I'm really confused by what is happening here. If I use zip(), I
can't update individual dictionary elements like I usually do. It
updates all of the dictionary elements. It's hard to explain, so here
is some output from an interactive session:
In [52]: header=['a','b','c','d']
In [53]:
quick update,
#change this line:
for (k,v) in zip(header,[[]]*len(header)):
#to this line:
for (k,v) in zip(header,[[],[],[],[]]):
and it works as expected. Something about the [[]]*len(header) is
causing the weird behavior. I'm probably using it wrong, but if
anyone can explain why that would

Thanks! That certainly explains it. This works as expected.
columnMap={}
for (k,v) in zip(header,[[] for i in range(len(header))]):
#print %s,%s%(k,v)
columnMap[k] = v
columnMap['a'].append('test')
