我有一个类,长这样:
#!/usr/bin/env python
class Foo:
def __init__(self, x):
self.x = x
def bar(self):
self.bar1_out = self.x + 5
self.bar2_out = self.x + 1
return (self.bar1_out,self.bar2_out)
def qux(self,myvalue = None):
first, second = myvalue or self.bar()
return first + 3, second + 6
def main():
"""docstring for main"""
f = Foo(5)
mbr_out1, mbr_out2 = f.bar()
print mbr_out1, "\t", mbr_out2
mqx_out1, mqx_out2 = f.qux()
print mqx_out1, "\t", mqx_out2
qout1, qout2 = f.qux((1))
print qout1, "\t", qout2
if __name__ == '__main__':
main()
我看到一些实现建议使用super
def __init__(self, x):
super(Foo,self).__init__()
self.x = x
def bar(self)
#etc.
我的问题是:
super(Foo,self).__init__()
的作用是什么?- 它与
self.x=x
有何不同? - 如何使用
super()
使我的代码产生相同的结果?
