Python programming language
1.
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:

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.
