使用 python 从 csv 文件中获取最后一列的最后一行

Question

Hello I have a csv file that contains those columns:

index, text , author , date 

i want to select the last column from the last inserted row

what i did so far:

inputFile = 'bouyguesForum_results.csv'
f1 = open(inputFile, "r")
last_line = f1.readlines()[-1]
f1.close()
print (last_line)

this code gets me the last inserted row but i want to select the last column which is the date column

code output:

9,"J'ai souscrit à un abonnement Bbox de 6€99 + 3€ de location de box, sauf que j'ai été prélevé de 19€99 ce mois-ci, sachant que je n'ai eu aucune consommation supplémentaire, ni d'appel, et je n'ai souscrit à rien, et rien n'est précisé sur ma facture. Ce n'est pas normal, et je veux une explication.",JUSTINE,17 novembre 2021

thank you for your time.

Answer 1

You can do this: if you want the very last row

with open('data.csv', 'r') as csv:
    data = [[x.strip() for x in line.strip().split(',')] for line in csv.readlines()][-1][-1]
    print(data)

or if you want all the last elements in each row

with open('data.csv', 'r') as csv:
    data = [line.strip().split(',')[-1] for line in csv.readlines()]
    print(data)

Answer 2

Since you got the last row, now you can just split it into a list. Sample-

last_line = last_line.strip("\n")
last_line = [x for x in last_line.split(",") if x!=""]
last_date = last_line[-1]
