'WebDriver' object has no attribute 'switch_to_window'

This error message indicates that you are trying to use the 'switch_to_window' method on a WebDriver object, but this method does not exist in the WebDriver class.

The correct method to switch between windows in Selenium WebDriver is 'switch_to.window()'. Here is an example of how to use it:

# Get the current window handle
current_window = driver.current_window_handle

# Open a new window
driver.execute_script("window.open('https://www.google.com');")

# Switch to the new window
for window_handle in driver.window_handles:
    if window_handle != current_window:
        driver.switch_to.window(window_handle)
        break

# Do something in the new window
print(driver.title)

# Switch back to the original window
driver.switch_to.window(current_window)
