如何将列表按逗号划分为令牌

Question

Hi i am really new to python. I would like to ask whether based on my code below, how can I actually divide the list, inst, into tokens by comma

print("ID - actual - predicted")
for index, inst in enumerate(test):
    print "\n", inst
    pred = cls.classify_instance(inst)
    dist = cls.distribution_for_instance(inst)
    print(
        "%d - %s - %s" %
        (index+1, inst.get_string_value(inst.class_index)
         ,inst.class_attribute.value(int(pred))))
split_inst = inst.split(",")

So what I try to do is splitting it by comma. But I keep on getting error like 'Instance' object has no attribute 'split' like this:

22,in,in,1,PP,21,prep,IN,pr,null,null,null,null,null,null,the,DT,det,def,null,null,sg,null,null,system,NN,null,null,null,in,IN,recorded,VBN,NN,?
95 - ? - nonerror

Traceback (most recent call last):
 File "C:\Python FYP\Tkinter\prediction.py", line 44, in <module>
  main(sys.argv)
 File "C:\Python FYP\Tkinter\prediction.py", line 38, in main
 split_inst = inst.split(',')
AttributeError: 'Instance' object has no attribute 'split'

How can I solve this problem?

By looking at your question, you are using object for split function. so copy the object string into different variable and then try to split it.

Because objects can not splitted, it has to be string
