I have to use an if loop in my program. I am checking the irreducibility of a collection of polynomials. If f(x) is a reducible polynomial, then I want to find its factor. This is my code
v=f.is_irreducible()
if (v==0) f.factor()
But I am getting a syntax error. Can someone help me ?
You need a colon:
if (v==0): f.factor()
I would actually write this as:
if not f.is_irreducible():
f.factor()
Your assignment of v=f.is_irreducible() doesn't seem to be necessary unless you want to use v several times later. If so, you could do
v = f.is_irreducible()
if not v: # better than checking v == 0
f.factor()
