24-31: Consider moving usage example to a guarded block.This usage block will execute every time the module is imported. If this is example code, wrap it in an
if __name__ == '__main__':guard to prevent it from running during imports.Apply this diff:
-# Usage -env_vars = load_env_file() -password = env_vars.get('PASSWORD') - -if password: - print("Password found!") -else: - print("Password not found") +if __name__ == '__main__': + # Usage example + env_vars = load_env_file() + password = env_vars.get('PASSWORD') + + if password: + print("Password found!") + else: + print("Password not found")
2-21: Consider using python-dotenv instead of a custom implementation.The
python-dotenvlibrary is a well-established, battle-tested solution for loading.envfiles. It handles edge cases (quote escaping, multiline values, variable expansion) that this custom implementation doesn't address.Install the library:
pip install python-dotenvThen replace the custom function with:
from dotenv import load_dotenv # Load .env file load_dotenv() # Access variables using os.environ password = os.environ.get('PASSWORD') if password: print("Password found!") else: print("Password not found")

1-1: LGTM!The
osimport is appropriate for the file operations used in this module.
2-7: LGTM!The function signature, docstring, and early return pattern for missing files are well-implemented.

Add error handling for I/O operations.
The function checks file existence but doesn't handle other potential I/O errors (permission denied, file locked, TOCTOU race condition, disk errors). These would cause unhandled exceptions.
Apply this diff to add error handling:
- with open(filepath, 'r', encoding='utf-8') as f:
- for line in f:
- line = line.strip()
- # Skip empty lines and comments
- if line and not line.startswith('#'):
- # Split on first = sign
- if '=' in line:
- key, value = line.split('=', 1)
- # Remove quotes if present
- value = value.strip().strip('"').strip("'")
- env_vars[key.strip()] = value
+ try:
+ with open(filepath, 'r', encoding='utf-8') as f:
+ for line in f:
+ line = line.strip()
+ # Skip empty lines and comments
+ if line and not line.startswith('#'):
+ # Split on first = sign
+ if '=' in line:
+ key, value = line.split('=', 1)
+ # Remove quotes if present
+ value = value.strip().strip('"').strip("'")
+ env_vars[key.strip()] = value
+ except (IOError, OSError) as e:
+ # Log the error or handle it appropriately
+ print(f"Warning: Could not read {filepath}: {e}")
+ return env_vars📝 Committable suggestion
‼️ IMPORTANT
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 Dice project/Dice.py around lines 9 to 20, wrap the file open/read loop in a
try/except that catches OSError (and optionally UnicodeDecodeError) so
permission errors, locked files, disk errors, or read failures don’t crash the
process; on exception log or return a clear error (include the filepath and
exception message) and re-raise or return a controlled error value as
appropriate for this module, ensuring the with-open remains inside the try so
the file handle is only created if open succeeds and resources are still cleaned
up.

Specify encoding for cross-platform compatibility.
Opening the file without an explicit encoding can cause issues on different platforms. Windows defaults to cp1252 while Unix systems use UTF-8, which could lead to UnicodeDecodeError or incorrect character interpretation.
Apply this diff to specify UTF-8 encoding:
- with open(filepath, 'r') as f:
+ with open(filepath, 'r', encoding='utf-8') as f:📝 Committable suggestion

In Dice project/Dice.py around line 9, the file is opened without an explicit
encoding which can cause cross-platform decoding errors; update the open call to
specify UTF-8 by passing encoding='utf-8' to open (i.e., change the with
open(...) line to include encoding='utf-8') so the file is read consistently on
all platforms.

Fix quote stripping logic to handle pairs correctly.
The current approach strips all quote characters from both ends, not matched pairs. This can corrupt values like "it's" (becomes it) or handle mixed quotes unpredictably.
Apply this diff to properly handle matched quote pairs:
- # Remove quotes if present
- value = value.strip().strip('"').strip("'")
+ # Remove surrounding quotes if present (matched pairs only)
+ value = value.strip()
+ if len(value) >= 2 and ((value[0] == '"' and value[-1] == '"') or (value[0] == "'" and value[-1] == "'")):
+ value = value[1:-1]Committable suggestion skipped: line range outside the PR's diff.

In Dice project/Dice.py around line 18, the current value =
value.strip().strip('"').strip("'") naively removes all quote characters and
corrupts strings with internal quotes; instead, trim whitespace first, then if
the string is at least two characters and the first and last characters are a
matching pair of quotes (both " or both '), remove exactly that outer pair only;
otherwise leave the internal quotes intact (do not indiscriminately strip quote
characters).
