Missing six package dependency from requirements.txt

[asaschachar]

The Python SDK uses the package six but does not appear to require it in any of the requirements

[amilstead]

Looks like the probable right version to use would be either six>=1.4.1 (to match cryptography) or six>=1.5.2, (to match PyOpenSSL), mostly to be courteous to upstream deps.

If not, you could always just use >=1.12.0, since that's the most recent version of six and satisfies existing dependencies.

From pipdeptree:

$ pipdeptree --reverse --packages optimizely-sdk,six
optimizely-sdk==3.1.0
six==1.12.0
  - cryptography==2.6.1 [requires: six>=1.4.1]
    - pyOpenSSL==19.0.0 [requires: cryptography>=2.3]
  - mock==1.3.0 [requires: six>=1.7]
  - pyOpenSSL==19.0.0 [requires: six>=1.5.2]
  - python-coveralls==2.7.0 [requires: six]
  - python-dateutil==2.7.5 [requires: six>=1.5]
    - botocore==1.12.62 [requires: python-dateutil>=2.1,<3.0.0]
      - awscli==1.16.72 [requires: botocore==1.12.62]
      - s3transfer==0.1.13 [requires: botocore>=1.3.0,<2.0.0]
        - awscli==1.16.72 [requires: s3transfer>=0.1.12,<0.2.0]
