add error handling for file operations.

The function lacks error handling for potential I/O failures (permission denied, disk full, invalid path, etc.). Without proper exception handling, these errors will propagate as unhandled exceptions, making it difficult for users to understand what went wrong.

🛡️ Proposed fix with error handling 
 def write_abc(filename: str = "abc_output.txt") -> None:
     """Write the string 'ABC' to the specified file."""
-    with open(filename, "w", encoding="utf-8") as f:
-        f.write("ABC")
-    print(f"Successfully wrote 'ABC' to {filename}")
+    try:
+        with open(filename, "w", encoding="utf-8") as f:
+            f.write("ABC")
+        print(f"Successfully wrote 'ABC' to {filename}")
+    except (OSError, IOError) as e:
+        print(f"Error writing to {filename}: {e}")
+        raise

In `@write_abc.py` around lines 6 - 10, The write_abc function currently opens and
writes to a file without handling I/O errors; wrap the open/write block in a
try/except that catches OSError (or a broader Exception if desired), and on
exception print/log a clear, user-friendly message that includes the filename
and the exception message (e.g., "Failed to write 'ABC' to {filename}:
{error}"), then either return an error indicator (False) or re-raise the
exception depending on the calling contract so callers can handle failures;
update write_abc to ensure resources are still closed (keep the with block
inside the try) and avoid letting raw I/O exceptions propagate unhandled.
