Yes, the expression "no ~, no ~" is an idiom. It is used to express that without one thing, the other can't happen because the first thing is required for the second thing to happen. This expression is very short and is more common to see in written English, especially on signs. Ex: No shoes, no service. Ex: Sorry, we're cash only. No cash, no food.
