Package: pipfromrepl
Pip From REPLUPDATE: This module is unnecessary. I now recommend using the one-linerimport pip; pip.main(['install', 'module_name_here'])module to install modules from the interactive shell rather thanpipfromrepl. This code is easier to remember and works on Python versions 2.7 and 3.5+. The only downside is that it doesn't work on Python 3.4, in which case, use the instructions below. Here in 2023, however, the number of students working from 3.4 is near nonexistent so this is unlikely to be an issue.Pipfromrepl runs pip to install packages from the Python interactive shell aka REPL.If you are leading a programming workshop and want to avoid headaches of running pip from students' machines (with all their possible environment configurations), pipfromrepl provides a single set of instructions to quickly get packages correctly installed.The benefit of pipfromrepl is that the user doesn't need to know how to navigate the command-line or have their PATH environment variables set up. If multiple versions of Python are installed, pipfromrepl uses the pip module associated with the currently running interactive shell. The goal of pipfromrepl is to reduce the number of steps that students and beginners need to take to get Python packages installed on their computer.Pipfromrepl is meant to assist students and instructors. It's probably a good idea to not rely on it in production environments.InstallationTo install pipfromrepl from the REPL, copy and paste the following into the REPL:import subprocess, sys; subprocess.run([sys.executable, '-m', 'pip', 'install', 'pipfromrepl'])Pipfromrepl works on Python 2.7 and Python 3.4+. Linux users may need to install pip separately by runningsudo apt-get install python3-pipfrom a Terminal.Quickstart GuideAfter installing pipfromrepl, runimport pipfromrepl:>>> import pipfromreplCallpipfromrepl.install()to install a package from PyPI:>>> pipfromrepl.install('pymsgbox')
