In addition to clubs you may need other items. Most golf courses and practice facilities sell inexpensive balls or used balls that are fine for beginners.
Golf balls come in different types for different types of players.
The price is more important than the quality of the ball initially, but if you want to focus on one variable choose the hard golf balls, one or two-piece balls with a hard cover. These balls are more durable and actually go slightly farther that the other types of balls. Many golf courses or practice facilities sell used golf balls, which are usually much less expensive than new balls and work just fine. You will need a bag to carry your clubs. Golf shoes are optional for beginners, as are gloves in my opinion.
