当用户在玩猜谜游戏时按回车键时，如何打印字符串？

Question

我是一个初学者程序员，我创造了一个猜谜游戏，但我想纳入一个字符串，将打印时，用户按回车键，我已经尝试了这个，但它不起作用。（当用户按enter键时，返回错误“ValueError:invalid literal for int（），以10为基数）。你知道吗

如果用户不按enter键，只输入整数，程序就可以正常工作。你知道吗

highest = 12
lowest = 6
answer = 9


input("Press enter to play a guessing game")




guess = input("Guess a number from %d " %lowest + "to %d: " %highest)






while (int(guess) != answer) or guess == ():
    if int(guess) > answer:
        print ("Answer is lower")
    elif guess == ():
        print ("That's not valid") 




    else:
        print("Answer is higher")



guess = input("Guess again ")

print ("Correct!!") 

Answer 1

import random
a = int
b = int
c= int
def guessing():

      guess = int(input("guess an no between 1 to 10: "))
      c = random.randrange(1,11)
      print("answer is",c)
      if (guess == c):
            print("correct guess")
      elif(guess>c):
            print("higher")
      else:
            print("lower")

d=input("\n\n Y TO START \n n to exit\n")
if (d == "y" or d == "Y"):
      guessing()
elif(d =="n" or d == "N"):
      print("exit")
