Ruby skips if statements -

i have ruby program here w/c consists of hashes. when user enters l or p or sc check if computer generated key matches criteria on first variable w/c player or user. if matches criteria return won. if it's not return loose. otherwise if it's same print tie.

my_choices = {   'l' => 'light',  'p' => 'paper',   'sc' => 'scan', }  def test?(first, second)   (first == 'p' && second == my_choices ['l']) ||   (first == 'l' && second == my_choices ['p']) ||   (first == 'sc' && second == my_choices ['sc']) ||   (first == 'l' && second == my_choices ['l']) end   def print_results(player, computer)   if test?(player, computer)     puts("you won!")   elsif test?(computer, player)     puts("computer won! loose!")   else     puts("it's tie!")   end end  puts "enter key: " choice = gets().chomp() computer_choice = my_choices.values.sample print_results(choice, computer_choice) puts("you chose: #{choice}, computer choose: #{computer_choice}" 

with codes above, code skipping codes , prints "it's tie" don't missing here. idea?

you're getting user's input , testing against 'rock', 'paper' , 'scissors', you've stated user entering 'l', 'p', , 'sc' test never evaluate true

as example, saving rps.rb , running:

> ruby rps.rb  enter key:  rock won! chose: rock, computer choose: light
