因此，我目前正在执行一项任务，要求我们从文本文档中提取电话号码、电子邮件和网站。讲师要求我们将其输出到元组列表中，每个元组都包含初始索引、长度和匹配项。以下是一些示例：[(1,10'9099000008')，(35,16'contact@viva.com')]因为有三种不同的要求需要实现。如何将它们全部放入元组列表中？我已经想到了三个正则表达式，但我不能真正将它们放在一个列表中。我应该创建一个新的表达式来描述这三种情况吗？谢谢你的帮助。
result = []
# Match with RE
email_pattern = r'[w.-]+@[w.-]+(?:.[w]+)+'
email = re.findall(email_pattern, string)
for match in re.finditer(email_pattern, string):
print(match.start(), match.end() - match.start(), match.group())
phone_pattern = r'(?d{3})?[-.s]?d{3}[-.s]?d{4}'
phone = re.findall(phone_pattern, string)
for match in re.finditer(phone_pattern, string):
print(match.start(), match.end() - match.start(), match.group())
website_pattern = '(https?://(?:www.|(?!www))[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9].[^s]{2,}|www.[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9].[^s]{2,}|https?://(?:www.|(?!www))[a-zA-Z0-9]+.[^s]{2,}|www.[a-zA-Z0-9]+.[^s]{2,})'
web = re.findall(website_pattern, string)
for match in re.finditer(website_pattern, string):
print(match.start(), match.end() - match.start(), match.group())
我的输出：

不是printing而是appending到resultlist然后printit，即更改
print(match.start(), match.end() - match.start(), match.group())
至
result.append((match.start(), match.end() - match.start(), match.group()))
其他人也是如此，然后在结束时
print(result)
