python - 为什么 Spyder 不会运行或调试我的代码？
问题描述
我是在 Spyder 上使用 Python 3.7 的初学者程序员，当我运行我的代码时，它会打开一个 system32 命令提示符，然后立即关闭。什么都没发生。当我尝试按下调试按钮时也会发生同样的事情。我将在这里粘贴我的代码。编辑：感谢 Oliverm，我已经更新了代码，但代码仍然无法启动。

解决方案
关于：
“缩进中制表符的使用不一致。”
您需要确保使用制表符或简单空格作为空白字符。将两者混合将导致上述错误。您可以将您的 spyder 配置为在按 Tab 时使用例如 4 个意图。
根据Spyder Python indentation try的回答
在 Spyder v3.0.0 中，转到 Source --> Fix Indentation。这对我有用。
在开始调试之前，您需要修复语法错误。
要使用调试器，您需要在代码中或在启动调试器时定义断点。Spyder 在 ipython 控制台中使用 ipdb 调试器。查看有关调试的 spyder 文档： https ://docs.spyder-ide.org/debugging.html
从他们的文档中，您可以使用以下选项来设置断点：
为在编辑器中打开的文件中的任何行设置和清除正常断点和条件断点的多种方法。
- 通过从“调试”菜单中选择相应的选项。
- 通过按可配置的键盘快捷键（默认为 F12 正常，或 Shift-F12 为条件断点）。
- 通过双击打开文件中行号的左侧。
- 在代码中使用 ipdb.set_trace() 语句（在 import pdb 之后）。
- 以交互方式，在 ipdb 会话中使用 b 命令。
查看例如：https ://realpython.com/python-debugging-pdb/以获取快速调试教程。
我已经在下面的代码中快速修复了您的语法问题。此外，如果输入通过，用于选择播放或不播放的 if 子句更改为正确评估为 True 或 False。
现在应该可以进行调试了。为了让您开始，我在脚本的开头导入了 ipdb，并在 greetings 函数中设置了一个断点（第 29 行）。
关于关闭窗口的问题，请检查工具 -> 首选项 -> 运行 -> 控制台中的设置。如果您希望程序在 Spyder 的当前 iPython 控制台中执行，请选择“在当前控制台中执行”。
