ValueError: Too Many Values to Unpack Aptana Studio 3

问题

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?

回答1:

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.

回答2:

in the script window, right click, ShowIn > Terminal. It will open a terminal window in Aptana. Then type, python 'your script'.py That will run in way you want I think; Rather with the visual you want.
