Regular Expressions

• • List all the matched regex in a string

## Suppose we have a text with many email addresses

str = 'My official email id is debojyotib@nrifintech.com and my personal email id is debjyoti.mail@gmail.com '

import re

## Here re.findall() returns a list of all the found email strings

emails = re.findall(r'[\w\.-]+@[\w\.-]+', str) ## ['alice@google.com', 'bob@abc.com']

print '\nThe String is : ', str, '\n'

print 'The number of emails in the string : ', len(emails), '\n'
