Get specific word from a sentence if it has a certain character-CodePudding

I'm trying to get one single word out of a string if it contains a certain character.

I want to do something like this:

string = 'My email is [email protected] and I use it a lot.'

if '@' in string:
    return email

But how can I get python to know exactly where the keyword is and return it's value.

In this case it would return [email protected]

CodePudding user response：

You can also use regex for your purposes. In this regex pattern \S* means "Any non-whitespace character". You can test the regular expression here.

import re

string = 'My email is [email protected] and I use it a lot.'

search_word = re.search(r'(\S*)@(\S*)', string)
if search_word:
    print(search_word.group())
else:
    print("Word was not found.")

CodePudding user response：

Using list comprehension:

emails = [i for i in string.split() if '@' in i]

Output:

['[email protected]']

CodePudding user response：

Use regular expression to extract your pattern of interest, for example:

import re
email = re.search('\w @\w ([.]\w ) ', string).group(0)

CodePudding user response：

match=re.search(r'([^\s]*@[^\s]*)',string)
if match and match.group(0): print(match.group(0))
