Transform expressions that match source into expressions that match target treating all ``variables`` as wilds. Examples ======== >>> from sympy.abc import w, x, y, z >>> from sympy.unify.rewrite import rewriterule >>> from sympy import default_sort_key >>> rl = rewriterule(x + y, x**y, [x, y]) >>> sorted(rl(z + 3), key=default_sort_key) [3**z, z**3] Use ``condition`` to specify additional requirements. Inputs are taken in the same order as is found in variables. >>> rl = rewriterule(x + y, x**y, [x, y], lambda x, y: x.is_integer) >>> list(rl(z + 3)) [3**z] Use ``assume`` to specify additional requirements using new assumptions. >>> from sympy.assumptions import Q >>> rl = rewriterule(x + y, x**y, [x, y], assume=Q.integer(x)) >>> list(rl(z + 3)) [3**z] Assumptions for the local context are provided at rule runtime >>> list(rl(w + z, Q.integer(z))) [z**w] Tc3srt|idD]-rfddDsq r$t|s$q t}t|tr3t|}|Vq dS)N) variablescsg|]}||qSr)get).0varmatchrg/var/www/html/construction_image-detection-poc/venv/lib/python3.10/site-packages/sympy/unify/rewrite.py /sz3rewriterule..rewrite_rl..)rrxreplacer isinstancerr)expr assumptionsexpr2assume conditionsourcetargetrr r rewrite_rl,s  zrewriterule..rewrite_rlN)Tr)rrrrrrrrr rewriterules$ r)rNN) __doc__sympy.core.exprrsympy.assumptionsrsympy.strategies.toolsrsympy.unify.usympyrrrrrrrs
