python 常用函数举例

 

def printInfo(id,name,address):

    print 'id is ',id,' and name is ',name,' and address is ',address

 

 

1.1 调用printInfo函数

 

printInfo(1,'flankwang','HeNan KaiFeng')

 

1.2 调用printInfo函数

 

apply(printInfo,(1,'flankwang','HeNan KaiFeng'))

 

1.1 和1.2效果一样

 

 

 

 

2 __call__ 函数

 

class CallDemo(object):

    def __init__(self):

        print 'this is __init__ method'

    def __call__(self):

        print 'this is __call__ method'

 

调用：

 

CallDemo()()

 

结果：

 

this is __init__ method

this is __call__ method
