Because in a python RE, \? is a literal '?', not a '0 or 1 of repeat'. For grep you need the \? to give ? its special meaning. a regexp for egrep or grep -E will be closer to what you want for python. You want ^\.?j\.?o\.?e\.?b\.?l\.?o\.?w xxx \+.*@gmail\.com where I'm unsure about the ' xxx ' part because I don't understand what '\ ?' is supposed to do? Or instead of the above and to account for multiple '.' maybe ^\.*j\.*o\.*e\.*b\.*l\.*o\.*w\.*\+.*@gmail\.com which says zero or more dots followed by j followed by zero or more dots followed by o, etc., followed by w followed by zero or more dots followed by + followed by anything followed by @gmail.com.
