symplify boolean expression with comparison signs

Is there a library in python to simplify boolean expression with comparison expressions e.g.

from:

(a < 10 & a <= 10) | b

to:

(a < 10) | b

SymPy can do some simplification of this kind:

In [15]: from sympy import symbols

In [16]: a, b = symbols('a, b')

In [17]: condition = ((a < 10) & (a <= 10)) | b

In [18]: condition
Out[18]: b ∨ (a ≤ 10 ∧ a < 10)

In [19]: simplify(condition)
Out[19]: b ∨ a < 10

For more complicated problems you might need to tell SymPy how exactly to simplify the condition.
