In Python, when I run this code:
from sys import argv
script, user_name =argv
prompt = '>'
print "Hi %s, I'm the %s script." % (user_name, script)
I get this error:
Traceback (most recent call last):
script, user_name =argv
ValueError: need more than 1 value to unpack
What does that error mean?
youre getting ''ValueError: need more than 1 value to unpack'', because you only gave one value, the script (which is ex14.py in this case)
the problem is, that you forgot to add a name after you ran the .py file.
line 3 of your code is
script, user_name = argv
the script is ex14.py, you forgot to add a name after
so if your name was michael,so what you enter into the terminal should look something like:
> python ex14.py michael
make this change and the code runs perfectly
I assume you found this code on Exercise 14: Prompting And Passing.
Do the following:
script = '*some arguments*'
user_name = '*some arguments*'
and that works perfectly
