不允许我在函数和int

Question

猜测游戏

from random import randint
from time import sleep

def get_user_guess():
  guess = int(input('What is your guess: '))
  return guess

def roll_dice(number_of_sides):
  first_roll = randint(1, number_of_sides)
  second_roll = randint(1, number_of_sides)
  max_val = number_of_sides * 2
  print ("The maximum value you can roll is %d" % max_val)
  get_user_guess()
  if get_user_guess > 13:
    print ("invalid guess, please try again")
  else:
    print ("Rolling...")
    sleep(2)
    print ("%d" % first_roll)
    sleep(1)
    print ("%d" % second_roll)
    sleep(1) 
    total_roll = first_roll + second_roll
    print ("%d" % total_roll)
    print ("Result...")
    sleep(1)
    if get_user_guess == total_roll:
        print ("Congratulations, you've won!")
    else:
        print ("sorry sucker, you lose!")
roll_dice(6)

这是代码。我在python 2中制作了一个正在运行的版本，但将其翻译为python 3一直让人头疼。我已经定义了get_user_guess，其中guess =一个int。但是，在roll_dice部分中，我调用上一个函数及其答案之后，我得到了错误消息。

Answer 1

这不是访问函数返回值的方式。您应该将返回值分配给新名称，然后在以下比较中使用它。

guess = get_user_guess()
if guess > 13:
    print("invalid guess")
else:
    ...
    if guess == total_roll:
        print("Congratulations")
    else:
        print("sorry")

Answer 2

因此，这看起来像是一个小逻辑错误，也有语法错误。首先是语法错误。您并没有真正通过以下操作初始化或调用比较中的函数：

if get_user_guess > 12

而不是：

if get_user_guess() > 12

因此没有什么可与“>”运算符进行比较的。

第二，看到您正试图将变量重新用于下一个比较，您也需要存储它，否则它将再次提示用户输入新值。请注意，第13,14和28行的更改将解决此问题：

from random import randint
from time import sleep

def get_user_guess():
  guess = int(input('What is your guess: '))
  return guess

def roll_dice(number_of_sides):
  first_roll = randint(1, number_of_sides)
  second_roll = randint(1, number_of_sides)
  max_val = number_of_sides * 2
  print ("The maximum value you can roll is %d" % max_val)
  guess = get_user_guess()
  if guess > 13:
    print ("invalid guess, please try again")
  else:
    print ("Rolling...")
    sleep(2)
    print ("%d" % first_roll)
    sleep(1)
    print ("%d" % second_roll)
    sleep(1) 
    total_roll = first_roll + second_roll
    print ("%d" % total_roll)
    print ("Result...")
    sleep(1)
    if get_user_guess == total_roll:
        print ("Congratulations, you've won!")
    else:
        print ("sorry sucker, you lose!")
roll_dice(6)
