for (key, value) in wordFreq2:
ValueError: need more than 1 value to unpack

this is a sample of my data

['with', 3, 'which', 1, 'were', 2, 'well', 1, 'water', 1, 'was', 4,
'two', 1, 'to', 2, 'through', 1, 'thlabour', 1, 'these', 1, 'theat', 1,
'the', 8, 'tetanus', 1, 'started', 1, 'size', 1, 'scent', 1,
'respectively', 1, 'received', 1, 'problems', 2, 'prince', 1,
'pregnancy', 1, 'poured', 1, 'peace', 1, 'pains', 1, 'painless', 1,
'out', 1, 'of', 1, 'noseat', 1, 'nose', 2, 'no', 2, 'maternity', 1,
'malformation', 1, 'made', 1, 'lower', 1, 'labour/delivery', 2,
'kintampo', 1, 'into', 1, 'injections', 1, 'in', 3, 'i', 2, 'hospital',
1, 'home', 1, 'him', 1, 'having', 1, 'had', 2, 'green', 1, 'gave', 1,
'flowing', 2, 'encountered', 1, 'eleven', 1, 'during', 3, 'district', 1,
'difficulty', 1, 'cord', 1, 'consecutive', 1, 'colour', 1, 'cleared', 1,
'child', 1, 'checkups', 1, 'came', 1, 'but', 2, 'breathing', 2,
'breath', 1, 'blood', 2, 'bleeding', 1, 'birth', 4, 'before', 1, 'bad',
1, 'average', 1, 'at', 2, 'assist', 1, 'artificial', 1, 'around', 2,
'antenatal', 1, 'and', 5, 'an', 1, 'ambrical', 1, 'air', 1, 'abdominal',
1, '600am', 1, '100pm', 1, '', 3, 'other']

What I would like to do is to pad the last value 'other' with a default
so I can iterate sucessfully

my desired ouput is the format below in a text file.
with 3
which 3
were 2
..
.
.
other

The line:

for (key, value) in wordFreq2:

attempts to iterate through the list wordFreq2, where each item in the
list is a _pair_ of values.

However, what you have is a list of _single_ values, alternating string
and number.

That's why it's complaining that it can't unpack.
for i in range(0, len(x), 2):
    print x[i-1], x[i]
