Python site

There are two types of site-packages directories, global and per user. • Global site-packages (" sys.path when you run: python -m site For a more concise list run getsitepackages from the python -c 'import site; print(site.getsitepackages())' Caution: In virtual environments virtualenv, sys.path from above will list the virtualenv's site-packages directory correctly, though. In Python 3, you may use the python3 -c 'import sysconfig; print(sysconfig.get_paths()["purelib"])' • The per user site-packages directory ( python -m site --user-site If this points to a non-existing directory check the exit status of Python and see python -m site --help for explanations. Hint: Running pip list --user or pip freeze --user gives you a list of all installed per user site-packages. Practical Tips • .__path__ lets you identify the location(s) of a specific package: ( $ python -c "import setuptools as _; print(_.__path__)" ['/usr/lib/python2.7/dist-packages/setuptools'] • .__file__ lets you identify the location of a specific module: ( $ python3 -c "import os as _; print(_.__file__)" /usr/lib/python3.6/os.py • Run pip show to show Debian-style package information: $ pip show pytest Name: pytest Version: 3.8.2 Summary: pytest: simple powerful testing with Python Home-page: https://docs.pytest.org/en/latest/ Author: Holger Krekel, Bruno Oliveira, Ronny Pfannschmidt, Floris Bruynooghe, Brianna Laugher, Florian Bruhin and others Author-email: None License: MIT license Location: /home/peter/.l...

Automate the Boring Stuff with Python By Al Sweigart. Over 500,000 copies sold. "The best part of programming is the triumph of seeing the machine do something useful. Automate the Boring Stuff with Python frames all of programming as these small triumphs; it makes the boring fun." - "I'm having a lot of fun breaking things and then putting them back together, and just remembering the joy of turning a set of instructions into something useful and fun, like I did when I was a kid." - Practical Programming for Total Beginners If you've ever spent hours renaming files or updating hundreds of spreadsheet cells, you know how tedious tasks like these can be. But what if you could have your computer do them for you? In • Search for text in a file or across multiple files • Create, update, move, and rename files and folders • Search the Web and download online content • Update and format data in Excel spreadsheets of any size • Split, merge, watermark, and encrypt PDFs • Send reminder emails and text notifications • Fill out online forms Step-by-step instructions walk you through each program, and practice projects at the end of each chapter challenge you to improve those programs and use your newfound skills to automate similar tasks. Don't spend your time doing work a well-trained monkey could do. Even if you've never written a line of code, you can make your computer do the grunt work.

site-packages is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install), you will find the installed modules in site-packages by default. There are standard locations: • Unix (pure) 1: prefix/lib/pythonX.Y/site-packages • Unix (non-pure): exec-prefix/lib/pythonX.Y/site-packages • Windows: prefix\Lib\site-packages 1 Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well. site-packages is by default part of the Python search path, so modules installed there can be imported easily afterwards. Useful reading • • When you use --user option with pip, the package gets installed in user's folder instead of global folder and you won't need to run pip command with admin privileges. The location of user's packages folder can be found using: python -m site --user-site This will print something like: C:\Users\%USERNAME%\AppData\Roaming\Python\Python35\site-packages When you don't use --user option with pip, the package gets installed in global folder given by: python -c "import site; print(site.getsitepackages())" This will print something like: ['C:\\Program Files\\Anaconda3', 'C:\\Program Files\\Anaconda3\\lib\\site-packages' Note: Above printed values are for On Windows 10 with Anaconda 4.x installed with defaults. site-packages is just the location where Python installs its modules.

os — Miscellaneous operating system interfaces Source code: This module provides a portable way of using operating system dependent functionality. If you just want to read or write a file see open(), if you want to manipulate paths, see the os.path module, and if you want to read all the lines in all the files on the command line see the fileinput module. For creating temporary files and directories see the tempfile module, and for high-level file and directory handling see the shutil module. Notes on the availability of these functions: • The design of all built-in operating system dependent modules of Python is such that as long as the same functionality is available, it uses the same interface; for example, the function os.stat(path) returns stat information about path in the same format (which happens to have originated with the POSIX interface). • Extensions peculiar to a particular operating system are also available through the os module, but using them is of course a threat to portability. • All functions accepting path or file names accept both bytes and string objects, and result in an object of the same type, if a path or file name is returned. • On VxWorks, os.popen, os.fork, os.execv and os.spawn*p* are not supported. • On WebAssembly platforms wasm32-emscripten and wasm32-wasi, large parts of the os module are not available or behave differently. API related to processes (e.g. fork(), execve()), signals (e.g. kill(), wait()), and resources (e.g. nice()) are n...
