Answer by Vladimir Kolenov for Webdriver Screenshot in Python

Sure it isn't actual right now but I faced this issue also and my way:Looks like 'save_screenshot' have some troubles with creating files with space in name same time as I added randomization to filenames for escaping override.

Here I got method to clean my filename of whitespaces (How do I replace whitespaces with underscore and vice versa?):

def urlify(self, s):    # Remove all non-word characters (everything except numbers and letters)    s = re.sub(r"[^\w\s]", '', s)    # Replace all runs of whitespace with a single dash    s = re.sub(r"\s+", '-', s)    return s

then

driver.save_screenshot('c:\\pytest_screenshots\\%s' % screen_name)

where

def datetime_now(prefix):    symbols = str(datetime.datetime.now())    return prefix +"-"+"".join(symbols)screen_name = self.urlify(datetime_now('screen')) +'.png'
