Introduction to Python-001

Python founder:

The founder of Python is Guido van Rossum (Guido van Rossum). During the Christmas of 1989, Guido van Rossum to spend time in Amsterdam, determined to develop a new script interpreter, as an inheritance of the ABC language.

The latest Tiobe leaderboards, Python catch up with PHP occupy the four, Python advocating beautiful, clear, simple, is a good and widely used language.

Python's application areas:

1. Cloud computing

2. Web Development

3. Scientific computing, artificial intelligence

4. Financial

5. Graphical GUI

Python Language Description:

1. Python is an explanatory language (languages that do not need to be compiled to run)

2, Python is a dynamic type language (the language of the data type check will be done during run time, do not need to assign data type to any variable)

3.Python is a strongly typed definition language (the language that enforces the data type definition, which is always the data type if the data type of the specified variable is not cast) type-safe language

Summary: Python is a dynamically explanatory strong-type definition language, with many Python interpreters, but the most widely used or CPython

Advantages and disadvantages of Python:

Advantages :

1. Elegant, clear and simple

2. High development Efficiency

3, high-level language (no need to consider the underlying details)

4, the portability is strong

5, the scalability of strong

6, can be embedded strong

Disadvantages:

1, slow (compared to the Java and C language, Python is slower to run, but their previous differences are invisible to the naked eye, most of the time Python has been fully able to meet your program speed requirements)

2. Code cannot be encrypted

3. Threads cannot take advantage of multiple CPUs

The history of Python:

1.features of Python 2.6 and python2.7 compatible python3.x will be supported by 2020

2, the latest version of Python, please refer to the official website: https://www.python.org/downloads/
