PyArmor supports Python 2.6, 2.7 and Python 3. PyArmor is tested against Windows, Mac OS X, and Linux. PyArmor has been used successfully with FreeBSD and embedded platform such as Raspberry Pi, Banana PyArmor Documentation, Release 6.4.0 pyarmor obfuscate --platform linux.armv7 foo.py # For project pyarmor build --platform linux.armv7 3.5.1 Obfuscating scripts with different features There may obfuscate --platform linux.x86_64.7 foo.py Note that the dynamic library with different features aren’t compatible. For example, try to obfuscate the scripts with --platform linux.arm.0 in Windows: pyarmor

source package management system and environment management system that runs on Windows, macOS and Linux. Conda quickly installs, runs and updates packages and their dependencies. Conda easily creates, saves ROOT_DIR The directory that Anaconda or Miniconda was installed into. EXAMPLES: /opt/Anaconda #Linux C:\Anaconda #Windows /pkgs Also referred to as PKGS_DIR. This directory contains decompressed packages with command line commands at the Anaconda Prompt for Windows, or in a Terminal window for macOS or Linux. This 20-minute guide to getting started with conda lets you try out the major features of conda
