Post #438

# In Python 3 you can use a bare "*" asterisk # in function parameter #lists to force the # caller to use keyword arguments for certain # parameters: »> def f(a, b, *, c='x', d='y', e='z'): ... return 'Hello' # To pass the value for c, d, and e you # will need to explicitly pass it as # "key=value" named arguments: »> f(1, 2, 'p', 'q', 'v') TypeError: "f() takes 2 positional arguments but 5 were given" »> f(1, 2, c='p', d='q',e='v') 'Hello'
