查找在另一个列表的列表中找到的关键字的出现次数

Question

import nltk
import random
from nltk.tokenize import word_tokenize
from nltk.corpus import stopwords
from string import punctuation
from collections import Counter
import csv
import pandas as pd

从CSV获取数据：

address = 'filepath'
example = pd.read_csv(address)
review_column = example.Reviews 

获得的数据并将其插入列表

reviews = []
for w in review_column:
    reviews.append(w)

通过删除停用词和标点符号进一步增强列表中的数据。

reviews = [word for word in reviews if word not in stopwords.words('english')] 
reviews = [word for word in reviews if word not in punctuation]     
#reviews = [word_tokenize(i) for i in reviews]

从CSV获取数据

address = 'filepath'
example = pd.read_csv(address)
keywords_column = example.Keywords 

将数据插入列表

keywords = []
for w in keywords_column:
    keywords.append(w)

#keywords_tokenised = []
#keywords_tokenised = [word_tokenize(i) for i in keywords]

frequency_list = []
frequency = 0 
for word in keywords:    
    if word == reviews:
        frequency += 1
        frequency_list.append((word,frequency))
    else:
        frequency_list.append((word,frequency))
print(frequency_list)
