如果您在正确猜测后不想让它停止，请删除中断，然后再次猜测：
Choose a number between 1 and 100. 80
That was too high of a guess. Try again.
Choose a number between 1 and 100. 60
That was too high of a guess. Try again.
Choose a number between 1 and 100. 40
That was too low of a guess. Try again.
Choose a number between 1 and 100. 50
That was too low of a guess. Try again.
Choose a number between 1 and 100. 55
That was too high of a guess. Try again.
Choose a number between 1 and 100. 53
That was too low of a guess. Try again.
Choose a number between 1 and 100. 54
You are correct, great job!
答案 1 :(得分：0)
你需要将随机数生成放在循环中，否则它只会反复测试相同的数字：
import random
while True:
number = random.randint(1,100)
pick = input("Choose a number between 1 and 100. ")
pick = int(pick)
if pick == number:
print("You are correct, great job! ")
while pick != number:
if pick > number:
print("That was too high of a guess. Try again. ")
break
elif pick < number:
print("That was too low of a guess. Try again. ")
break
请注意，我已将while True无限循环替换为正确性测试。
编辑：
但是，您可以进一步简化它：
import random
pick = 0
while True:
number = random.randint(1,100)
while pick != number:
pick = input("Choose a number between 1 and 100. ")
pick = int(pick)
if pick == number:
print("You are correct, great job! ")
break
elif pick > number:
print("That was too high of a guess. Try again. ")
else:
print("That was too low of a guess. Try again. ")
