Consider the following code:

import csv
import sys
FILENAME = "names.csv"
def main():
    try:
        names = []
        with open(FILENAME, newline="") as file:
            reader = csv.reader(file)
            for row in reader:
                names.append(row)
    except FileNotFoundError as e:
        print("Could not find " + FILENAME + " file.")
        sys.exit()
    except Exception as e:
        print(type(e), e)
        sys.exit()
    print(names)       
if __name__ == "__main__":
    main()
