I'm working on a simple file processing utility, and I encountered a
weird error. If I try to get the first element of a list I'm
splitting from a string, I get an error:
key = string.split()[0]
Error!
However, I can slice the list like normal, but that gives me a
one-element-long list:
key = string.split()[:1]
Success!
Finally, the operation works perfectly if I initialize the list
beforehand:
list = string.split()
key = list[0]
Success!
Why does this happen?
==========================
Take a look at the split() command.
I think you will find you need one var on the left side for each piece
on the right.
Given that he's immediately indexing the split results, that's irrelevant.
There's no point in even guessing with out the traceback.
"...the first element of a list..."
"key = string.split()[0]"
if the list is a list of tuples the error message is correct.
same for a list of key:value pairs
he will need one var on left for each piece of [0]
k,v= list.split(key:value) ??!!
