Start: 19/10/2018
End: ??/??/????

19/10/2018:
1. Added the first pdf: Introduction to Python

Python Introduction.pdf

I don't even program in Python, but for me, the latest installation only made problems.
I only needed it for emscripten which comes with a lot of batch files which want to call the right python script and .. it never works xD
Typing python results in Command not found. Even pip is not available.
I'd to rewrite every batch script that it use py instead of python and py -m pip instead of pip.
Then everything worked fine.

Sometimes for example i had to add to every print the brackets, because in the version i had they were necessary.

What do u mean "python can cause a lot of problems"?
U can still use python2 instead of python3.What kind of logic is this?

i don't know what is to laught on this
This concept is a NoGo
If C++ wouldn't be compatible anymore with C it would have failed the Concept
I also can compile very old Turbo Pascal Code with modern Objective Pascal
And JavaScript 1.0 (from 1995) written Code will still work on ECMAScript 2017
To know that Python 3.X is not compatible to 2.X means, they are different Programming Languages and not an Update
It's sounds for me more like C# and VB.NET. Its the same Engine with different Syntax

In AHK (AutoHotkeys) is a good Counter example, because Lexikos made a much more mightier and dynamic AHK out of AHK
But he broke some syntax from the old one by it, what meaned that is not fully Compatible anymore and it also meaned, it can not replace AHK and thats why it become AHK_L

The first looks better imo because its more similar with Java/C.How does this change breaks any syntax?
Also,u can run any script with typing python2 or python3 ,so noone forces u to make changes into any script.
Noone forces u to rewrite any script from 2 to 3

Also,with a simple google search https://www.geeksforgeeks.org/write-...nt-compiler-c/

Thats why,it is OMEGALUL

the half of the exmaples what compiles in C and not in C++ is a bad joke. To name a variable name to a reserved name in the upgraded version is no conception break and to can define functions later then used is also a bad concept even in C. It may works and not works anymore in C++, but it's not an issue at all.
And most we talk about "bad stuff" which compiled in C and not in C++ anymore, like define a constant without defining a constant.. what is the use practise on it?
to make a difference between print "Hello World" and print("Hello World") is not important, because if it's like in perl where both of it works. But if 1) works in py 2.0 and 2) in py 3.0 then they are different languages and it's not an upgrade

Thanks you very much
