返回的数据类型不是字符串，却用了get方法

1、字符串

# ex过期时间 单位秒S
 r.set('name', 'Jack', ex=20)
 rst = r.get('name')
 print(rst)
 
 
 结果：　"Jack"

2、列表 -list

r.lpush('object', 'one')
 r.lpush('object', 'two')
 r.lpush('object', 'three')
 r.lpush('object', 'four')
 r.lpush('object', 'five')
 r.lpush('object', 'six')
 ret = r.lrange('object', 0, 5)
 print(ret[::-1], len(ret))
   
  
 结果：　['one', 'two', 'three', 'four', 'five', 'six'] 　6

3、hash类型

r.hset('user:info', 'name', 'Jack')
 r.hset('user:info', 'age', 20)
 r.hset('user:info', 'phone', '18712909999')
 r.hset('user:info', 'email', '[email protected]')
 rst = r.hgetall('user:info')
 print(rst)


 结果：　{'age': '20', 'email': '[email protected]', 'name': 'Jack', 'phone': '18712909999'}

4、集合类型 -set

r.sadd('set', 'one')
 r.sadd('set', 'two')
 r.sadd('set', 'three')
 res = r.smembers('set')
 print(res)


 结果：　{'two', 'one', 'three'}

5、有序集合类型

r.zadd('mark', 'one', 1)
 r.zadd('mark', 'two', 2)
 r.zadd('mark', 'three', 3)
 r.zadd('mark', 'four', 4)
 r.zadd('mark', 'five', 5)
 result = r.zrange('mark', 0, 10)
 print(result)


 结果：　['one', 'two', 'three', 'four', 'five']

根据不同需要，选择不同方法
