Filtring csv file datas and save them another csv file using Python

Question

I have a .csv file that has data like that:

index, name,    id
1      john     512
2      Anne     895
3      Angel    897
4      Lusia    777

So I want to filter them by name endings and get names only which have vowel endings. And the result must be like that:

    index, name,     id
    1      Anne     895
    2      Lusia    777

After filtering, I want to save the result in another .csv file. I am trying various ways to get the correct result, However, I could not do that. please help me 🙁

Trying before asking questions helps improve coding skills

import csv


def read_csv(filename, outfile="res.csv"):
    vowel = {"a", "e", "i", "o", "u"}
    with open(filename, 'r') as f, open(outfile, 'w', newline="") as out:
        out.write(f.readline())        # write header
        reader = csv.reader(f, delimiter=' ', skipinitialspace=True)   # space-separate and skip extra spaces
        writer = csv.writer(out)      # csv write object

        # Filter out lines that don't end with a vowel
        writer.writerows(line for line in reader if line[1][-1] in vowel) 


read_csv("a.csv", outfile="res.csv")
