Hi, I'd like to be able to save number fields with embeddings as text
strings, so that they can be instantiated at a later date, as well as being
human readable. So, I'm trying to store the command used to create such a
field, and use sage_eval on it.
sage: x = polygen(QQ)
sage: K.<x> = NumberField(x^2 + x - 1/2, embedding=0.366)
The above works, but the following gives an error:
sage: K.<x> = sage_eval('NumberField(x^2 + x - 1/2, embedding=0.366)',
locals={'x': x})
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/Users/ev/Projects/flagmatic/<ipython console> in <module>()
TypeError: sage_eval() got an unexpected keyword argument 'names'
Does anyone know how to fix this? Thanks!
