Set the Path below format.
driver = webdriver.Chrome('C:\Webdrivers') # Optional argument, if not specified will search path.

Other Formats:
On Windows, while mentioning the chromedriver binary path you have to either use the single front slash (/) along with the raw (r) switch or you have to use the escaped back slash (\\)

Example:
driver = webdriver.Chrome(executable_path=r'C:/Utility/BrowserDrivers/chromedriver.exe')
