This regex works well for me. 这个正则表达式对我来说效果很好。 When I check on regex match website. 当我检查正则表达式匹配网站时。 But when I use in actual code, it gives me wrong result 但是当我在实际代码中使用它会给我错误的结果
>>> text = 'my phone is +31 478-511014 and +91 900 133 5555'
>>> mobile = re.findall(r'\+?(\d*)\s?\(?(\d*)\)?\s?(\d*)[\s-]?(\d*)\s?(\d*)\s?(\d*)\s?', text)
>>> mobile
[('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('31', '478', '', '511014', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('', '', '', '', '', ''), ('91', '900', '133', '5555', '', ''), ('', '', '', '', '', '')]
Am I doing something wrong? 难道我做错了什么？

如果您遇到自己的问题，该工具应该可以工作：
[(+\d]\d[-\d\s()]*\d

it's working if you replace one of the * to + 如果您将*之一替换为+，则可以正常工作
mobile = re.findall(r'+?(\\d+)\\s?(?(\\d*))?\\s?(\\d*)[\\s-]?(\\d*)\\s?(\\d*)\\s?(\\d*)\\s?', text) mobile = re.findall（r'+？（\\ d +）\\ s？（？（\\ d *））？\\ s？（\\ d *）[\\ s-]？（\\ d *）\\ s？（\\ d *）\\ s？（\\ d *）\\ s？'，文本）
