Why does my code print "built-in method" and some hex numbers?

Here is my Key function:

def Key(message, decision):
    key = input("Input the key which will be used to encode the message.\n".lower)
    n = 0
    for i in range(len(key)):
        if 64 < ord(key[n]) < 91:
            raise ValueError(key[n], "is a capital letter!")
        else:
            n = n+1
    Keycode(decision, message, key)

When I call it and input the message and press enter it comes up with:

built-in method lower of str object at 0x0150E0D0

What's wrong? How can I fix it?

.lower() method is a method of the str class. .lower() converts the string to lowercase. in order To call the lower() method you need to write the name of the method(.lower or .upper), followed by parentheses().

key = input("Input the key which will be used to encode the message.\n".lower)

Because lower function is missing parenthesis, put parenthesis after function call. so syntax would be like key = input("Input the key which will be used to encode the message.\n".lower())

You need to use closed pair of parenthesis after lower

key = input("Input the key which will be used to encode the message.\n".lower())

After .upper or .lower there has to be a closed pair of parentheses. You can put custom arguments in them but if you just want to capitalize the input leave them empty.

Example:

user=(input("Enter a letter:")).upper()

This will change case to upper.

Key contains this problematic line:

key = input("Now, input the key which will be used to encode the message.\n".lower)

which passes as input to input the lower method of a string, when you (presumably) want to pass the string and then apply lower to what input returns.

Try saving your work in your work space. If you're using the Python prompt to check your results, use the exit() command and open a Python prompt again. Then try calling the previous functions as you were doing earlier on.
