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'] 　63、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', '123@gmail.com')
rst = r.hgetall('user:info')
print(rst)

结果：　{'age': '20', 'email': '123@gmail.com', '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
