The standard library includes a wide selection of useful modules for a great variety of uses. These are included in your default Python installation.
- [Instructor] The Python Standard Library includes…a wide selection of modules available for your use…in a standard Python installation.…If we scroll down here you see,…this is the whole library so it also includes functions,…and classes, and all kinds of things;…but starting in section six, these are all modules.…And for example,…here's the documentation for the sys module,…and this is system-specific parameters and functions.…
And so you have many, many things you can do.…So let's take a look at how this works.…Here in Komodo I've opened a working copy of modules.py…from chapter 14 of the exercise files…and you notice the import statement,…that's where I import a module,…and then I use a module like this just as any other object.…I say sys dot and version_info is an element…inside of the class of the module…and version_info returns a collection of information,…and so I can use it with an asterisk here…and it will give me a list of parameters,…and in this case the list of three for the…major, minor, and minor parts of the Python version number.…
