用的Pythoncharam, 代码跟老师的一样，为什么抱语法错误啊？
import random
num = random.randint(0, 100)
while True:
try:
guess = int(raw_input('Enter 1~100:'))
except ValueError:
print('Enter 1 ~ 100')
continue
if guess > num:
print('guess Bigger:' , guess)
elif guess < num:
print('guess Smaller:' , guess)
elif:
print('Guess OK, Game Over')
break
