如何从Scala中的文本中删除数字？

Question

如何从Scala中删除数字形式的文本？

例如,我有这样的文字:

canon 40 22mm lens lock strength plenty orientation 321 .

删除后:

canon lens lock strength plenty orientation .

Answer 1

请尝试filter或filterNot

val text = "canon 40 22mm lens lock strength plenty orientation 321 ."
val without_digits = text.filter(!_.isDigit)

要么

val text = "canon 40 22mm lens lock strength plenty orientation 321 ."
val without_digits = text.filterNot(_.isDigit)
