Calculating and plotting the argument of a transfer function

My transfer function is the following.

$$ H(\omega) = \frac{2000}{201\cdot10^3 + 109 10j\omega - 0.132\omega} $$

I have trouble calculating the argument. Is it the following?

$$ \lvert H \rvert = \arg \left( \frac{2000}{201\cdot10^3 + 109 10j\omega - 0.132\omega} \right)\\\lvert H \rvert= \arg(2000) - \arg\left(201\cdot10^3 + 109 10j\omega - 0.132\omega\right)\\\lvert H \rvert= \arctan (2000) - \arctan \left(201\cdot10^3 + 109 10j\omega - 0.132\omega\right)$$

If so, how can I reduce it so I can plot it in Python?
