Valueerror need more than 1 value to unpack

Question

Problem:

I am getting an error while I am trying to run a python program. Please have a look at it and give me a solution if possible. I am trying to figure the problem but I fail to do so.

from sys import argv
script, usr_name =argv
prompt = '>'
print "Hello %s, I'm the %s script." % (usr_name, script)

Here is the error, “valueerror need more than 1 value to unpack”

Traceback (most recent call last):  
script, usr_name =argv  
ValueError: need more than 1 value to unpack

Thanks.

Answer 1

Probably you didn't provide an argument on the command line. In that case, sys.argv only contains one value, but it would have to have two in order to provide values for both usr_name and scrip

.Try something like this below:

script, one, two = argv
print "My file is:", script
print "My first entry is:", one
print "My second entry is:", two

I hope you get the point. So, fix the error this way and try to run the program again. Let me know if it works or not. If works, leave a kudos.
You are welcome.
