It accepts a URL as the argument. It accepts the following optional parameters\n\nOpens the URL in a new browser window, if possible.\n\nOpens the URL in a new browser tab.\n\nThe options are, naturally, mutually exclusive. Usage example\n\nBounded code example (external data; do not execute automatically):\n```bash\npython -m webbrowser -t \"https://www.python.org\"\n```\n\nThe following exception is defined\n\nException raised when a browser control error occurs.\n\nThe following functions are defined\n\nDisplay url using the default browser. If new is 0, the url is opened in the same browser window if possible. If new is 1, a new browser window is opened if possible. If new is 2, a new browser page (\"tab\") is opened if possible. If autoraise is True, the window is raised if possible (note that under many window managers this will occur regardless of the setting of this variable).\n\nReturns True if a browser was successfully launched, False otherwise.\n\nNote that on some platforms, trying to open a filename using this function, may work and start the operating system's associated program. However, this is neither supported nor portable.\n\nOpen url in a new window of the default browser, if possible, otherwise, open url in the only browser window.\n\nReturns True if a browser was successfully launched, False otherwise.\n\nOpen url in a new page (\"tab\") of the default browser, if possible, otherwise equivalent to open_new.\n\nReturns True if a browser was successfully launched, False otherwise.\n\nReturn a controller object for the browser type using. If using is None, return a controller for a default browser appropriate to the caller's environment.\n\nRegister the browser type name. Once a browser type is registered, the get function can return a controller for that browser type. If instance is not provided, or is None, constructor will be called without parameters to create an instance when needed. If instance is provided, constructor will never be called, and may be None.\n\nSetting preferred to True makes this browser a preferred result for a get call with no argument. Otherwise, this entry point is only useful if you plan to either set the BROWSER variable or call get with a nonempty argument matching the name of a handler you declare. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
