### 介绍

Lru适合做定量的数据新旧替换的算法,特别适合做缓存的应用,后期会考虑接入redis做存储。


```python


from pyLruCache import *
In [1]: from pyLruCache import *

In [2]: a = pyLruListCache(3)

In [3]: for i in a.iteritems():
...: print i
...:

In [4]:

In [4]: a[1] = 1

In [5]: a[2] = 2

In [6]: a[3] = 3

In [7]: for i in a.iteritems():
...: print i
...:
(1, 1)
(2, 2)
(3, 3)

In [8]: a[4] = 4

In [9]: for i in a.iteritems():
print i
...:
(2, 2)
(3, 3)
(4, 4)

In [10]: print a[2]
2

In [11]: a[5] = 5

In [12]: for i in a.iteritems():
print i
....:
(4, 4)
(2, 2)
(5, 5)

In [13]: a[6] = []

In [14]: a[6].append(1)

In [15]: a[6].append(2)

In [16]: a[6].append(3)

In [17]: for i in a.iteritems():
print i
....:
(2, 2)
(5, 5)
(6, [1, 2, 3])

In [18]: a[7]=7

In [19]: for i in a.iteritems():
print i
....:
(5, 5)
(6, [1, 2, 3])
(7, 7)
```

###for List
```python
rom pyLruCache import pyLruListCache

a = pyLruListCache(5)

for i in range(100):
a.appendd(i)
```
the result in debug mode

{96: 96, 92: 92, 93: 93, 94: 94, 95: 95}
92

{96: 96, 97: 97, 93: 93, 94: 94, 95: 95}
