I want to compare zenith, a floating point number, with the current
y value?
I thought the current y value could be retrieved by Projectile.getY.
Projectile.getY is a reference to the getY method of the Projectile
class.

There are 2 ways to get the ypos value one is cball.ypos and another is
call.getY() both will give u the current ypos.

Andrew,
For starters you have some errors in the way you are trying to access
methods from within a class instances. For example in your code in line 7
and 8,
def main():
angle, vel, h0, time = getInputs()
cball = Projectile(angle, vel, h0)
zenith = 0.0
while cball.getY() =
