Python - Find the ratio of the results

from random import random
from math import pi, sin

attempts = int(input("Enter the number of attempts to perform: "))
for i in range(1,attempts):
    ytail = 2.0*random()
    angle = pi*random()
    yhead = ytail + sin(angle)
    if yhead > 2.0:
        print ("hit")
    else:
        print ("not a hit")

Your program should prompt the user for the number of attempts to perform and print the ratio attempts/hits as a floating point number after all the attempts have completed.

How do I get the ratio of attempts/hits?

If you don't mind using numpy, here's an alternate solution:

import numpy as np
attempts = int(input("Enter the number of attempts to perform: "))
ytail = 2.0*np.random.rand(attempts)
angle = np.pi*np.random.rand(attempts)
yhead = ytail + np.sin(angle)
print(np.sum(yhead > 2.0)/attempts)

Store the number of hits in a variable, increment it when a hit occurs and print the ratio after iterating.

from random import random
from math import pi, sin

hits = 0
attempts = int(input("Enter the number of attempts to perform: "))
for i in range(0, attempts):
    ytail = 2.0 * random()
    angle = pi * random()
    yhead = ytail + sin(angle)

    if yhead > 2.0:
        hits += 1

print(hits / float(attempts))
