python - 튜플 대신 Integer로 열 업데이트

3 개의 열이있는 데이터 프레임이 있고 튜플 목록 인 해당 데이터 프레임의 두 번째 열만 반복하고 싶습니다. 해당 목록에서 각 튜플의 마지막 요소 만 추가하고 싶습니다

fuzzywuzzy를 사용하여 텍스트 일치 스크립트를 만들었습니다.

import pandas as pd
from fuzzywuzzy import process, fuzz

pd.set_option('display.width', 1000)
pd.set_option('display.max_columns', 10)
data = pd.read_csv(r"address_details.csv", skiprows=0)
id = data['COD_CUST_ID'].values.tolist()
address = data['ADDRESS'].values.tolist()
dict_list=[]
for i in range(0,len(id)):
    for add in range(0,len(address)):
        score=process.extractBests(address[add], address, limit=len(address), score_cutoff=40)
        #print(score)
        dict_={}
        dict_.update({"Cust_Id": id[i]})
        dict_.update({"Match Ratio": score})
        dict_.update({"Search String": address[add]})
        #dict_.update({"Address List": address})
        dict_list.append(dict_)
df=pd.DataFrame(dict_list)
print(df)
s=df.to_csv("match_score.csv",sep=',',index=None)

답변 # 1

열 이름이 명확하지 않으므로 일반 코드를 작성하고 있습니다.

이 튜플의 세 번째 요소로 B 열을 업데이트하고 있습니다.

도움이 되길 바랍니다 :)

df['B'] = df['B'].apply(lambda x: x[0][1])

샘플 프로그램 ::

import pandas as pd
Cars = {'A': [21527575],
        'B': [[('H.NO.407,ROOM NO.310. 3RD FLOOR MAQBOOL APARTMENT APARTMENT OPP, RABIYA MASJID MANGAL BAZAR SLAP KOT THANE MAHARASHTRA 421302', 100)]],
        'C' : [' H.NO.407,ROOM NO.310. 3RD FLOOR MAQBOOL APARTMENT APARTMENT OPP, RABIYA MASJID MANGAL BAZAR SLAP KOT THANE MAHARASHTRA 421302']
        }
data = pd.DataFrame(Cars)
data['B'] = data['B'].apply(lambda x: x[0][1])
print(data)

출력 ::

    A    B                                                  C

데이터 프레임이 약간 불분명했습니다.

문제가 해결되는지 확인하십시오.

import pandas as pd
# Sample data frame
data = pd.DataFrame({'a': [1, 2, 3], 'b': [[(1, 2)], [(2, 3)], [(3, 4)]]})
print(data)
# Data
   a         b
0  1  [(1, 2)]
1  2  [(2, 3)]
2  3  [(3, 4)]
# Fix
# [-1] selects last element in tuple
data['b'] = data['b'].apply(lambda x: x[0][-1])
print(data)
# Result
   a  b
0  1  2
1  2  3
2  3  4
