Question

实施GuessNumber游戏。在这个游戏中，电脑 - 想想0-50范围内的随机数。（提示：使用随机模块。） - 反复提示用户猜出神秘数字。 - 如果猜测正确，请祝贺用户获胜。如果猜测不正确，请让用户知道猜测是太高还是太低。 - 经过5次错误的猜测后，告诉用户正确的答案。

以下是正确输入和输出的示例。

I’m thinking of a number in the range 0-50. You have five tries to
guess it.
Guess 1? 32
32 is too high
Guess 2? 18
18 is too low
Guess 3? 24
You are right! I was thinking of 24!

这是我到目前为止所得到的：

import random

randomNumber = random.randrange(0,50)
print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
guessed = False

while guessed == False:
    userInput = int(input("Guess 1?"))
    if userInput == randomNumber:
        guessed = True
        print("You are right! I was thinking of" + randomNumber + "!")
    elif userInput>randomNumber:
        print(randomNumber + "is too high.")
    elif userInput < randomNumber:
        print(randomNumber + "is too low.")
    elif userInput > 5:
        print("Your guess is incorrect. The right answer is" + randomNumber)

print("End of program")

我一直在收到语法错误，当用户输入错误的答案时，我不知道如何将猜测增加一，例如，猜猜1？，猜猜2？，猜猜3？猜猜4？，猜5？等等......

Answer 1

由于你知道你经历循环的次数，并想要计算它们，所以使用for循环来控制那个部分。

for guess_num in range(1, 6):
    userInput = int(input("Guess " + str(guess_num) + "?"))
    if userInput == randomNumber:
        # insert "winner" logic here
        break
    # insert "still didn't guess it" logic here

你看到它是如何运作的吗？

您忘记缩进属于while循环的代码。此外，您希望跟踪您猜测的次数，使用建议的变量或循环。此外，在给出提示时，您可能想要打印玩家猜测的数字，而不是实际的数字。如，

import random

randomNumber = random.randrange(0,50)
print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
guessed = False
count = 0

while guessed is False and count < 5:
    userInput = int(input("Guess 1?"))
    count += 1
    if userInput == randomNumber:
        guessed = True
        print("You are right! I was thinking of" + randomNumber + "!")
    elif userInput > randomNumber:
        print(str(userInput) + " is too high.")
    elif userInput < randomNumber:
        print(str(userInput) + " is too low.")
    if count == 5:
        print("Your guess is incorrect. The right answer is" + str(randomNumber))
        print("End of program")

Answer 3

您正面临语法错误，因为您正在尝试向字符串添加整数。这是不可能的。要执行您想要的操作，您需要在每个打印语句中转换randomNumber。

import random

randomNumber = random.randrange(0,50)

print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
guessed = False

while guessed == False:
    userInput = int(input("Guess 1?"))
    if userInput == randomNumber:
        guessed = True
        print("You are right! I was thinking of" + str(randomNumber) + "!")
    elif userInput>randomNumber:
        print(str(randomNumber) + "is too high.")
    elif userInput < randomNumber:
        print(str(randomNumber) + "is too low.")
    elif userInput > 5:
        print("Your guess is incorrect. The right answer is" + randomNumber)

print("End of program")
