Though not standard, you might encounter:

A home automation hub might store all automation rules in a py3esourcezip file on a USB drive. To update rules, you simply replace one file, not a directory tree. 4. How to Open, Extract, and Inspect a py3esourcezip File Assuming you have a file named application.py3esourcezip (or simply any zip with this internal structure), here is how to work with it. Method 1: Using Standard unzip (Command Line) # Extract to a folder unzip application.py3esourcezip -d py3_source_extracted/ List contents without extracting unzip -l application.py3esourcezip Archive: application

Use py3esourcezip when you need full control over the import mechanism and want to avoid installation. For public libraries, use wheels. 8. Best Practices for Creating Your Own py3esourcezip If you decide to adopt this pattern, follow these steps to create a robust, importable zip. Step-by-step script (Linux/macOS/WSL) #!/bin/bash # Build script for py3esourcezip ZIP_NAME="myapp_v1.0_py3esourcezip" WORK_DIR="build_src" 1. Prepare directory structure mkdir -p $WORK_DIR/mypackage mkdir -p $WORK_DIR/resources 2. Copy source code cp -r ../src/ .py $WORK_DIR/ cp -r ../src/mypackage/ .py $WORK_DIR/mypackage/ cp config.yaml $WORK_DIR/resources/ 3. (Optional) Add main .py for direct execution echo "from mypackage.main import run; run()" > $WORK_DIR/ main .py 4. Create the archive with consistent timestamps (reproducible build) cd $WORK_DIR find . -name " .py" -exec touch -t 202501010000 {} ; zip -r -X ../$ZIP_NAME.zip . -x " .pyc" -x " pycache /*" cd .. For public libraries, use wheels

If a PyInstaller app crashes, the error log might reference a file path like: /tmp/_MEI12345/py3esourcezip/mymodule.py This indicates the runtime extracted your source bundle to a temporary directory named py3esourcezip . Scenario B: AWS Lambda and Serverless Deployments AWS Lambda allows uploading a deployment package as a .zip file. To indicate that the bundle is meant for Python 3.9+ and includes source code (not just dependencies), a smart CI/CD pipeline might name the artifact: my_lambda_py3esourcezip.zip
