Calculate moving averages

Title: to do by using the input generator calculates a time average value of each.

def init(func):
    def inner(*args,**kwargs):
        g = func(*args,**kwargs)
        g.__next__()
        return g
    return inner
@init
def avgrage():
    sum = 0
    count = 0
    avg = 0
    while True:
        num = yield avg
        sum += num
        count += 1
        avg = sum/count

avg_g = Avgrage () 
right = avg_g.send (10 )
 the printer (right) 
right = avg_g.send (76 )
 the printer (right)

By a generator mounted on a decorator, may be less time to write one line of code is input.

If not decorator

def avgrage():
    sum = 0
    count = 0
    avg = 0
    while True:
        num = yield avg
        sum += num
        count += 1
        avg = sum/count

avg_g = avgrage()
avg_g.__next__()
ret = avg_g.send(10)
print(ret)
ret = avg_g.send(76)
print(ret)

对比而言，加了装饰器可以在输入的时候少写一行代码、

avg.__next__()

(⊙﹏⊙)，虽然对程序猿来说好像代码更多了。

但是在用户角度来说，更显方便。
