insurance_qa_data_helper.py中build_vocab()函数不能理解

[jozerozero]

第14行
def build_vocab():
code = int(0)
vocab = {}
vocab['UNKNOWN'] = code
code += 1
for line in open('/export/jw/cnn/insuranceQA/train'):
items = line.strip().split(' ')
for i in range(2, 3)://就是这一行,为什么不是range(2, 4)
words = items[i].split('_')
for word in words:
if not word in vocab:
vocab[word] = code
code += 1

同问，也觉得应该是range(2, 4)而不是2到3
