I am trying to get all email address from a text file using regular expression and Python but it always returns NoneType while it suppose to return the email. For example:
content = 'My email is [email protected]'
#Compare with suitable regex
emailRegex = re.compile(r'(^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$)')
mo = emailRegex.search(content)
print(mo.group())
I suspect the problem lies in the regex but could not figure out why.
Because of spaces in content; remove the ^ and $ to match anywhere:
([a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+)
Try this one as a regex, but I am completely not sure whether it will work for you:
([^@|\s]+@[^@]+.[^@|\s]+)
| inside character class is a red flag - are you sure you want to exclude it from the character class?
| should not be used to say "alternation" in character class. [@\s] is already an alternation of 2 choices @ or space character class. The extra | will add the literal | to the list of alternation.| should not be used as "alternation" in character class.Your regular expression doesn't match the pattern.
I normally call the regex search like this:
mo = re.search(regex, searchstring)
So in your case I would try
content = 'My email is [email protected]'
#Compare with suitable regex
emailRegex = re.compile(r'gmail')
mo = re.search(emailRegex, content)
print(mo.group())`
You can test your regex here: https://regex101.com/ This will work:
([a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$)
r'[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+'.@only.
