A list contains several NoneType elements. To skip the NoneType, 

for item in list :
    if item is not None :
        fp.write(item + '\n')

#OR

for item in list : 
    try :
        fp.write(item + '\n')
    except :
        pass

Which one is better and why？

As a general rule of thumb, you should not really be using the try: except: pattern for control flow if you can help it. There is some overhead involved with raising an exception that is unnecessary in this context. Hope this helps.
