python noob help

[toyko]

So yeah, I have this assignment for my computer science class,
http://pages.cpsc.ucalgary.ca/~boyd/231/as1.pdf so far this is what I have
wrote, any suggestions cause I am stuck!


xc, yc = input()
r = input()
x1, y1 = input()
x2, y2 = input()

a = (x2 - x1)**2 + (y2 - y1)**2
b = 2((x1 - xc)(x2 - x1) + (y1 - yc)(y2 - y1))
c = (x1 - xc)**2 + (y1 - yc)**2 - r**2

discrim = (b * b - 4 * a * c) ** 0.5
Q = (-b + discrim) / (2 * a)
Q = (-b - discrim) / (2 * a)

x = (1-Q) * x1 + Qx2
y = (1-Q) * y1 + Qx2

# CIRCLE
print "circle", xc, yc, r

# LINE
print "line", x1, y1, x2, y2

Learn Python and actually *think* about the problem and a solution. We
are not going to do your homework for you. You have to show a little
effort. So far you have just tried to copy the formulas from the
assignment to Python code -- and failed because there are runtime
errors. So you didn't even bother to test what you have so far before
crying for help.

small hint :
"(5)(2)" don't work, use "5*2"
same for "Qx2", use "Q*2"
