Python 操作Redis
1. 安装及连接
Pip install redis
连接
import redis
# 加入Strict 严格上的，
r = redis.StrictRedis(host='localhost', port=6379, db=0)
# 兼容一些老版本啊
#r = redis.Redis(host='localhost', port=6379, db=0)
user1 = r.get('user1')
print(user1) # b'Jhon'
2. 字符串的操作
自带一些连接池
class TestString(object):
""
def __init__(self):
self.r = redis.StrictRedis(host='localhost', port=6379, db=0)
def test_set(self):
''' set -- 设置值'''
rest = self.r.set('user2','Amy')
print(rest)
return rest
def test_get(self):
''' get -- 获取值'''
rest = self.r.get('user3')
print(rest)
return rest
def test_mset(self):
''' mset -- 设置多个键值对'''
d = {
'user3':'Bob',
'user4':'Bobx'
}
rest = self.r.mset(d)
print(rest)
return rest
def test_mget(self):
'''mget == 获取多个键值对'''
l = ['user3','user4']
rest = self.r.mget(l)
print(rest)
return rest
def test_del(self):
'''del == 删除'''
rest = self.r.delete('user3')
print(rest)
def main():
str_obj = TestString()
# str_obj.test_set()
str_obj.test_get()
#str_obj.test_mset()
#str_obj.test_mget()
#str_obj.test_del()
3. 列表（List）的操作
class TestList(object):
def __init__(self):
self.r = redis.StrictRedis(host='localhost', port=6379, db=0)
def test_push(self):
''' lpush/rpush --从左/右插入数据'''
t = ('Amy', 'Jhon')
rest = self.r.lpush('l_eat3',*t)
print(rest)
rest= self.r.lrange('l_eat3',0,-1)
print(rest)
def test_pop(self):
''' lpop/rpop -- 移除最左最右的元素并返回'''
rest = self.r.lpop('l_eat3')
print(rest)
rest = self.r.lrange('l_eat3', 0, -1)
print(rest)
4. 集合（Set）的操作
# coding:utf-8
import redis
class Base(object):
def __init__(self):
self.r = redis.StrictRedis(host='localhost', port=6379, db=0)
class TestString(object):
""
def __init__(self):
self.r = redis.StrictRedis(host='localhost', port=6379, db=0)
def test_set(self):
''' set -- 设置值'''
rest = self.r.set('user2','Amy')
print(rest)
return rest
def test_get(self):
''' get -- 获取值'''
rest = self.r.get('user3')
print(rest)
return rest
def test_mset(self):
''' mset -- 设置多个键值对'''
d = {
'user3':'Bob',
'user4':'Bobx'
}
rest = self.r.mset(d)
print(rest)
return rest
def test_mget(self):
'''mget == 获取多个键值对'''
l = ['user3','user4']
rest = self.r.mget(l)
print(rest)
return rest
def test_del(self):
'''del == 删除'''
rest = self.r.delete('user3')
print(rest)
class TestList(object):
def __init__(self):
self.r = redis.StrictRedis(host='localhost', port=6379, db=0)
def test_push(self):
''' lpush/rpush --从左/右插入数据'''
t = ('Amy', 'Jhon')
rest = self.r.lpush('l_eat3',*t)
print(rest)
rest= self.r.lrange('l_eat3',0,-1)
print(rest)
def test_pop(self):
''' lpop/rpop -- 移除最左最右的元素并返回'''
rest = self.r.lpop('l_eat3')
print(rest)
rest = self.r.lrange('l_eat3', 0, -1)
print(rest)
class TestSet(Base):
def test_sadd(self):
''' sadd -- 添加元素'''
l = ['Cat','Dog']
rest = self.r.sadd('zoo3',*l)
print(rest)
rest = self.r.smembers('zoo3')
print(rest)
def test_srem(self):
''' srem === 删除元素'''
rest = self.r.srem('zoo2', 'Dog')
print(rest)
rest = self.r.smembers('zoo2')
print(rest)
def test_sinter(self):
''' sinter --- 返回几个集合的交集'''
rest = self.r.sinter('zoo2','zoo3')
print(rest)
def main():
str_obj = TestString()
# str_obj.test_set()
#str_obj.test_get()
#str_obj.test_mset()
#str_obj.test_mget()
#str_obj.test_del()
# 列表
#list_obj = TestList()
#list_obj.test_push()
#list_obj.test_pop()
# 集合
set_obj = TestSet()
#set_obj.test_sadd()
# set_obj.test_srem()
set_obj.test_sinter()
