I changed the behaviour of _polynomial_list at file padic_ZZ_pX_CR_element.pyx, so that now:
A more detailed example that demonstrates the behaviour of _polynomial_list on zeros:
This behaviour is consistent with some other implementations of _polynomial_list, at files: CR_template.pxi, padic_ZZ_pX_CA_element.pyx, CA_template.pxi. In those files I also added doctests for the zero and O(w7) cases, to demonstrate their behaviour. |

Thanks! |
In SageMath 9.0, I do the following:
and then I try to get the padded coefficients of the polynomial yielding this "almost zero" element
I think the output of the above should be the same as below
