Let $p$ be a prime and consider the field $\mathbb{Q}_p$ of $p$-adic numbers.
Question: What is an example for a finite extension $K/\mathbb{Q}_p$ which is neither unramified nor totally ramified? In case you know an explicit example, I am also curious to learn how to find the inertia degree, the ramification index and the maximal ideal of the valuation ring.
A general problem for me is that I am absolutely not able to find any literature containing some instructive examples and calculations in finite extensions $K$ of $\mathbb{Q}_p$, In case you know a good reference, this would be very helpful to me. Thanks!
