I'm trying to write a program in Python that flips a coin and returns the longest series of heads and tails. It asks the user how many times to flip the coin. For some reason my program isn't running and I cant figure out why. I don't know why it isn't asking the user for the "number of flips" and "as a character string" for example.
import random
def flip():
flipValue = random.randint(1,2)
if flipValue == 1:
side = "Heads"
else:
side = "Tails"
return side
def nStreak():
number = int(input("Number of flips: "))
chars = int(input("As a character string: "))
series = 0
heads = 0
tails = 0
longest_h = 0
longest_t = 0
while series != number:
side = flip()
series += 1
if side == "Heads":
heads += 1
tails = 0
if heads == chars:
longest_h += 1
heads = 0
if side == "Tails":
tails += 1
heads = 0
if tails == chars:
longest_t += 1
tails = 0
print("Number of heads streaks: ", longest_h)
print("Number of tails streaks: ", longest_t)
When I run it I get nothing.
You need to call the function at the last line.
nStreak()
Or else it won't execute the code.
在脚本的底部,添加没有标识的nStreak()
