这是Spyder附带的一个iPython头像。当从几秒后复制/粘贴随机代码片段来测试以发现非常奇怪的行为时，我已经陷入了这种情况 - 在iPython控制台中定义的变量也将无限期地放在脚本的全局名称空间中。

This is a bit of an iPython headshot that comes with Spyder. I've fallen foul of this when copy/pasting random bits of code from SO to test only to find really odd behaviour several days later - variables defined in the iPython console will also be in the script's global namespace indefinitely.

您可以执行以下两项操作：

There's two things you can do:

1. 内核硬启动（ ctrl + 。）


2. 后续这个功能请求线程，现在可以在每次运行脚本时自动清除名称空间。

1. A hard restart of the Kernel (ctrl + .)
2. Follow up on this feature request thread where it's now possible to clear the namespace automatically every time you run a script.
