--description--

The same syntax can be used to change the value of an existing key.

Just before the print() call, access the 'species' key and reassign its value to 'Cavia porcellus'.

--hints--

You should reassign the copper['species'] to the string 'Cavia porcellus' before the print() call.

js
({ test: () => {
    const commentless_code = __helpers.python.removeComments(code);
    assert.match(commentless_code, /^copper\s*\[\s*("|')species\1\s*\]\s*=\s*("|')Cavia porcellus\2\s+^print\s*\(\s*copper\s*\)/m)
  }
})

--seed--

py
--fcc-editable-region--
copper = {
    'species': 'guinea pig',
    'age': 2
}
copper['food'] = 'hay'

print(copper)
