Why is this returning nil?

[Dark Ambient]

class User

def initialize(level, status)
@level = level
@status = status
end

def finda
if @status == "active"
print #{@level}
else
puts "user not exist"
end
end
end

user1 = User.new(1, "active")
user2 = User.new(1, "inactive")
user3 = User.new(2, "active")
user4 = User.new(3, "inactive")

user1.finda

Something wrong ..not sure
TIA

D> if @status == "active"

print @level

outside a string, # is a comment

D> else

print and puts return nil. As they are the last commands executed
their return statuses are returned.

Because methods return the value of the last statement. In this
case, both 'puts' and 'print' return nil, the actual output to the
screen is separate from the return value:

print "Hello\n"
Hello
=> nil
puts "Hello"
Hello
=> nil

My guess/advice would be to return the actual string you're
eventually going to output, and deal with the actual output elsewhere
in the code.

Hello!

You forgot quotes in line print #{@level}. Change it to "print
#{@level}" please.

 

[Alexey Vakhov]

Oh. Some mistake. Change it to

print " #{@level}"

of course

Wow..lot of answers, thanks to all.
It works and I've learned a few things in the process.
