alexlib 0.0.6

Making Python even more convenient by extending list and dict and pathlib and more.

Welcome to alexlib

This package extends many native Python classes to equip you with an uneasy-to-tame power. Beside many minor extensions, the major classes extended are:

• list is extended to List

  • Forget that for loops exist in your life, because with this class, for loops are implicitly applied to all items.

• dict is extended to Struct.

  • Combines the power of dot notation like classes and key access like dictionaries.

• pathlib is extended to P

  • P objects are increbily powerful for parsing paths, no more than one line of code is required to do any operation.

* Some other classes that make honorable mention here are `Read` and `Save` classes. Together with `P`, they provide comprehensible support for file management. Life cannot get easier with those.

Furthermore, those classes are inextericably connected. Example, globbing a path P object returns a List object. You can move back and forth between List and Struct with one method, and so on.

You can read the details in the code to grapple the motivation and the philosophy behind its implementation mechanics. Fill your life with one-liners, take your code to artistic level of brevity and readability while simulataneously being more productive by typing less boilerplate lines of code that are needless to say.

Install

just do this in your command line pip install alexlib.

Worry NOT about your virenv, this package installs itself peacefully, never interfere with your other packages, not requires anything with force. If you do not have numpy, matplotlib and pandas, it simply throws ImportError at runtime, that's it. The package is not fussy about versions either.

Getting Started

That's as easy as taking candy from a baby; whenever you start a Python file, preface it with following in order to unleash the library:

import alexlib.toolbox as tb

A Taste of Power

Suppose you want to know how many lines of code in your repository. The procedure is to glob all .py files recursively, read string code, split each one of them by lines, count the lines, add up everything from all strings of code.

To achieve this, all you need is an imminently readable one-liner.

tb.P.cwd().myglob("*.py", r=True).read_text().split('\n').apply(len).np.sum()

How does this make perfect sense?

• myglob returns List of P path objects
• read_text is a P method, but it is being run against List object. Behind the scenes, responsible black magic fails to find such a method in List and realizes it is a method of items inside the list, so it runs it against them and thus read all files and containerize them in another List object and returns it.
• Similar story applies to split which is a method of strings in Python.
• Next, apply is a method of List. Sure enough, it lives up to its apt name and applies the passed function len to all items in the list and returns another List object that contains the results.
• .np converts List to numpy array, then .sum is a method of numpy, which gives the final result.

Other use cases

Invitably in life, you will encounter objects of the same type and you will be struggling to get a tough grab on them. List is a powerful structure that put at your disposal a grip, so tough, that the objects you have at hand start behaving like one object.

This is the power of implicit for loops. Share with us your one-liner snippets to add it to use-cases of this package.
