Python3 rabbitmq NameError问题求助，python3nameerror,学习使用rabbitmq

学习使用rabbitmq，遇到麻烦

python3.3.2rabbitmq3.4.1pika-0.9.14

python send.py

Traceback (most recent call last):  File "send.py", line 3, in <module>    connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))  File "/home/hawk/g/sqlalchemy/lib/python3.3/site-packages/pika/connection.py", line 361, in __init__    if host and self._validate_host(host):  File "/home/hawk/g/sqlalchemy/lib/python3.3/site-packages/pika/connection.py", line 207, in _validate_host    if not isinstance(host, basestring):NameError: global name 'basestring' is not defined------------------------------------------------------------python receive.py Traceback (most recent call last):  File "receive.py", line 5, in <module>    host='localhost'))  File "/home/hawk/g/sqlalchemy/lib/python3.3/site-packages/pika/connection.py", line 361, in __init__    if host and self._validate_host(host):  File "/home/hawk/g/sqlalchemy/lib/python3.3/site-packages/pika/connection.py", line 207, in _validate_host    if not isinstance(host, basestring):NameError: global name 'basestring' is not defined

这是什么情况？

===========================Python 3.3.2+ (default, Feb 28 2014, 00:52:16) [GCC 4.8.1] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import pika>>> connection = pika.BlockingConnection(pika.ConnectionParameters(...         host='localhost'))Traceback (most recent call last):  File "<stdin>", line 2, in <module>  File "/home/hawk/g/f3/lib/python3.3/site-packages/pika/connection.py", line 361, in __init__    if host and self._validate_host(host):  File "/home/hawk/g/f3/lib/python3.3/site-packages/pika/connection.py", line 207, in _validate_host    if not isinstance(host, basestring):NameError: global name 'basestring' is not defined

web开发 flask、sqlalchemy 等等都是使用python3，总不至于再回到2.7吧？

if not isinstance(host, basestring):

NameError: global name 'basestring' is not defined

说明basestring 不存在， 你需要import 进来或者定义这个变量
如 a="test"
if not isinstance(a, str): #str 是类型的类型， 所以不用导入， 如果不是就需要导入这个类或者方法
print "不是字符串类型"
else:
print "这个是字符串类型"

python3 里已经没有basestring 类型了，你可以做转换啊。请参考这个http://woodpecker.org.cn/diveintopython3/porting-code-to-python-3-with-2to3.html
