python函数是否可以使用未指定数量的参数？

Question

Can there be python functions that take unspecified number of arguments such as

myfunc(a, b, c)

myfunc(a, b, c, d, e)

where both will work?

Answer 1

myfunc(*args, **kw)

*args - takes N number of arguments

**kw - takes dictionary (unspecified depth)

In [1]: def myfunc(*args):
   ...:     print args
   ...:

In [2]: myfunc(1)
(1,)

In [3]: myfunc(1,2,3,4,5)
(1, 2, 3, 4, 5)
