Sean Penn's paparazzi attack case is now over and out -- almost a year after Sean plead no contest to vandalism ... TMZ has learned Penn and the pap have settled the photog's civil suit.
Penn got 36 months probation and was ordered to perform 300 hours of community service stemming from an incident where he kicked a photog who was trying to film him.
The photog filed a civil suit, claiming he suffered a knee injury as a result of Penn's attack.
Both sides signed the settlement docs today. No word on how much Penn had to shell out.
