在原来python2里有一个函数apply来做这种事情，如下：
# File: builtin-apply-example-1.py def function(a, b): print a, b apply(function, ("whither", "canada?")) apply(function, (1, 2 + 3))# File: builtin-apply-example-2.py def function(a, b): print a, b apply(function, ("crunchy", "frog")) apply(function, ("crunchy",), {"b": "frog"}) apply(function, (), {"a": "crunchy", "b": "frog"})现在换成python3了，就不能这样使用了，因为这个函数已经不再使用了。那么怎么办呢？
可以如下调用：
# File: builtin-apply-example-1.py def function(a, b): print(a, b) #apply(function, ("whither", "canada?")) #apply(function, (1, 2 + 3)) function(*("whither", "canada?")) function(*(1, 2 + 3))# File: builtin-apply-example-1.py def function(a, b): print(a, b) #apply(function, ("whither", "canada?")) #apply(function, (1, 2 + 3)) function(*("whither", "canada?")) function(*(1, 2 + 3)) function(**{"a": "crunchy", "b": "frog"})可以看到采用*元组、**字典的方式调用。
