Python“列表”对象不可调用错误

Question

我正在尝试使用“ gensim.models.doc2vec.TaggedDocument”读取然后合并2个列表，但问题是“'list'对象不可调用”。怎么办呢？

import csv

listOfTags = []
listOfTokens = [] 

with open('coreTag.csv', 'r') as csvfile: #reading of the 1st file
    reader = csv.reader(csvfile)
    for row in reader:
        listOfTags.append(row)

with open('1core.csv', encoding="utf8") as csvfile: #reading and tokenizing the 2nd file
    reader = csv.reader(csvfile)
    for row in reader:
        token = gensim.utils.simple_preprocess(str(row))
        listOfTokens.append(token)

for i in listOfTokens: #trying to combine them here
    for x in listOfTags:
        train_corpus = list(gensim.models.doc2vec.TaggedDocument([i], [x])) #<-error is here

完整错误消息：
