Hello Nicholas,

You have defined the function, but the function is never invoked. If you want to invoke the function you could do so like this.

def alpha():

    if say == call:
        alpha()

    for step in enumerate(my_alpha):
        print('{}: {}'.format(*step))

my_alpha = list('abcdefghijklmnopqrstuvwxyz')
call = 'call'
say = int(input("Say smthin "))
alpha();

I hope this helps.

Uhm, Thanks for taking time to reply but I still get this ValueError for the Call variable

Whenever i type call into the shell I wish it could give me the alpha_list back. BUt instead i get a ValueError.

Hope you can help me :p

Ah, that's because you're trying to cast the string coming from the input method to an int.

say = int(input("Say smthin "))

Input will always return a string and if you type 'call' for the input, it will attempt to cast that to an integer and fail.

I'm not sure what you want the program to do, but if you type 'call' for the input, you're going to end up with a RecursionError because the alpha function will recursively call itself, since there's no loop to change the value of the say variable.
