PythonStarterPackage 0.4.4

Python Starter Package
This is a basic python starter package to be used as a template for creating your own python packages. See "PythonStarterPackage Setup Guide.md" in doc/ for a detailed explanation of the package resources.

Github repo: https://github.com/MysticTechnology/PythonStarterPackage
PyPi: https://pypi.org/project/PythonStarterPackage/

Prerequisites
For Windows, it is recommended to run this app on a Linux emulation layer such as the Git Bash terminal. See the "Instructions for Git Bash" section for details. In addition to Git Bash, make sure you also have Python3 and Pip3 as described below.
For Mac and Linux, this app should work out of the box on the Linux or Mac terminal, but make sure you also have Python3 and Pip3 as described below.
Requirements:

Python3 (version 3.8 or greater) - Install Python3 here: [https://www.python.org/downloads/]. Check version with: python3 --version.
Pip3 (version 20.2.1 or greater) - Make sure to install python3-pip in order to use pip install. Check version with: pip3 --version.

Installation
There are a couple of options to install this app:

Pip Install - This app is hosted on PyPi and can be installed with the following command:

pip3 install PythonStarterPackage


Local Install - Alternatively, you can download or git clone the Github repo and install it locally with the following:

git clone https://github.com/MysticTechnology/PythonStarterPackage.git
cd PythonStarterPackage
pip3 install -e .

To uninstall this app:
pip3 uninstall PythonStarterPackage


If you used the local install option, you will also want to delete the .egg-info file located in the src/ directory of the package. This gets created automatically with pip3 install -e ..

Usage
After installation, you have a couple ways to run this app.

Run this app from the terminal with this command:

pythonstarterpackage


Run this app with the python command python3 -m:

python3 -m pythonstarterpackage


You can also import the package resources and run them in your own project:

from pythonstarterpackage import *
starter = StarterPkg()
starter.run()

Documentation
The purpose of this project is to show you how to create a standard python package from scratch. This project is inspired by this excellent getmyip package by @iamtennislover: [https://github.com/iamtennislover/getmyip] and this great guide on deploying python packages by @sigma-coding: [https://github.com/areed1192/sigma-coding].
Setup
See "PythonStarterPackage Setup Guide.md" in doc/ for a detailed walkthrough of what each of the package resources do. Once you have an understanding of this package, you can clone this package to your local directory and proceed to testing and deployment.
Testing
In the directory containing the setup.py file, you can test the package by installing it in pip3 editable mode. This will allow you make changes to it and test it without having to push the changes each time.

Use pip3 to install the package in editable mode:

pip3 install -e .


Run the package by calling the package directly:

pythonstarterpackage

Or use python3 -m:
python3 -m pythonstarterpackage


Testing the import. Run the test_main.py file:

python3 ./test/test_main.py


Once finished, delete the pythonstarterpackage.egg-info file and uninstall the package with:

pip3 uninstall PythonStarterPackage

Note: It is recommended that you use a virtual environment when testing your package.

To create a virtual environment:

virtualenv venv


Activate the environment use: . venv/bin/activate. On Windows it may be: . venv/Script/activate.

Dependency Mapping
Next, make sure to check the package dependencies and update the setup.cfg file as needed. To do this:

Create (or overwrite) the requirements.txt document with pipreqs. This is an extremely useful tool because it automatically finds all of the relevant versions of dependencies your package relies on and puts them into the requirements.txt file. If you don't have pipreqs, install it with pip install pipreqs.

pipreqs --force --encoding utf-8


Once the requirements.txt is updated, check to see if there is any additional dependencies that need to be added or updated in setup.cfg under the install_requires =. If so, add or update it.

Deployment
Once the package is ready, we can work on deploying the package.

Upgrade setuptools, wheel, and twine (twine will be used in the next part).

pip3 install --upgrade setuptools wheel twine


Build the package with setup.py.

python3 setup.py sdist bdist_wheel


Check the contents of the .whl and .tar.gz distributions. The key things to look for are: (1) all of your package subdirectories like utils are added to both distributions, (2) your config and package data are included in both distributions.

unzip -l dist/*.whl && tar --list -f dist/*.tar.gz


Test a local install of the package and run it to make sure it is working.

pip3 install .
pythonstarterpackage


After testing that it is working, uninstall the package from pip3.

pip3 uninstall pythonstarterpackage

If there are any issues in the above you can always uninstall the package and delete the distributions then proceed to troubleshoot the issue. Once complete start over from the beginning. The commands below allows you to delete the distributions.
rm -rf build dist src/*.egg-info

BE CAREFUL not to miss copy the above command, as if you delete something you didn't intend you will not be able to retrieve.
Upload to PyPi
In order to upload to PyPi make sure to setup your PyPi account first. See "PyPi Setup Guide.md" in doc/ for more details. You will also need to have twine installed and upgraded. Once you have all of this setup do the following:

Upload using twine.

twine upload dist/*


Install your package with pip.

pip3 install pythonstarterpackage

Note: If you get a "Requirements already satisfied..." for pythonstarterpackage when trying to install, it may be because pip still thinks you have the package already installed from the testing earlier. To cleanly break that connection, simply delete the ./src/PythonStarterPackage.egg-info. Then try uninstalling and reinstalling again.

Finally, run the app with: pythonstarterpackage.
Uninstall with: pip3 uninstall pythonstarterpackage.

Troubleshooting
This section goes over some of the common issues found and how to resolve them.
"Command Not Found" Error When Running the App
On Linux, if you are getting a command not found error when trying to run the app, you may need to add ~/.local/bin/ to PATH. See this thread for details: [https://stackoverflow.com/a/34947489]. To add ~/.local/bin/ to PATH do the following:

Add export PATH=~/.local/bin:$PATH to ~/.bash_profile.

echo export PATH=~/.local/bin:$PATH > ~/.bash_profile


Execute command.

source ~/.bash_profile

"ImportError: No module named 'tkinter'
Your python version is probably missing tkinter which typically comes default. See this post for details [https://stackoverflow.com/a/25905642]. Install it with the following:
sudo apt-get install python3-tk

For Mac, use this:
brew install python-tk

Instructions for Git Bash
For Windows, it is recommended to run this app on a linux emulation layer like the Git Bash terminal. Here are the instructions for installing and setting up Git Bash:

Go to https://git-scm.com/downloads and click download.

Version >= 2.34.1


During the installation setup, make sure to include OpenSSH. Recommenced setting should be fine:

Use bundled OpenSSH - This uses ssh.exe that comes with Git.


Leave the other settings as default, click through, and install.
Open bash.exe and install Python3 https://www.python.org/downloads/
Proceed to the "Installation" section to install this app.

IMPORTANT: For Windows, use the bash.exe terminal rather git-bash.exe. There is a known issue with git-bash.exe messing up Python os commands in import os. See this thread for details: [https://stackoverflow.com/a/33623136].

You can find bash.exe Git folder in the bin/ directory. For example: If git-bash.exe is here C:\Program Files\Git\git-bash.exe then you should find bash.exe here C:\Program Files\Git\bin\bash.exe.
