What is wrong with this code?? Can you tell what it does?? import art n1 = 0 n2 = 0 selected_operation = "" solution = 0 def add (n1, n2): return n1 + n2 def subtract (n1, n2): return n1 - n2 def multiply (n1, n2): return n1 * n2 def divide (n1, n2): return n1 / n2 operations = { "+" : add, "-" : subtract, "*" : multiply, "/" : divide } def rest_of_calculation (): print ( "+ \n - \n * \n /" ) selected_operation = input ( "Pick an operation: " ) n2 = float ( input ( "What is the next number?: " )) for key in operations: if key == selected_operation: solution = operations[key](n1, n2) print ( f" { n1 } { key } { n2 } = { solution } " ) print (art.logo) n1 = float ( input ( "What is the first number?: " )) rest_of_calculation() while True : new_calculation = input ( f"Type 'y' to continue calcu...
