--description--

You can remove a key-value pair from a dictionary by using the del keyword. The syntax is the following:

my_dict = {
    'name': 'Michael',
    'occupation': 'Lumberjack`
}

del my_dict['occupation']

Just before your print() call, use the del keyword to delete the age key and its value from copper.

--hints--

You should use the del keyword to delete copper['age'] before the print() call.

({ test: () => assert.match(code, /^del\s+copper\[\s*("|')age\1\s*\].*^print\s*\(\s*copper\s*\)/ms) })
