I am trying to convert "complex_root_of" expressions to algebraic numbers
(elements in the field QQbar). However, I get a "ValueError" with the
message "to many values to unpack".
A minimal example would be:
from sage.all import *
from sympy import sympify
exp1 = sympify("CRootOf(x**2 + 1, 0)")._sage_()
exp2 = sympify("CRootOf(x**2 + 1, 1)")._sage_()
print(exp1)
print(exp2)
exp1 = QQbar(exp1)
exp2 = QQbar(exp2)
print(exp1)
print(exp2)
The context I am working in is: I have a tool that is currently written in
python and sympy. I am trying to use the output of that tool to do some
further computation using sage, and the output of the first tool may
contain CRootOf expressions.
