Description (last modified by )
We make the print representation of padic extensions shorter and clearer (in order to prepare #23218).
For example, the different outputs below from before this ticket:
sage: R.<a> = ZqCR(25, 40); R Unramified Extension in a defined by x^2 + 4*x + 2 with capped relative precision 40 over 5adic Ring sage: R.<a> = ZqCA(25, 40); R Unramified Extension in a defined by x^2 + 4*x + 2 with capped absolute precision 40 over 5adic Ring sage: R.<a> = ZqFM(25, 40); R Unramified Extension in a defined by x^2 + 4*x + 2 of fixed modulus 5^40 over 5adic Ring sage: R.<a> = ZqFP(25, 40); R Unramified Extension in a defined by x^2 + 4*x + 2 with floating precision 40 over 5adic Ring
become the same shorter outpout after this ticket:
sage: R.<a> = ZqCR(25, 40); R 5adic Unramified Extension Ring in a defined by x^2 + 4*x + 2 sage: R.<a> = ZqCA(25, 40); R 5adic Unramified Extension Ring in a defined by x^2 + 4*x + 2 sage: R.<a> = ZqFM(25, 40); R 5adic Unramified Extension Ring in a defined by x^2 + 4*x + 2 sage: R.<a> = ZqFP(25, 40); R 5adic Unramified Extension Ring in a defined by x^2 + 4*x + 2

All tests pass for me. We can wait for the patchbot to see if there are plugin errors.

648ea64  "base field" / "base ring"

If you agree, I give a positive review and open a new ticket for the pyflakes issues found by the patchbot.
