如何使用fuzzywuzzy连接两个数据集

Question

我们有两个数据框

数据框 1 ::

数据框 2：

需要在组合列中验证第二个数据集中的相同数据，并从第一个数据集中添加 id 列

表示输出，如 ::

!pip install fuzzywuzzy
from fuzzywuzzy import fuzz
data = pd.read_csv(dataframe 1)
df = pd.read_csv(dataframe 2)

word = data['data'].tolist()
find = df['combined'].tolist()
df_final = pd.DataFrame(columns=['combined','id'])
for j in find:
    j = str(j)
    for i in word:
        if i:
            i = str(i)
            Token_Sort_Ratio = fuzz.token_sort_ratio(j,i)
            if Token_Sort_Ratio > 70:
                #print(i)
                final = data[data.data == i]
                df1 = df[df.combined == j]
                df_final['id']=df_final['id'].append(final['id'],ignore_index=True)
                df_final['combined']= df_final['combined'].append(df1['combined'],ignore_index=True)

但数据没有附加到 df_final 数据集中， 请帮我解决这个问题。 之后我们计划在合并列上加入 df_final 和 dataframe 2

如果您有任何其他解决方案，请随时提出建议

Answer 1

import pandas as pd 
from fuzzywuzzy import fuzz

df1 = pd.DataFrame([['12','gandhi vidhalaya 225'],['45','balvidhya mandir a 456'],['65','jspm 4568'],[45,'coep 7896']], columns= ['id','data'])

df2 = pd.DataFrame([['june','gandhi vidhalaya dc 225'],['july','balvidhya mandir a 456'],['march','jspm d 4568'],['jan','coep 7896']], columns= ['month','combined']) 


data = []
for i in range(df1.shape[0]):
    for j in range(df2.shape[0]):
        token_ratio =  fuzz.ratio(df1['data'][i], df2['combined'][j])
        if token_ratio > 70:
           column_B = df2.iloc[j]['combined']
           column_A = df2.iloc[j]['month']
           data.append((column_B, column_A))

df_final = pd.concat([df1,pd.DataFrame(data, columns  = ['combined_text','month'])], axis = 1)

#Op drop the data column you will get the desired result
df_final.drop(columns = ['data'])
