New implementation(patterns)
So.Basically recently I just faced with some problem. I wanted to create my
own data type. I created new class put something in it. But I really wanted to
set items in it like so:
>>>datatype[0][0][1]=1
As you could see I used 3 keys But magic method __setitem__ alows me only
to do something like this:
===
>>>datatype[0,0,1]=1
===
And that's a little bit uncomortable.
Also...I know that probably everyone sometime wanted to 'hide' class name when
you create object and not to write this:
===
>>>var=MyClass('David')
===
...And instead to write this:
===
>>>var=
>>>var
<__main__.MyClass object at 0x006242B13748>
===
I think that would be much easier and glamourus.
So here I present you special type of object: pattern
Example:
===
>>>&mypattern='<'str'>'
==
Here I created variable that stored pattern
This pattern allows me to write '<>' with string in this
For example from that momemnt if I type ''
Nothing will happen.
Also patterns can have commands in them:
==
>>>&mynewpattern='#'list'#'
>>> def &mynewpattern:
... return MyClass(list)
==
Here I gave pattern 'mynewpattern' functionality. Now it RETURNS CLASS!!!
This way we could make shorter and more beautiful.In the example list is type
of data like string or integer. And now I made that when I type lists with '#'s
program returns class MyClass.
That's concludes explanation of patterns
P.S. Ask me in comments if you didnt understand something.

Python installer
Please help me with Python. I many,MANY TIMES tried to install it, but always had problemThese installers were glistchy. What do I mean? I mean that when I installed Python I almost always got wrong packed folders. For example I open python's folder click on python.exe aand.I just get error that there is no module name 'encodings' but it is just in wrong folder-Lib. When I am trying to organize it, still I get some errors. Yeah python.exe works but tkinter does not imports, plus pip cant launch because of the import errors. And I am really tired of this!!! How can I fully expierence Python if installer installs wrong? How? I am really tired of this. I even checked PC on viruses and malwares, but no this glitch HAPPENS. Pleas help to fix this problem and normally program on Python!!! -- https://mail.python.org/mailman/listinfo/python-list
