What does Selenium .set_script_timeout(n) do and how is it different from driver.set_page_load_timeout(n)?

As per the Selenium-Python API Docs set_page_load_timeout(n) and set_script_timeout(n) both are timeout methods which are used to configure the webdriver instance to abide by during the program execution.

set_page_load_timeout(time_to_wait)

set_page_load_timeout(time_to_wait) sets the amount of time to wait for a page load to complete before throwing an error and is defined as :

    def set_page_load_timeout(self, time_to_wait):    """    Set the amount of time to wait for a page load to complete       before throwing an error.    :Args:     - time_to_wait: The amount of time to wait    :Usage:        driver.set_page_load_timeout(30)    """    try:        self.execute(Command.SET_TIMEOUTS, {        'pageLoad': int(float(time_to_wait) * 1000)})    except WebDriverException:        self.execute(Command.SET_TIMEOUTS, {        'ms': float(time_to_wait) * 1000,        'type': 'page load'})

set_script_timeout(time_to_wait)

set_script_timeout(time_to_wait) sets the amount of time that the script should wait during an execute_async_script (Javascript / AJAX Call) call before throwing an error and is defined as :

    def set_script_timeout(self, time_to_wait):    """    Set the amount of time that the script should wait during an       execute_async_script call before throwing an error.    :Args:     - time_to_wait: The amount of time to wait (in seconds)    :Usage:        driver.set_script_timeout(30)    """    if self.w3c:        self.execute(Command.SET_TIMEOUTS, {        'script': int(float(time_to_wait) * 1000)})    else:        self.execute(Command.SET_SCRIPT_TIMEOUT, {        'ms': float(time_to_wait) * 1000})
