Hi!
I don’t know if Sympy has a method to do it. The truth is I don’t know much.
Using my limited knowledge I wrote a function to do it. I’m sure that it can be
improve a lot but it works:
- - - - -
def newpoly(coefs):
p = ""
for i in range(len(coefs)):
p += str(coefs[i]) + '*x**' + str(len(coefs)-i-1) + '+'
p = p[:-1]
return sympify(p)
newpoly([4,8,3])
- - - - -
