As an Investment Banker, when advising a client on a potential merger and acquisition deal, it's important to have access to the necessary financial data and information. To ensure that all relevant details are considered, it's essential to check whether specific key data, such as 'some_key', is set within the configuration object. This can be achieved using the appropriate method from the igraph API.
### Response:
['from igraph import Configuration', '# Create Configuration object', 'config = Configuration()', "# Check if the configuration contains 'key'", "key = 'some_key'", 'has_key = key in config', "print('Configuration contains key:', has_key)"]
