Discipline encourages change, while punishment inhibits it. It accounts for an individual child's emotional maturity while gently, firmly, giving her the tools she needs to obey your commands. It rewards positive actions while correcting negative ones without crushing the child's spirit and sense of wellbeing.
Punishment is a bigger person forcing a smaller one to do as directed, whether the little one can do as ordered or not. It teaches children how to bully their smaller peers, siblings, and others long before it teaches them how to lovingly correct another's aberrant behavior. There is NEVER good reason to hit a child, so spanking is definitely out.
Discipline is the consistent, firm, and loving enforcement of previously established boundaries. It consists of helping a child understand why a rule is necessary, proving that you will always enforce it, and that the restrictions increase with each repeat of the offense that engenders them. It begins in your heart, as you recall how badly you felt when your parents grounded you, removed a treasured toy from your toybox until your restriction ended, and how overjoyed you were when they returned it.
It ends when the child learns her lesson and not before then, lest you confuse her. It persists in spite of temper tantrums, through attempts to avoid it, and until you are certain your baby has learned the lesson the discipline was intended to impart to her.
Punishment, contrarily, is an arbitrary act usually inspired by a parent's anger with a child for overstepping a boundary unawares or for committing a known infraction repeatedly. It does not account for a child's seeking your affection in a negative fashion because she is not getting it any other way. It does not permit an occasional lapse or episode of forgetfulness.
It implies that you are a perfect person, which your child already knows you are not. It robs a child of choices, personal responsibility for her actions, and otherwise discourages change. If you could not keep the rule for which you punish your child, then you have no business issuing edicts and insisting that she obey it either.
Discipline pulls a child back from rushing traffic and gently scolds her for scaring you, whereas punishment permits the child into the flow and risks her death just to prove that playing with fast-moving cars is dangerous. Discipline insists that a child do as instructed, but punishment torments her into tractibility. Discipline teaches listening skills, whereas punishment encourages a child to ignore you.
