Debugging Python in VSCode

Learning Python

Automate the Boring Stuff with Python: This shows what you can do with python. Checkout the table of contents and skip around if you already know the basics.
Python Data Science Handbook: I suggest looking through this only if you have a project requiring data processing.

Python Environments

Python Environments: “venv (for Python 3) and virtualenv (for Python 2) allow you to manage separate package installations for different projects.”

Python Requirements.txt

To easily install program requirements on other computers, create a requirements.txt. Rather than manually installing program requirements, you could just run one command to install all program requirements with a requirements.txt

Why and How to make a Requirements.txt

Create a requirements.txt

$ pip freeze > requirements.txt

Use a requirements.txt

$ pip install -r requirements.txt

PyInstaller

Used to make executable files into standalone executable files. This is the preferred way to make python executables.

Note: the files are not 100% stand alone as they are still dependent on some core operating system libraries (for example, on linux to run the executable it’s dependent on glibc library).

To make a full standalone, you could create a pyinstaller executable then use CXFreeze.

pip: PyInstaller: pyinstaller using pip (a package manager)
PyInstaller Official Website: Main home page

Deploying code to servers or other computers

The approach I advocate for is to create a Docker Environment with the program then move the Docker environment to different systems. DockerContainers
One approach is to copy the python program over then install dependencies used onto the computer
One approach is to create a stand alone executable
