The PyPA recommended tool for installing Python packages.

Install PIP for Python 2

Python 2 is not installed by default on Ubuntu 17.10. But if you do need Python 2 for any specific reason, you can install Python 2 on Ubuntu 17.10.
Run the following command to install Python 2 on Ubuntu 17.10:

$ sudo apt-get install python

Press ‘y’ and press <Enter> to continue the installation. It may take a while to download and install everything depending on your internet connection.

Once Python 2 is installed, you can check the version of Python 2 with the following command:

$ python --version

strong@foreverstrong:~$ python --version
Python 2.7.12
strong@foreverstrong:~$ 

You can see that the installed Python 2 version is 2.7.12.
Now to install PIP for Python 2, run the following command:

$ sudo apt-get install python-pip

Press ‘y’ and press <Enter> to continue the installation. It may take a while to download and install everything depending on your internet connection.
Once the installation is complete, you can check the version of PIP for Python 2 using the following command:

$ pip --version

strong@foreverstrong:~$ pip --version
/usr/local/lib/python2.7/dist-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)
pip 18.0 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
strong@foreverstrong:~$ 

You can see that the version of PIP for Python 2 installed is 18.0 and its installed in /usr/local/lib/python2.7/dist-packages/pip system directory. When we update PIP for Python 2, the installed location will change as it did for PIP for Python 3.

Update PIP for Python 2

To update PIP for Python 2, run the following command:

$ pip install -U pip

strong@foreverstrong:~$ pip install -U pip
/usr/local/lib/python2.7/dist-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)

strong@foreverstrong:~$ 

Now check the version of PIP for Python 2 with the following command:

$ pip --version

strong@foreverstrong:~$ pip --version
/usr/local/lib/python2.7/dist-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)
pip 18.0 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
strong@foreverstrong:~$
