在下面的方法定义,什么是*和**为做param2？

def foo(param1, *param2):
def bar(param1, **param2):

是否有语法允许您将列表扩展为函数调用的参数？

例:

# Trivial example function, not meant to do anything useful.
def foo(x,y,z):
   return "%d, %d, %d" %(x,y,z)

# List of values that I want to pass into foo.
values = [1,2,3]

# I want to do something like this, and get the result "1, 2, 3":
foo( values.howDoYouExpandMe() )
