Comment #3 on issue 1902 by smichr: 'has' method fails when argument is 'Symbol' or 'Wild'
http://code.google.com/p/sympy/issues/detail?id=1902
Perhaps you are confusing atoms() with has(). has() is suppose to look for patterns while atoms() will give sub-expressions of a given type (and it can get the type by
example):
var('x y z')
(x, y, z)
x.atoms(Symbol)
set([x])
(x+y).atoms(x) # class by example
set([x, y])
(x+y).has(x)
True
(x+y).has(z)
False (-1) Is there a reason to change the current behavior? -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
