Comment #5 on issue 3667 by smi...@gmail.com: getting consistent output
from solve until a Solution class is available
http://code.google.com/p/sympy/issues/detail?id=3667
Another inconsistent output is that it can return a generator:
radsimp(1/(root(2,3)+root(2,5)))
1/(2**(1/5) + 2**(1/3))
minpoly(_)
40*_x**15 + 240*_x**14 + 240*_x**13 - 80*_x**12 + 1080*_x**11 - 12*_x**10 +
80*_
x**9 + 360*_x**8 - 40*_x**6 + 6*_x**5 + 10*_x**3 - 1
eq=_
sol=solve(eq,check=0)
len(sol)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: object of type 'generator' has no len()
and this is not fixed by requesting a dict output
sol=solve(eq,check=0,dict=True)
Traceback (most recent call last):
