Solution 1:

You are pickling "DataBase" which is a class definition. You need to instantiate an object of class DataBase then pickle that.

objDataBase = DataBase()
objDataBase.Arrays.Data = etc....

filename='D:/results/file.lft'
file=open(filename,'w')
cPickle.dump(objDataBase, file, protocol=2)
file.close()
