缅因州_脚本.py但是，当我试图导入它时，它返回错误，为什么？？你知道吗

忽略for word要求忽略for word要求忽略for word要求

Answer 1

文件mains_脚本.py必须在启动ipython的目录中。你知道吗

如果没有，您可以将其位置插入sys.path，以便解释器找到它

import sys
sys.path.insert(0, "path to mainss_script.py")

import mainss_script
mainss_script.mainss()

另外，%%writefile是将单元格内容写入文件的Jupyter magic alias命令。所以我猜你的代码是从某个Jupyter笔记本上复制过来的，运行包含这些行的单元格会在当前目录中创建mainss_script。你知道吗

如果没有该文件，请将那些代码行（不包括%%writefile行）粘贴到文件mains中_脚本.py在启动IPython的同一目录中。你知道吗

如果出于某种原因您确实希望保存维护_脚本.py在特定位置，然后您应该按照上面的说明将mainss\u脚本的路径添加到sys.path中，以便解释器找到它。在那之后，执行要导入并运行mainss()的行，事情就应该正常了。你知道吗
