passing dictionay as argument

[Arshpreet Singh]

I have to pass dictionary as function argument for following code:

</code>
import authorize

authorize.Configuration.configure(
    authorize.Environment.TEST,
    'api_login_id',
    'api_transaction_key',
)

result = authorize.Transaction.sale({
    'amount': 40.00,

    'credit_card': {
        'card_number': '4111111111111111',
        'expiration_date': '04/2014',
        'card_code': '343',
    }

})

result.transaction_response.trans_id

</code>

I want to define 'credit-card' dictionary as argument in the function as 
follows but it returns syntax error:

</code>

# define dictionary outside the function call: 
credit_card={
        'card_number': '4111111111111111',
        'expiration_date': '04/2014',
        'card_code': '343',
    }

import authorize

authorize.Configuration.configure(
    authorize.Environment.TEST,
    'api_login_id',
    'api_transaction_key',
)

result = authorize.Transaction.sale({'amount': 40.00,credit_card})

result.transaction_response.trans_id

it returns following error:

result = authorize.Transaction.sale({40.00,credit_card})
TypeError: unhashable type: 'dict'

Do I need to make changes in authorize.Transaction.sale() source code?
