Answer 1

您可以使用re.findall使用regexp r'"xlarge":"(.*?)"提取所有xlarge url

>>> re.findall(r'"xlarge":"(.*?)"', text)
['https://i.ebayimg.com/00/s/NTU5WDEwMjY=/z/TQMAAOSwkrFaZqhh/$_20.PNG', 'https://i.ebayimg.com/00/s/ODAwWDgwMA==/z/uX0AAOSwvGlaZqhU/$_20.JPG', 'https://i.ebayimg.com/00/s/NjMwWDk2MA==/z/n58AAOSwp-RaZqhn/$_20.PNG']
