如何显示列表中的特定列，将它们制成表格并在控制台上打印

Question

i am currently trying to do some password manager and i am stuck on how to elegantly print specific colums from a list. I could do this in a very dirty way but im sure there has to be a one-line way of managing it. The csv_file has 3 colums: "service", "account" and "password". I want to show only the firtst two colums that satisfies the user input in a tabulated way, to imitate a table. Thank you in advanced for your time: ). This is how I tried to do it:

        reader = csv.DictReader(csv_file)
        service = input("PLEASE SPECIFY THE SERVICE \n ")
        header=[["service","account"]]
        for line in reader:
            if line["service"] != service:
                reader.remove(line)
        print(tabulate(([header, [el["service"], el["account"]] for el in reader]))

Answer 1

How about this?

reader = csv.DictReader(csv_file)
service = input("PLEASE SPECIFY THE SERVICE \n ")
print(tabulate(line for line in reader if line["service"] == service,
               header=["service","account"])

Answer 2

After a long investigation i found a way of doing it:

service = input("PLEASE SPECIFY THE SERVICE \n")
reader = csv.DictReader(csv_file)
header=["service","account"]
valid=[]
for line in reader:
    if line["service"] != service:
        valid.append([line["service"], line["account"], line["password"]])
print(tabulate([header, *[[line[0], line[1]] for line in valid]]))
