Bug report

Bug description:

Setting the same name parameters gets the error message saying duplicate argument as shown below:

def func(param, param):
    pass

SyntaxError: duplicate argument 'param' in function definition

Setting * after all the parameters gets the error message saying at least one argument as shown below:

def func(param1, param2, *):
    pass

SyntaxError: named arguments must follow bare *

So, argument should be replaced with parameter as shown below:

SyntaxError: duplicate parameter 'param' in function definition

SyntaxError: named parameters must follow bare *

*You can also see this issue.
