Thanks Eric and Alan i did that with while loop. I donno i was getting an
error while using a for loop for subindexing. Here is what i did
i=0
selectCols=0
arr2=[]
while i<rows:
selectCols=grid[i][colID]
i+=1
arr2.append(selectCols)
print "col",colID,"values :",arr2
----->colID is the value of the requested column to print. which remains the
same throughout the iteration of while.
