Regex to match only letters

Question

How can I write a regex that matches only letters?

Answer 1

pattern = /[a-zA-Z]/

puts "[a-zA-Z]: #{pattern.match("mine blossom")}" OK

puts "[a-zA-Z]: #{pattern.match("456")}"

puts "[a-zA-Z]: #{pattern.match("")}"

puts "[a-zA-Z]: #{pattern.match("#$%^&*")}"

puts "[a-zA-Z]: #{pattern.match("#$%^&*A")}" OK
