The motivation for this is to provide simple user interfaces. The user can call a function with regular tuples in the argument, and the wrapper will convert them to Tuples before handing them to the function. >>> from sympy.core.containers import tuple_wrapper >>> def f(*args): ... return args >>> g = tuple_wrapper(f) The decorated function g sees only the Tuple argument: >>> g(0, (1, 2), 3) (0, (1, 2), 3) c sYg}xC|D];}t|ƒtkr;|jt|Œƒq |j|ƒq Wˆ||ŽS(N(R(R!tappendR (Rtkw_argstnewargsR (tmethod(s4lib/python2.7/site-packages/sympy/core/containers.pyt wrap_tuples¨s  ((RGRH((RGs4lib/python2.7/site-packages/sympy/core/containers.pyt tuple_wrapper•stDictcB s’eZdZd„Zd„Zd„Zed„ƒZd„Zd„Z d„Z d„Z d „Z dd „Zd „Zd „Zed „ƒZRS(s; Wrapper around the builtin dict object The Dict is a subclass of Basic, so that it works well in the SymPy framework. Because it is immutable, it may be included in sets, but its values must all be given at instantiation and cannot be changed afterwards. Otherwise it behaves identically to the Python dict. >>> from sympy.core.containers import Dict >>> D = Dict({1: 'one', 2: 'two'}) >>> for key in D: ... if key == 1: ... print('%s %s' % (key, D[key])) 1 one The args are sympified so the 1 and 2 are Integers and the values are Symbols.
