solution set of sin(x)=0 is not simplified, presented as union of two sets

1

The following sets up an equation $sin(x)=0$ `eq = sympy.Eq(sympy.sin(x), 0)` The following asks simpy's solveset solver to solve this equation. `sympy.solveset(eq, x)` The result is: `{2nπ∣n∈Z}∪{2nπ+π∣n∈Z}` This could be...
