isinstance(object,class-or-type-or-tuple)--> bool ,判断一个object是否属于后面的类型～返回True或者False
答案太醉了，为啥不能
t = ('a', 'b',tuple(['A', 'B']))
print t
t = ('a', 'b',tuple(['A', 'B']))
print t

def move(n, a, b, c,current):
if n==1 and current == 1:
return a+'==>'+c
if n==1 and current != 1:
print a+'==>'+c
return move(current-1, b, a, c,current-1)
print a+'==>'+b
return move(n-1, a, b, c,current)
print move(4, 'A', 'B', 'C',4)
这样写只要10步搞定 多加了一个参数

def average(*args):
sum=0.0
avg=0.0
n=1
for x in args:
sum=sum+x
avg=sum/n
n=n+1
if n!=0:
return avg
print average()
print average(1, 2)
print average(1, 2, 2, 3, 4)
感觉写成了C程序
