--description--

You can remove a key-value pair from a dictionary by using the del keyword:

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

del my_dict['occupation']

Just before your for loop, 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 for loop.

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

for i, j in copper.items():
    print(i, j)
