Hi guys, i'm dynamically calling a function the name of

which comes from the input string using getattr (i know it can be unsafe, but it's a learning test server on my courses), but not all functions take 2 arguments, is there a way to truncate the arguments i'm passing dynamically to comply with the amount the function requires?

operands = (args.operand_1, args.operand_2) return...
