提问by Bazman
I'm running the code below in Spyder. I have typed it in a py file and simply hit the run button.
我在 Spyder 中运行下面的代码。我已经将它输入到一个 py 文件中，然后只需点击运行按钮。
When I try to run it I get the error:
当我尝试运行它时，出现错误：
ValueError: need more than 1 value to unpack

As shown here you are meant to give the inputs for the argv variable before running the program but I don't know how to do this is spyder?
如此处所示，您打算在运行程序之前为 argv 变量提供输入，但我不知道如何做到这一点是 spyder？

问：当我运行它时，我得到
ValueError: need more than 1 value to unpack.请记住，一项重要的技能是关注细节。如果您查看您应该看到的内容部分，您会看到我在命令行上运行带有参数的脚本。你应该完全复制我如何运行它。
Make sure you run the command:

$ python ex13.py first 2nd 3rd
$ python ex13.py first 2nd 3rd
>> The script is called: ex13.py >> Your first variable is: first >> Your second variable is: 2nd >> Your third variable is: 3rd

on the dialog that appears after that, and finally enter the command line arguments you want to pass to the script, which in this case could be
在之后出现的对话框中，最后输入要传递给脚本的命令行参数，在这种情况下可以是

In addition to configuring in the Run->Configureas explained in other answers,
you can use "runfile" directly from the console.
除了Run->Configure按照其他答案中的说明进行配置外，您还可以直接从控制台使用“runfile”。
Run the following:
运行以下命令：
runfile('ex13.py', args='first second third')
