Ruby - Deleting an element from a hash

I have the following hash:

my_info = {'first_name' => 'xyz', 'last_name' => 'mnl', 'age' => 27}

When I try to delete the age key as follows:

my_info.delete['age']

I get the following:

r.rb:5:in `delete': wrong number of arguments (0 for 1) (ArgumentError)
        from r.rb:5

Why is that?

Thanks.

The reason for that is because delete is a method so you must use parenthesis instead like this:

my_info.delete('age')
