By default pip will install packages from the Python Package Index < You can browse the Python Package Index by going to it in your web browser.\n\npip has a number of subcommands: \"install\", \"uninstall\", \"freeze\", etc. (Consult the installing-index guide for complete documentation for pip.)\n\nYou can install the latest version of a package by specifying a package's name\n\nBounded code example (external data; do not execute automatically):\n```console\n(tutorial-env) $ python -m pip install novas\nCollecting novas\nDownloading novas-3.1.1.3.tar.gz (136kB)\nInstalling collected packages: novas\nRunning setup.py install for novas\nSuccessfully installed novas-3.1.1.3\n```\n\nYou can also install a specific version of a package by giving the package name followed by == and the version number\n\nBounded code example (external data; do not execute automatically):\n```console\n(tutorial-env) $ python -m pip install requests==2.6.0\nCollecting requests==2.6.0\nUsing cached requests-2.6.0-py2.py3-none-any.whl\nInstalling collected packages: requests\nSuccessfully installed requests-2.6.0\n```\n\nIf you re-run this command, pip will notice that the requested version is already installed and do nothing. You can supply a different version number to get that version, or you can run python -m pip install --upgrade to upgrade the package to the latest version\n\nBounded code example (external data; do not execute automatically):\n```console\n(tutorial-env) $ python -m pip install --upgrade requests\nCollecting requests\nInstalling collected packages: requests\nFound existing installation: requests 2.6.0\nUninstalling requests-2.6.0:\nSuccessfully uninstalled requests-2.6.0\nSuccessfully installed requests-2.7.0\n```\n\npython -m pip uninstall followed by one or more package names will remove the packages from the virtual environment.\n\npython -m pip show will display information about a particular package\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
