 Don’t use \doifmode{…}{…} etc. with buffers or environments which rely on a 
 buffer because you disable the function to keep end of lines in the input.
 
 What you have to do in this case is to use the \startmode or \startnotmode 
 commands.

Thanks Wolfgang and Aditya.
This behaviour of doifmode is not documented in the wiki. Can anyone could add 
it

it is unrelated to doifmode but a general tex property: if you pass 
arguments the catcodes are frozen


\startmode[foo]

\stopmode

can be tried as alternative as that one doesn't pick up arguments

\starttext

\startmode[solucions]

\starttextrule{Solucions}

\startpython

\stoppython

\stoptextrule

\stopmode

\stoptext


Another option is (untested):

\defineexternalfilter
  [python]
  [
filtercommand={...},
before={\starttextrule{Solutions}},
after={\stoptextrule},
  ]

\startmode[solutions]
\setupexternalfilter[python][state=stop, read=no]
\stopmode

\starttext

\startpython
...
\stoppython
\stoptext

BTW, you can simplify your setup using:

\startbuffer[sympy]
from sympy.solvers import solve
from sympy import Symbol
from sympy import Eq

x = Symbol('x')
\stopbuffer

\defineexternalfilter
  [python]
  [
filtercommand={...},
bufferbefore={sympy},
  ]

\starttext
\startpython
print(solve(Eq(3*x + 2, 35), x))
\stoppython
\stoptext
