ProgrammingLanguage

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 …).

History of Python

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.

Code sample (Syntax)

Code sample (Syntax)

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.

Enough to Understand the Code

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.

White Spaces

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

Python vs PHP

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.
