The documentation says: doit(***hints*) <http://docs.sympy.org/0.7.1/_modules/sympy/core/basic.html#Basic.doit>
Evaluate objects that are not evaluated by default like limits, integrals, sums and products. All objects of this kind will be evaluated recursively, unless *some species were excluded* via ‘hints’ or unless the ‘deep’ hint was set to ‘False’. http://docs.sympy.org/0.7.1/modules/core.html#sympy.core.basic.Basic.doit What is the correct way to exclude things from being processed in doit? Say in the expressions below expr = ( Sum(k, (k, 0, 10)) + Integral(x, (x, 0, 2) ).doit() I want doit to evaluate only the Integral and not the Sum. So that the result is equivalent to expr = ( Sum(k, (k, 0, 10)) + Integral(x, (x, 0, 2).doit() ) Is there a way to do that? Trying the obvious expr.doit(Sum=False) does not work.
