Does anyone have a Sage hold frunction? Look at the code below
---------------------------------
def LikeSimplify1a(ex1,ex2,ex3,ex4):
eq1=str(ex1)+"+"+"("+str(ex2)+")"+"+"+"("+str(ex3)+")"+"+"+"("+str
(ex4)+")"
n1=SR(ex1);n2=SR(ex2);n3=SR(ex3);n4=SR(ex4)
eq2=maxima.ratsimp(n1+n2+n3+n4)
return eq1,eq2
----------------------------------------
Input
----------------------------------------
a1=LikeSimplify1a('-2*(-x-2*x^2-x)','-sqrt(12)-x','-2*(4-10)','10');a1
[0];a1[1];#a1[2]
-------------------------------------------------------
Output
-----------------------------------------------------------
'-2*(-x-2*x^2-x)+(-sqrt(12)-x)+(-2*(4-10))+(10)'
4*x^2+3*x-2*sqrt(3)+22
------------------------------------------------------------
This is in the notebook and is about what I want. When I use it on my
server the -sqrt(12) becomes -2sqrt(3). I don't want this. Can
anyone help me with a hold function that works in a Python script?
Thanx
