How to change Hash values?

Question

I\'d like to replace each value in a hash with value.some_method.

For example, for given a simple hash:

{\"a\" => \"b\",         


        

Answer 1

Try this function:

h = {"a" => "b", "c" => "d"}
h.each{|i,j| j.upcase!} # now contains {"a" => "B", "c" => "D"}.
