Python operation Kafka reports an error: return ‘& lt; SimpleProducer batch=%s>’ %self.async

return ‘< SimpleProducer batch=%s>’ % self. async
^^^^^
SyntaxError: invalid syntax

reason:

Because PY3 Async has become a keyword in 7. This leads to incompatibility.

Solution:

Method 1:

The latest Kafka version is used, but the Kafka on pypi has not been replaced with the latest one. You can upgrade Kafka Python using the following method
PIP install Kafka python

Method 2:

Just switch to version 3.6 and wait for subsequent upgrades
