Learning Python, newbie question about strings and evaluation

[new_learner_999]

Aha! Okay. Many thanks - I think I understand... if I have, I tried the following:

def assign_order(str1, str2, str3):
    return str3 > str2 > str1

result = assign_order("c", "b", "a")

print(result)

and which prints false

I'd like to understand what's going on here. Am I correct in thinking the function is designed to accept three inputs - those could be any type, correct? But by defining result to use strings something else then happens? Why otherwise would it return "false"?

Can I essentially force a string to be "greater than" another string by using a function (or any other means?).
