Enables local Python and local Python package installation.
Settings
--------
This module supports virtual environments from conda and virtualenvwrapper. By default, only virtualenvwrapper is enabled. To disable virtualenvwrapper, add the following to *zpreztorc*.
zstyle ':prezto:module:python' skip-virtualenvwrapper-init 'on'
Conda support is enabled by adding the following to *zpreztorc*.
zstyle ':prezto:module:python' conda-init 'on'
Caution: using conda and virtualenvwrapper at the same time may cause conflicts.
