python3.5：猜谜立方根游戏作为输出返回no

Question

我已经找到了关于这个问题的其他答案，但是在我的程序中实现这个解决方案时遇到了困难（对于Python来说还是很新的）。以下是我目前掌握的情况：

# Purpose: 'guess' randomly selects a number between 0 and 100 (including those
# numbers) and calculate the cube of that number. It also prompts the user to 
# guess the cube root of the cubed number, displaying 'Correct!' if correct, and
# asking the user if they would like to try again if incorrect.

def guess():
    import random
    rand = random.randint (0, 100)
    cubed = rand*rand*rand

    # Forming the input question
    string = "What is the cube root of"
    cubed = str(cubed)
    qmark = "?"
    question = print(string, cubed + qmark)

    user = int(input(question))
    while (user == rand):
        print ("\nCorrect!")
        user = input("\n\tWould you like to try again?").lower()


    if (user != rand):
        print ("\tIncorrect!, the cube root of", cubed, "is", rand)

这应该是输出的样子：

guess()

What is the cube root of 64000? 56
            Incorrect, the cube root of 64000 is 40

            Would you like to try again? y

What is the cube root of 216? 6
        Correct!

        Would you like to try again? n

Goodbye

Answer 1

这可能有助于：

def guess():
    import random
    rand = random.randint (0, 100)
    cubed = rand*rand*rand

    # Forming the input question
    question = "What is the cube root of {cubed} ?".format(cubed=cubed)

    user = int(input(question))
    if user == rand:
        print ("\nCorrect!")

    else:
        print ("\tIncorrect!, the cube root of", cubed, "is", rand)

choice = 'y'
while choice == 'y':
  guess()
  choice = input("Would you like to play again ?").lower()
else:
  print("Goodbye")

您将print函数（即None）的返回值存储在question中，然后将question传递给正在打印它的input函数

Answer 2

这是一个非常好的函数开始尝试！有两件事需要解决：

1）问题变量中不应包含打印。在input（）中放入一个变量将为您打印它。这样会更好：

question = string+" "+cubed+qmark

2）底部部分不太正确。也许你想要这样的东西？最后一行再次调用整个函数-这称为“递归”。你知道吗

user = int(input(question))
if (user == rand):
    print ("\nCorrect!")
elif (user != rand):
    print ("\tIncorrect!, the cube root of", cubed, "is", rand)
user = input("\n\tWould you like to try again?").lower()
if user == "y":
    guess()

总而言之，这里是最后的代码：

# Purpose: 'guess' randomly selects a number between 0 and 100 (including those
# numbers) and calculate the cube of that number. It also prompts the user to 
# guess the cube root of the cubed number, displaying 'Correct!' if correct, and
# asking the user if they would like to try again if incorrect.

def guess():
    import random
    rand = random.randint (0, 100)
    cubed = rand*rand*rand

    # Forming the input question
    string = "What is the cube root of"
    cubed = str(cubed)
    qmark = "?"
    question = string+" "+cubed+qmark #################### Remove print here. Input will do it for you.

    user = int(input(question))
    if (user == rand):
        print ("\nCorrect!")
    elif (user != rand):
        print ("\tIncorrect!, the cube root of", cubed, "is", rand)
    user = input("\n\tWould you like to try again?").lower()
    if user == "y":
        guess()
    else:
        print("Goodbye")

guess()

我最近才开始编程，这是我第一次帮助别人！你知道吗

编辑：根据注释中的建议，下面是一种不使用递归的方法，将所有内容放入“While True循环”（也称为forever循环）：

def guess():
    while True:
        import random
        rand = random.randint (0, 100)
        cubed = rand*rand*rand

        # Forming the input question
        string = "What is the cube root of"
        cubed = str(cubed)
        qmark = "?"
        question = string+" "+cubed+qmark #################### Remove print here. Input will do it for you.

        user = int(input(question))
        if (user == rand):
            print ("\nCorrect!")
        elif (user != rand):
            print ("\tIncorrect!, the cube root of", cubed, "is", rand)
        user = input("\n\tWould you like to try again?").lower()
        if user != "y":
            print("Goodbye")
            break
