I want to be able to turn csv file into a list of lists .
my csv file is like that :

['juridiction', 'audience', 'novembre'],['récapitulatif', 'information', 'important', 'octobre'],['terrain', 'entent', 'démocrate'],['porte-parole', 'tribunal', 'monastir', 'farid ben', 'déclaration', 'vendredi', 'octobre', 'télévision', 'national', 'mère', 'fillette', 'an', 'clandestinement', 'italie', 'juge', 'instruction', 'interrogatoire', 'père'],['disposition', 'décret', 'vigueur', 'premier', 'octobre'],['décret', 'loi', 'numéro', '2022', 'octobre', 'disposition', 'spécial', 'amélioration', 'efficacité', 'réalisation', 'projet', 'public', 'priver', 'jort', 'vendredi', 'octobre'],['avocat', 'rahal jallali', 'déclaration', 'vendredi', 'octobre', 'tap', 'militant', 'membre', 'section', 'bardo', 'ligue', 'droit', 'homme', 'membre', 'association', 'damj', 'saif', 'ayadi', 'jeune', 'juge', 'instruction', 'tribunal', 'instance'],...

into

list1 = [['juridiction', 'audience', 'novembre'],['récapitulatif', 'information', 'important', 'octobre'],['terrain', 'entent', 'démocrate'],['porte-parole', 'tribunal', 'monastir', 'farid ben', 'déclaration', 'vendredi', 'octobre', 'télévision', 'national', 'mère', 'fillette', 'an', 'clandestinement', 'italie', 'juge', 'instruction', 'interrogatoire', 'père'],['disposition', 'décret', 'vigueur', 'premier', 'octobre'],['décret', 'loi', 'numéro', '2022', 'octobre', 'disposition', 'spécial', 'amélioration', 'efficacité', 'réalisation', 'projet', 'public', 'priver', 'jort', 'vendredi', 'octobre'],['avocat', 'rahal jallali', 'déclaration', 'vendredi', 'octobre', 'tap', 'militant', 'membre', 'section', 'bardo', 'ligue', 'droit', 'homme', 'membre', 'association', 'damj', 'saif', 'ayadi', 'jeune', 'juge', 'instruction', 'tribunal', 'instance'],...]]

Ive try to solve this but no success :

import csv
from itertools import zip_longest

with open('/content/drive/MyDrive/tokens.csv') as csvfile:
    rows = csv.reader(csvfile)
    res = list(zip_longest(*rows))
    list1 = [list(filter(None.__ne__, l)) for l in res]
    print(res2)

but the output is :

[["['juridiction'"], [" 'audience'"], [" 'novembre']"], ["['récapitulatif'"], [" 'information'"], [" 'important'"], [" 'octobre']"], ["['terrain'"], [" 'entent'"], [" 'démocrate']"],...

Answer 1

Call list.append:

with open('file.csv') as csvfile:
    rows = csv.reader(csvfile)
    list1 = []
    for row in rows:
        list1.append(row)

If your file really consists of only one long line, then here’s a couple of options:

Use eval: You need to add the brackets for the outer list.

with open("data.csv", "r") as file:
    data = eval("[" + file.read().strip() + "]")

Use json: You need to (1) add the outer brackets, and (2) replace the ' with " to make the string json compliant.

import json

with open("data.csv", "r") as file:
    data = json.loads("[" + file.read().strip().replace("'", '"') + "]")

Use string manipulation: You need to (1) remove the brackets at the edges, then (2) remove the 's, then (3) .split anlong "],[", and finally (4) .split the parts along ", ".

with open("data.csv", "r") as file:
    data = [
        string.split(", ")
        for string in file.read().strip().strip("[]").replace("'", "").split("],[")
    ]

(Replace data.csv with your file path.)
