如何加密并写入文本文件？

Question

I have the code shown below, which is supposed to encrypt whatever is in the (data) parameter, but when I open the text file, it just lists all the data as 'none'. Why is this?

print("Welcome to Caprigel's Password Manager v1.0!\n")

username = input("Enter username for website: ")
password = input("Enter password for website: ")
url = input("Enter website url: ")

def encrypt(data):
    listed = list(data)

    char_as_ints = []

    for char in listed:
        char_as_int = ord(char)
        char_as_int_conv = char_as_int + 64
        char_as_ints.append(char_as_int_conv)

    print(char_as_ints)

with open("pmdata.txt", "a") as f:
    enc_user = encrypt(username)
    enc_pass = encrypt(password)
    enc_url = encrypt(url)

    f.write(f'''

                Username: {enc_user}
                Password: {enc_pass}
                Url: {enc_url}


                                            ''')

Your encrypt function doesn't explicitly return anything, meaning it implicitly returns None . Instead of printing char_as_ints , you should return it:

def encrypt(data):
    listed = list(data)

    char_as_ints = []

    for char in listed:
        char_as_int = ord(char)
        char_as_int_conv = char_as_int + 64
        char_as_ints.append(char_as_int_conv)

    return char_as_ints # Here!
