Unless
Good! Now let’s review the unless
statement.
problem = false print "Good to go!" unless problem
Remember, this is basically a short hand if
statement. It will do whatever you ask unless
the condition is true
. In our example, problem
is false
, so we don’t have a problem. We print Good to go!
Instructions
1.
Create an unless
statement in the editor. The statement should print something to the console.
