## Discussion

Discussion The format(_:) instance method generates a string from the provided sequence. Once you create a style, you can use it to format similar sequences multiple times. For example: let percentStyle = ListFormatStyle<IntegerFormatStyle.Percent, [Int]>(memberStyle: .percent) percentStyle.format([92, 98]) // 92% and 98% percentStyle.format([67, 72, 99]) // 67%, 72%, and 99%
