Question

all_filenames = [i for i in glob.glob("/home/greenvulcano/Scrivania/File_csv/*.csv")] dest_file = "/home/greenvulcano/Scrivania/Unione_files.csv" tag = ["inclination","deformation","temperature"] content = [] for file_name in sorted(all_filenames): with open(file_name, "r") as f: lines = f.readlines() for i, l in enumerate(lines): if len(content) == 0: content.append(l) elif i != 0: content.append(l) with open(dest_file, "w") as f: f.writelines(content) seleziona = input("Inserisci le colonne che vuoi visualizzare: ") with open(dest_file, "r") as f: titoli = f.readline().split(",") indici = [] for titolo in titoli: titolo_split = titolo.split('*') if seleziona in titolo_split: indice = titoli.index(titolo) indici.append(indice) righe = f.readlines() lista = [] for riga in righe: rigasplit = riga.split(",") for i in indici: lista.append(rigasplit[i])

Answer 1

I guess you can use:

test.csv

id,name,dob
1,pedro,2000-01-01
2,nuno,1999-01-01

import csv
csv_file = "test.csv"
seleziona = input("Inserisci le colonne che vuoi visualizzare: ").strip()
with open(csv_file) as f:
    reader = csv.DictReader(f, delimiter=',')
    for row in reader:
        print(row[seleziona])
