Answer:
You OR expressions are wrong.
Explanation:
Rather than writing:
if method == "Square" or "square":
You should write:
if method == "Square" or method == "square":
The expression should evaluate to something that is true or false.
In the above case, the expression is method == "Square" or method == "square" which can are actually two sub-expressions with an or in between them:
subexpr1 or subexpr2
each of the sub-expressions should evaluate to true or false.
method == "Square" is one of those sub-expressions.
That is how an expression is broken down by the compiler.
TIP: If you would add method = method.lower() right after the input, you could simplify all the if statements by removing the uppercase variants.
