All python and pip commands throwing syntax error

问题:

Redis is imported as -

import redis

Redis When I try running the script -

python -

import redis
  File "/usr/lib/python2.6/site-packages/redis/__init__.py", line 1, in <module>
    from redis.client import Redis, StrictRedis
  File "/usr/lib/python2.6/site-packages/redis/client.py", line 3198
    return {decode(encode(k)): v for k, v in iteritems(data)}

Then I found that even running any pip command, I am getting the same error -

sudo pip uninstall pip
