Create a function that outputs directory numbers (dictionary keys) by the selected value. directories = { '1': ['2207 876234', '11-2'], '2': ['10006'], '3': [] } For example: input = 2207 876234 output = 1 input = 11-2 output = 1 input = 10006 output = 2 input = 1434 output = 'Nothing found'

def search_goods():
    global directories
    input_number = input('Input directory number: ')
    for key, value in directories.items():
        for item in value:
            if input_number == item:
                return key
    return 'Nothing found'
