When anaconda, miniconda or other versions of python are installed they automatically add paths to their respective versions of python to the top of the bash profile.īash reads the bash profile in sequential order - from top to bottom - and adds those paths to the PATH in the order that they’re read. You can add a variety of preferences to the bash profile, including modifications to the PATH. The bash profile is a set of instructions that are run by the shell when the user logs in to bash. When the shell finds that command, it stops and calls it even if there is another version of the same command, with the same name, further down in the list. When you ask your shell to run a particular command or run an interpreter, python for example, the shell looks through the different directories listed in the PATH in order they’re presented above. /Library/Frameworks/amework/Versions/3.6/bin./Library/Frameworks/amework/Versions/2.7/bin./Library/Frameworks/amework/Versions/3.7/bin.The directories above are separated by a colon, this is what they look like displayed in sequence: Library/Frameworks/amework/Versions/3.7/bin:/Users/username/anaconda3/bin:/Library/Frameworks/amework/Versions/2.7/bin:/Users/username/miniconda2/bin:/Users/username/miniconda3/bin:/Library/Frameworks/amework/Versions/3.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/X11/bin:/usr/local/git/bin You can display the path on your computer using the echo $PATH command: $ echo $PATH

When searching for solutions to problems, you’ll frequently come across sample code that employs code libraries you’ve never heard of.The path is a list of directories that your shell will look through when you execute a command. These libraries can save you a lot of time coding or make a task (such as creating a CSV file or scraping a webpage) much more manageable. One of the best things about Python is the abundance of excellent code libraries that are publicly and freely available. However, anyone using an older version of Python will equally benefit from this tutorial because the processes are still quite common. Pip is installed by default in Python 3.8 and newer. There are various ways to install external modules, but for the sake of this course, we’ll use pip, which is available for both Mac/Linux and Windows. This tutorial will walk you through the process of downloading and installing Python modules. Setup.py is the build script for setuptools-based packages. The setuptools package is used in the Sample Project: “A setuptools based setup module.” Setup.py [

In addition, we have others like open CV, computer vision, etc. xlwings, on the other hand, allows us to interface with excel. Further, several other packages like matplotlib help us plotting, while Pygame helps develop a graphical user interface and build diverse games. For example, if we want MATLAB-like functionality matrices numerical analysis, you can use numpy, optimizers, and differential equation solvers. One of the reasons that Python is so valuable is that there are several packages that we can install that extend the capabilities of Python. Example: Installing matloplib using pip.Using a local src tree for installation.Additional approaches for Installing modules in Python.Install Python packages for scientific purposes.Installing Python modules in a virtual environment.Using Setup.Py to Install Python Packages.Installation of Python packages manually.
