使用正则表达式从python中的自由格式文本中提取电话号码 [英] Extracting phone numbers from a free form text in python by using regex

问题描述

我必须从自由形式的文本中提取电话号码.

I have to extract phone numbers from free form of texts.

如何在python中使用reg-ex来管理它?

How can I manage it by using reg-ex in python?

我发现一个是为了提取电子邮件地址. https://gist.github.com/dideler/5219706

I have found for one in order to extract e-mail addresses. https://gist.github.com/dideler/5219706

我已经通过使用电话号码正则表达式而不是电子邮件地址正则表达式实现了相同的方法，但是我无法获得输出.

I have implemented the same approach by using a phone number regex instead of e-mail address regex, but I couldn't get output.

def get_phoneNumber(text):
        phone_number = ""
        regex = re.compile("((\(\d{3,4}\)|\d{3,4}-)\d{4,9}(-\d{1,5}|\d{0}))|(\d{4,12})")

        for phoneNumber in get_phoneNumbers(text, regex):
                phone_number = phone_number + phoneNumber + "\n"

        return phone_Number

def get_phoneNumbers(s, regex):
        return (phoneNumber[0] for phoneNumber in re.findall(regex, s)

我该如何做到呢?

for match in re.finditer(r"\(?\b[2-9][0-9]{2}\)?[-. ]?[2-9][0-9]{2}[-. ]?[0-9]{4}\b", subject):
    # match start: match.start()
    # match end (exclusive): match.end()
    # matched text: match.group()
