ValueError:太多的值无法解压 Aptana Studio 3 [英] ValueError: Too Many Values to Unpack Aptana Studio 3

问题描述

我正在学习 learnpythonthehardway.org 上的练习 13.我应该运行这个代码:

from sys import argv脚本，第一，第二，第三 = argvprint "脚本被调用:", 脚本打印您的第一个变量是:"，首先打印您的第二个变量是:"，第二个打印您的第三个变量是:"，第三个

然后在命令行输入python ex13.py first 2nd 3rd"，应该输出:

脚本调用:ex13.py你的第一个变量是:第一你的第二个变量是:2nd你的第三个变量是:3rd

但是，我在 Vista 上使用 Aptana Studio 3 并且我得到了ValueError:要解压的值太多"错误.

我是 Python 和 Aptana 的新手，所以如何在此处输入单独的参数?

解决方案

这是因为 len(argv) 可能大于 4:

<预><代码>>>>w,x,y,z=[1,2,3,4,5]回溯(最近一次调用最后一次):文件<stdin>"，第 1 行，在 <module> 中ValueError:解包的值太多

尝试打印 argv 以查看 argv 实际包含的内容.

I am working on exercise 13 from learnpythonthehardway.org. I should run this code:

from sys import argv
script, first, second, third = argv

print "The script is called:", script
print "Your first variable is:", first
print "Your second variable is:", second
print "Your third variable is:", third

Then enter "python ex13.py first 2nd 3rd" on command line and should output:

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

However, I am using Aptana Studio 3 on Vista and I get the "ValueError: too many values to unpack" error.

I am new to Python and Aptana so how can I enter the separate arguments here?

解决方案

It's because len(argv) might be greater than 4:

>>> w,x,y,z=[1,2,3,4,5]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: too many values to unpack

Try printing argv to see what argv actually contains.
