''' The 'calc' library contains the 'add2' function that takes 2 values and adds them together. If either value is a string (or both of them are) 'add2' ensures they are both strings, thereby resulting in a concatenated result. NOTE: If a value submitted to the 'add2' function is a float, it must be done so in quotes (i.e. as a string). ''' # If 'value' is not an integer, convert it to a float and failing that, a string. def conv(value): try: return int(value) except ValueError: try: return float(value) except ValueError: return str(value) # The 'add2' function itself def add2(arg1, arg2): # Convert 'arg1' and 'arg2' to their appropriate types arg1conv = conv(arg1) arg2conv = conv(arg2) # If either 'arg1' or 'arg2' is a string, ensure they're both strings. if isinstance(arg1conv, str) or isinstance(arg2conv, str): arg1conv = str(arg1conv) arg2conv = str(arg2conv) return arg1conv + arg2conv
