Question

因此，我有一个提取电子邮件和电话号码的程序。我已经运行了，电话号码也很好。但是，电子邮件将继续导致：例如：3465Usjohnson@astate.eduUP批准而不是sjohnson@astate.edu 从中提取的环绕文本： 870-972-3465Usjohnson@astate.eduUP批准和副总理博士Lynita Cooksey870-972-2 030 870-972-2036Ulcooksey@astate.edu

在实际的PDF中，存在白色和间距，但是在复制和粘贴时，它们之间没有空格，因此也没有我收到的电子邮件。（它看起来像：enter image description here

#extract
extractedPhone = phoneRegex.findall(text)

allPhoneNumbers = []

#copy to clipboard

pyperclip.copy(results)

Answer 1

因此，因为我没有您的原始文本，所以我仅使用示例中的字符串。

查看以下两个正则表达式是否适合您。我还提供了第三点，这更加精确。

'(?<=\dU)[\w]+@[\w\.]+?(?=U|\s|$)'

。

'(?<=\dU)[\w]+@[\w]+\.[\w]+?(?=U|\s|$)'

。

示例测试

>>> import re


>>> string = '''3465Usjohnson@astate.eduUProvost instead of sjohnson@astate.edu The surround text that it is being extracted from: 870-972-3465Usjohnson@astate.eduUProvost and Vice ChancellorDr. Lynita Cooksey870-972-2 030 870-972-2036Ulcooksey@astate.edu'''


>>> re.findall('(?<=\dU)[\w]+@[\w\.]+?(?=U|\s|$)', string)

#Output
['sjohnson@astate.edu', 'sjohnson@astate.edu', 'lcooksey@astate.edu']




>>> re.findall('(?<=\dU)[\w]+@[\w]+\.[\w]+?(?=U|\s|$)', string)

#Output
['sjohnson@astate.edu', 'sjohnson@astate.edu', 'lcooksey@astate.edu']

。

更加精确一点，因为所有电子邮件均以.edu

结尾

'(?<=\dU)[\w]+@[\w]*\.edu(?=U|\s|$)'

。

示例测试

>>> string = '''3465Usjohnson@astate.eduUProvost instead of sjohnson@astate.edu The surround text that it is being extracted from: 870-972-3465Usjohnson@astate.eduUProvost and Vice ChancellorDr. Lynita Cooksey870-972-2 030 870-972-2036Ulcooksey@astate.edu'''


>>> re.findall('(?<=\dU)[\w]+@[\w]*\.edu(?=U|\s|$)', string)

#Output
['sjohnson@astate.edu', 'sjohnson@astate.edu', 'lcooksey@astate.edu']

Answer 2

我本人是Python的新手。如果文字是专门从“ astate.edu ”网站中提取的，我认为您可以使用此正则表达式：

text='70-972-3465Usjohnson@astate.eduUProvost and Vice ChancellorDr. Lynita Cooksey870-972-2 030 870-972-2036Ulcooksey@astate.edu'    
import re
email= re.findall('[a-z]+\@\w+\.edu',text)
#output
['sjohnson@astate.edu', 'lcooksey@astate.edu']

祝你好运！
