Python basics and comparing python with PHP and TCL.

2.  Python was conceived in the late 1980s, and
its implementation began in December
1989 by Guido van Rossum .
 first released in 1991.
 Python 2.0 was released on 2000 with new
features like supporting (Unicode …).

3.  Python 3.0 (Python 3000 or py3k) was
released on 3 December 2008.
 The End Of Life date (EOL, sunset date) for
Python 2.7 was initially set at 2015, then
postponed to 2020.

5.  widely used high level programming language
(Massive Community) .
 An interpreted language.
 Open source general-purpose language.
 Object Oriented, Procedural, Functional.
 Great interactive environment.

7.  Web services Applications
 Science (for data science/statistics & machine learning/Deep
learning)
 Embedded systems

8.  Web crawling & scrapping/harvesting
 Scrapping: is HTML/XML parsing technique to obtain data from web
pages in websites that do not provide developer API
Such as Scrapy framework and BeautifulSoup4

11.  Assignment uses = and comparison uses ==.
 For numbers + - * / % are as expected.
 Special use of + for string concatenation.
 Special use of % for string formatting (as with
printf in C)
 Logical operators are words (and, or, not) not
symbols
 The basic printing command is print.
 The first assignment to a variable creates it.
 Variable types don’t need to be declared.
 Python figures out the variable types on its own.

12.  Whitespace is meaningful in Python:
especially indentation and placement of
newlines.
 Use new line to end line of code.
 No braces { } to mark blocks of code in
Python.
 Often a colon appears at the start of a new
block.

16.  I created two lists with same length (1000)
and passed them to bubble sort function in
both (py && tcl) and gives me these results :
1- Python : 00.393000s
2- TCL : 09.928s

17.  Wide comparison between Python and TCL in
this link:

language/vs/python-programming-language
 What is your opinion about this comparison ??

18.  comparing two lists with same length (1000)
and passed them to bubble sort function in
both (py && php) and it gives me these results :
1- Python : 00.393000s.
2- PHP : 00.647000s.

19.  In this link we have wide comparison between
these two programming language.

language/vs/php
 What is your opinion about this comparison ??

20.  it seemed obvious to me that raw language
speed and framework optimization level are
the most important parts to website
performance.
 Then it seems pretty obvious to me that
framework and language speed just don’t
matter in overall application performance and
success.

21.  Load balancer
 Web accelerator
 Web server
 Application server
 The framework
 Cache
 Database
 Architecture impact
