python 常用函数举例

1 apply 函数

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
