无意中看到了python类的继承中super的妙用，结合自己的实践，记录一下：
总结为一句话：如果要用super，那么父类必须继承自object类（包括初始化函数继承和类函数继承），否则会编译不通过
代码：
#!/usr/bin/python
import sys
import getopt
#import math
#coding=utf8
class AA:
def __init__(self,a):
print "AA class"
self.a=a
print "self.a:",self.a
class BB(AA):
def __init__(self,b):
print "BB class"
super(BB,self).__init__(b)
self.a=b
print "self.a:",self.a
def aa(self,n):
print "n:",n
if __name__ == "__main__":
a=AA(10)
b=BB(11)
print "b:",b
错误提示：
File "aa.py", line 19, in __init__
super(BB,self).__init__(b)
TypeError: super() argument 1 must be type, not classobj
正确代码：
#!/usr/bin/python
import sys
import getopt
#import math
#coding=utf8
class AA(object):
def __init__(self,a):
print "AA class"
self.a=a
print "self.a:",self.a
def aa(self,m):
print "m:",m
for i in range(0,10):
print i*2;
class BB(AA):
def __init__(self,b):
print "BB class"
#super(BB,self).__init__(b)
self.a=b
print "self.a:",self.a
def aa(self,n):
print "n:",n
print "BB'aa"
super(BB,self).aa(n)
if __name__ == "__main__":
a=AA(10)
b=BB(11)
b.aa(15)
结果：
AA class
self.a: 10
BB class
self.a: 11
n: 15
BB'aa
m: 15
