As of the time of writing this, the names ``C``, ``O``, ``S``, ``I``, ``N``, ``E``, and ``Q`` are colliding with names defined in SymPy. If you import them from both ``sympy.abc`` and ``sympy``, the second import will "win". This is an issue only for * imports, which should only be used for short-lived code such as interactive sessions and throwaway scripts that do not survive until the next SymPy upgrade, where ``sympy`` may contain a different set of names. 2. This module does not define symbol names on demand, i.e. ```from sympy.abc import foo``` will be reported as an error because ``sympy.abc`` does not contain the name ``foo``. To get a symbol named `'foo'`, you still need to use ``Symbol('foo')`` or ``symbols('foo')``. You can freely mix usage of ``sympy.abc`` and ``Symbol``/``symbols``, though sticking with one and only one way to get the symbols does tend to make the code more readable. iÿÿÿÿ(tprint_functiontdivisionNi(tSymboltsymbols(tgreeks(texec_sa, b, c, d, e, f, g, h, i, jsk, l, m, n, o, p, q, r, s, tsu, v, w, x, y, zsA, B, C, D, E, F, G, H, I, JsK, L, M, N, O, P, Q, R, S, TsU, V, W, X, Y, Zsalpha, beta, gamma, deltasepsilon, zeta, eta, thetasiota, kappa, lamda, musnu, xi, omicron, pisrho, sigma, tau, upsilonsphi, chi, psi, omegatlambdatlamdacC sÃi}td|ƒi}i}xt|r•|jƒ\}}|tkrft|ƒ||>> from sympy import S >>> from sympy.abc import _clash1, _clash2, _clash >>> S("Q & C", locals=_clash1) And(C, Q) >>> S('pi(x)', locals=_clash2) pi(x) >>> S('pi(C, Q)', locals=_clash) pi(C, Q) Note: if changes are made to the docstring examples they can only be tested after removing "clashing" from the list of deleted items at the bottom of this file which removes this function from the namespace. sfrom sympy import *(Rtpopitemt_greekRtremovet_latintupdate(tnstclash1tclash2tkt_tclash((s(lib/python2.7/site-packages/sympy/abc.pytclashingIs       (bt__doc__t __future__RRtstringtcoreRRtcore.alphabetsRtcore.compatibilityRtatbtctdtetftgthtitjRtltmtntotptqtrtstttutvtwtxtytztAtBtCtDtEtFtGtHtItJtKtLtMtNtOtPtQtRtStTtUtVtWtXtYtZtalphatbetatgammatdeltatepsilontzetatetatthetatiotatkappaRtmutnutxitomicrontpitrhotsigmattautupsilontphitchitpsitomegatlistt ascii_lettersR R R tappendRt_clash1t_clash2t_clash(((s(lib/python2.7/site-packages/sympy/abc.pyts0 ****    ,
