猜字游戏输出结果异常？Python萌新。求解决方案

Question

import random
secret = random.randint(1, 99)
guess = 0
tries = 0
print("AHOY! I'm the Dread Pirate Roberts, and I have a secret!")
print("It is a number from 1 to 99. I'll give you 6 tries.")
while guess != secret and tries < 6:
guess = input("What's yer guess?")
if guess < secret:
print("Too low,ye scurvy dog!")
elif guess > secret:
print("Too high, landlubber!")

tries = tries + 1

if guess == secret:
print("Avast! Ye got it! Found my secret, ye did!")
else:
print("NO more guess! Better luck next time,matey!")
print("The secret number was",secret)

输出结果：

AHOY! I'm the Dread Pirate Roberts, and I have a secret!
It is a number from 1 to 99. I'll give you 6 tries.
What's yer guess?50
