Python代码在Pycharm中不起作用，但在Jupiter Notebook中执行良好

Question

我有以下代码：

from random import randint
pyPicInteger = randint(1,100);

print("Hello Genius, Lets introduce this game to you!\n\nThe game will get the lucky number, you just need to GUESS the luck number.\n\nThe winner will be who guess the number in the less attempts!!!")

print(pyPicInteger)

attempts=[0]

while True:
    playerInput = int(input("Guess the number: "))
    attempts.append(playerInput)
    if playerInput < 1 or playerInput > 100:
        print("Your guess is out of bound...Enter the value between 1 and 100!")
        continue
    if playerInput == pyPicInteger:
        print("YOU ARE THE WINNER NOW!!! YOU HAVE ACHEIVED IN {} ATTEMPTS".format(len(attempts)))
        break

    if attempts[-2]:
        if abs(pyPicInteger - playerInput) < abs(pyPicInteger-attempts[-2]):
            print("WARMER!")
        else:
            print("COLDER!")
    else:
        if abs(pyPicInteger-playerInput) <= 10:
            print("WARM!")
        else:
            print("COLD!")    

使用PyCharm运行它时，出现以下错误：

Answer 1

正如@ 101所说，看来您正在Pycharm和Jupyter中运行不同版本的Python。在PyCharm中，您可以通过以下方式进行更改：

1. 在“设置/首选项”对话框中，单击“项目解释器”。

1. 点击齿轮图标，然后选择添加...。py添加解释器 将打开“添加Python解释器”对话框。

1. 从下拉列表中选择基本解释器，或单击browserButton并在文件系统中找到基本解释器。您应该将路径提供给使用jupyter的解释器。

您可能会出现此错误的另一个原因是，您只是在程序期望输入数字时输入空字符串，因此请避免这样做，因为int('')会给您您报告的错误相同：

  

ValueError：以10为底的int（）无效文字：

Answer 2

您正在输入一个空字符串，如消息所示。在转换输入之前，请先对其进行验证。像这样：

answer = input("Guess the number: ")
if not answer.isdigit(): continue
playerInput = int(answer)

这应该可以解决问题。
