需要基于redis用python实现一个功能,安装好redis后,测试所用的目录结构如下:
string.py测试文件中代码如下:
import redis
r = redis.Redis(host='localhost', port=6379, db=0)
r.set('foo', 'bar')
print(r.append('foo', ' bar'))
print(r.get('foo'))
运行后出现如下错误:
Traceback (most recent call last):
File "F:/PythonProjects/web/redis_in_python/example/string.py", line 1, in <module>

首先,查看安装的redis模块中是否有Redis,结果是有的:
这个包是在pycharmpro的Project Interpreter中完成导入的,所以代码与导入应该不会有问题。
然后,修改文件名”string.py“为“字符串.py”,结果问题解决:
所以原因应该是之前的文件名与redis调用的某处代码或文件名产生冲突了,但具体地点尚不清楚。
