""" This code is a scraper for the metro.ca website. It is designed to run with Python 3.8.2 Running this code with a different version of Python may result in errors such as 'undetected_chromedriver' and 'distutils' errors.
Review:
-
Commented Code: Some lines of code, like the headless option and disable notifications, are commented out. Ensure these comments reflect a specific purpose, such as troubleshooting or development version considerations.
-
Logging: Logging is implemented to capture debug information in the 'Metro.log' file. Consider adding more fine-grained logging messages, such as success notifications, exceptions, or detailed steps to aid in troubleshooting and debugging.
-
Exception Handling: Generally, handling exceptions is a good practice. However, in some places, exceptions are caught without handling or logging the error. Make sure to review these exceptions and implement appropriate error handling or logging for a more robust application.
-
Error Messages: The variable 'p' is assigned with a string value in various exception cases, but it is not used or logged elsewhere. Ensure that error messages and logging capture meaningful information about encountered errors.
-
Code Formatting: Format the code consistently to improve readability and maintainability. Follow PEP 8 guidelines, including indentation with four spaces, consistent capitalization, proper space usage, and line length limitations.
-
Code Separation: Consider breaking down the large
scrape_website()method into smaller, more manageable functions or methods. This modular approach makes the code easier to maintain, test, and understand. -
Chrome Driver: Ensure the 'chromedriver.exe' path specified in the
run_browser()method is correctly set for the target environment. -
Implicit Waits: Implementing implicit waits (e.g.,
driver.implicitly_wait(10)) can help reduce explicit wait statements, making the code more efficient. -
Reusability: Consider making the code more reusable by accepting the target URL as a command-line argument or as a parameter to the
run_browser()method.
Overall, the code demonstrates a functional web scraper for the metro.ca website. Addressing the mentioned points will help enhance its functionality and maintainability. """
