This won't work.
>>> fob = []
>>> gab = ["fooBar","Baz","aBBa"]
>>> for line in gab:
... print line,
... x = line.replace('B', 'X')
... print x
... fob.append(x)
... print fob[line]
...
fooBar fooXar
Traceback (most recent call last):
File "<interactive input>", line 6, in ?

>ValueError: unpack list of wrong size
What should I do?
Catch the exception -
try:
(temp11, temp22, pyra11, pyra22, voltage11, current11) = y.split('\t')
except ValueError:
print "Line:", y
print len(y.split('\t')), "items found"
And see what's going wrong. You get a ValueError like that one like so -
>>> x = ["1,2,3",
"4,5,6",
"7,8"]
>>> for af in x:
... (a,b,c) = af.split(',')
... print a,b,c
...
1 2 3
4 5 6
Traceback (most recent call last):
File "<interactive input>", line 2, in ?
ValueError: unpack list of wrong size
See, it's trying to get 3 items from each split, but the last one only
gives 2 items.
So, print the offending line, I'm guessing it's a blank "\n" or "\t" line.

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
