Expect the unexpected, but get what you want.

@anticipate(int)
def get_int():
  return '1'

assert get_int() == 1

@anticipate(str)
def get_str():
  return 22

assert get_str() == '22'

@anticipate([str])
def get_strs(*args):
  return args

assert list(get_strs(1, 2, 3)) == ['1', '2', '3']

Works much better with your own objects or with SpringField

• Dropped support for Python 2.6, added support for Python 3.7.
• Cleaned up code formatting

• Fixed issue that prevented use of an adaptable object (has an adapt method) as an anticipated list of type.

• Change so that anticipating an iterable using [type] will always return a list instead of generator
• Added anticipate_input_factory to make it easier to implement input handlers that need to inject values or handle input errors differently
• Made it so you can use any object that implements adapt as an anticipate type so you can use SpringField fields as input types
• Improved error messages
• Split anticipate input and output handling into separate functions to make it easier to intercept input or output handling
• Check that the params being anticipated exist in the function signature
