Using an M1 MBA. Starting playing with SwiftBar. I ran “Python3 --version” and got the following message. Will this just be some updated tools like Python, Perl, etc? Any clue how much space it will use? I don’t want to grab 40GB of cruft just to run this. 
Thanks!
They provide the entire compilation toolchain for programs running/using Terminal and take up about 3GB of space. I believe Python uses them for compilation (managing pipenv installs, etc.) and the tools installation itself doesn’t provide new versions of scripting languages. Here’s Apple’s summary.
This package enables UNIX-style development via Terminal by installing command line developer tools, as well as macOS SDK frameworks and headers. Many useful tools are included, such as the Apple LLVM compiler, linker, and Make. If you use Xcode, these tools are also embedded within the Xcode IDE.
