How to use chrome webdriver in selenium to download files in python?

To download files using the Chrome WebDriver in Selenium with Python, you can set the chrome_options to modify the browser settings. Here's an example:

from selenium import webdriver from selenium.webdriver.chrome.options import Options import time # Set the download directory download_dir = r'C:\path\to\your\download\directory' # Create Chrome options chrome_options = Options() chrome_options.add_argument('--headless') # Optional: Run Chrome in headless mode chrome_options.add_argument('--disable-gpu') chrome_options.add_argument('--no-sandbox') chrome_options.add_argument('--disable-dev-shm-usage') # Set download preferences prefs = { 'download.default_directory': download_dir, 'download.prompt_for_download': False, 'download.directory_upgrade': True, 'safebrowsing.enabled': False, 'safebrowsing.disable_download_protection': True, } chrome_options.add_experimental_option('prefs', prefs) # Create Chrome WebDriver driver = webdriver.Chrome(options=chrome_options) # Example: Navigate to a page with a download link driver.get('https://example.com') # Example: Find and click on the download link download_link = driver.find_element_by_xpath('//a[contains(@href, "download")]') download_link.click() # Optional: Wait for the file to download (add additional wait time as needed) time.sleep(5) # Close the browser driver.quit()

In this example:

  1. download_dir: Replace this with the path to the directory where you want to save the downloaded files.
  2. chrome_options: Set various options for Chrome, such as running in headless mode, disabling GPU, and specifying download preferences.
  3. prefs: Dictionary containing download preferences.
  4. add_experimental_option('prefs', prefs): Set the preferences in the Chrome options.
  5. Navigate to the page with the download link and click on it.
  6. Optional: Add a wait time to allow the file to download.

Note: The time.sleep(5) is used as an example wait time after clicking the download link. You may need to adjust the wait time based on the actual download time.

Make sure to replace the download link XPath and URL with the actual values from the website you are working with. Additionally, ensure that the Chrome WebDriver executable (chromedriver.exe) is in your system's PATH or provide the path explicitly when creating the webdriver.Chrome() instance.
