연결 스크립트를 실행할 때 "오류 21 : 디렉터리입니다"

Question

일부 csv 파일을 세로로 연결하는 프로그램을 작성했습니다. 여기에 프로그램이 있습니다.

import os 
import glob 
import pandas 

def concatenate(indir, outfile, colnames): 
    os.chdir(indir) 
    fileList=glob.glob('*.csv') 
    dfList=[] 
    for filename in fileList: 
     print(filename) 
     df=pandas.read_csv(filename,header=None) 
     dfList.append(df) 
    concatDf=pandas.concat(dfList,axis=0) 
    concatDf.columns=colnames 
    y=str(input("What do you want to name your file?")) 
    concatDf.csv_path = y 
    concatDf.to_csv(outfile,index=None) 


def main(): 
    indir = str(input("What is the directory that you want to concatenate?")) 
    outfile = str(input("What is the directory that you want to export the merged file to?")) 
    string_input = input("What are the column names?: ") 
    input_list = string_input.split() 
    colnames = [str(x) for x in input_list] 
    concatenate(indir, outfile, colnames) 

그러나 프로그램을 테스트 할 때 약간의 오류가 있습니다. 다음은 나의 의견입니다.

main() 

What is the directory that you want to concatenate?/Users/hem/Desktop/Complete_Pilot_Copy/5555_1/DelayDiscounting 

What is the directory that you want to export the merged file to?/Users/hem/Desktop/DelayedDiscountingAnalyzed 

What are the column names?: Date SubjectID SessionID ProtocolID SiteID TaskID UserResponse LogDiscountRate LogDiscountRateStd QuestionRule NegativeDiscountFlag ZeroDiscountFlag BozoDiscountFlag gldomain ProposedValue1 ProposedDelay1 ProposedValue2 ProposedDelay2 ProposedValue3 ProposedDelay3 TrialStartTimeSec ResponseTimeSec

DDT_5555_1_HUBS071501_BU_062016_140010.csv 
DDT_5555_1_HUBS071501_BU_062016_140051.csv 
DelayedDiscounting_5555_1.csv

    f = open(path, mode, errors='replace') 

IsADirectoryError: [Errno 21] Is a directory: '/Users/hem/Desktop/DelayedDiscountingAnalyzed' 

어떻게 수정하나요? 나는 그것이 내가 전화 번호부에 들어 왔던 방법일지도 모른다라고 생각한다? 감사합니다

오류가 거의 모든 말은 outfile 디렉토리가 아닌 파일의 경로 여야합니다. 그래서 그 대신이

y=str(input("What do you want to name your file?")) 
concatDf.csv_path = y 
concatDf.to_csv(outfile,index=None) 

의이 작업을 수행 : 내가 볼

y=str(input("What do you want to name your file?")) 
concatDf.to_csv(os.path.join(outfile, y),index=None)
