I have a vector of equations: using SymPy θ,ω,dθ,dω,b,c = symbols("θ,ω,\\dot{θ},\\dot{ω},b,c") f1 = Eq(dθ,ω) f2 = Eq(dω,-b*ω - c* sin(θ)) eqns = [f1;f2] out: \left[ \begin{array}{c} \dot{θ} = ω \\ \dot{ω} = -b*ω - c*sin(θ) \\ \end{array} \right] I want to return only the first side of the equal…

Did you try: [eqns[1].lhs; eqns[2].lhs] or better: [x.lhs for x in eqns]

Get left hand side of SymPy equations

Very enlightening.
