import random

class GVCoin :
def __init__(self, seed):
random.seed(seed)
self._is_heads = True
self.heads = 0
self.flips = 0

def num_flips(self):
return self.flips

def num_heads(self):
return self.heads

def num_tails(self):
return self.flips - self.heads

def flip(self):
self.is_heads = random.randint(0, 1)

def consecutive_heads(gv_coin, goal):
# Type your code here

if __name__ == "__main__":
gv_coin = GVCoin(15)
num_heads = 5
num_flips = consecutive_heads(gv_coin, num_heads)
print('Total number of flips for 5 consecutive heads:', num_flips)

Given main() and GVCoin class, complete function consecutive_heads() that counts and returns the number of flips taken to achieve a
desired number of consecutive heads without a tails. Function consecutive_heads() has a GVCoin object and an integer representing the
desired number of consecutive heads without a tails as parameters.
Note: For testing purposes, a GVCoin object is created in the main() function using a pseudo-random number generator with a fixed seed
value. The program uses a seed value of 15 during development, but when submitted, a different seed value will be used for each test case.
Refer to the textbook section on random numbers to learn more about pseudo-random numbers.
Ex: If the GVCoin object is created with a seed value of 15 and the desired number of consecutive heads is 5, then the function
consecutive_heads() returns 16 and the program outputs:
Total number of flips for 5 consecutive heads: 16
