Selenium with Python: Web Automation Tutorial

• Selenium is an automation framework for programmatically controlling web browsers.
• Selenium automates repetitive tasks, such as logins, form submissions, and data extraction.
• It performs web scraping (data gathering from websites).
• Selenium tests web applications by checking UI functionality.
• This tutorial covers the fundamental concepts of Selenium with Python.

Selenium Essentials

• webdriver: Controls the web browser.
• By: Finds elements on a webpage.
• Keys: Simulates keyboard input.
• Select: Handles dropdown menus.
• Service: Manages WebDriver execution.
• webdriver-manager: Auto-installs WebDriver.
• dotenv: Stores secure credentials.
• time: Handles execution delays.

Selenium Core Functions

• webdriver.Chrome(): Opens a Chrome browser.
• driver.get(url): Navigates to a website.
• driver.quit(): Closes the browser.
• driver.refresh(): Refreshes the page.
• By.ID: Finds an element by ID.
• By.NAME: Finds an element by name attribute.
• Keys.RETURN: Simulates pressing Enter.
• Select.select_by_index(n): Selects option by position.
• time.sleep(n): Pauses execution for n seconds.

• Imports login_svts from auth module.
• Imports the By class for locating elements.
• Imports Select for handling dropdown menus.
• Imports time and datetime modules.
• Logs in using login_svts() and exits if login fails.
• Navigates to the specified URL.
• Selects an option from a dropdown menu using its ID and index.
• Clicks a search button using its ID.
• Creates a description string including the current date.
• Enters the description into a text field using its ID.
• Clicks a button using its ID.
• Refreshes the page three times and attempts to download a file.
• If a "Get File" link is found, it is clicked and a success message is printed.
• Sleeps for pauses in execution.
• If an exception occurs, the error is printed.
• The browser is closed in the finally block.
