The evolution of the operating system and Python

The development history of the operating system:

Operating system: What is an operating system? The first thing we think about is the computer, the so-called Windows8,windows7, or the XP system and the WINDOWS10, and of course the Android system of our mobile phone or the iOS system of the iphone, but is there a specific definition? The operating system (English: Operating system, or OS) is a computer program that manages and controls computer hardware and software resources, is the most basic system software that runs directly on "bare metal", and any other software must be run with the support of the operating system. Our mobile phone is constantly upgrading, then the system certainly is, so let us briefly review the history of the operating system.

1. Before the 1980 's, the first computer did not have the operating system, all by manual operation to achieve, so, in 1947, the appearance of transistors and Morris Vincent Wilkes invented the micro-program method, make the system management tools and procedures become the basis of the operating system, free from the era of manual operation.

In the early 2.196 years, a batch processing system appeared in 1936, Os/360 appeared in 1963, the singular company cooperated with Bell Labs to build Multics in pl/i language, which was the source of the excitation Unix, but later rewritten, 80, The advent of MS-DOS is the most common operating system, while the 1980 's another rise in operating system XOR is Mac OS,

3. In the 1990s, Apple I computer, the first generation of Apple Computer products turned out, MacOS operation has been a great success, at the same time, Microsoft's response to the more powerful operating system is the launch of Windows NT in 1993, as well as the various upgrades later, until now, The choice of personal computers has been confined to the Windows family, the Unix-like family and Linux, and Linux and Mac OS X as the main alternative,

Python's history:

For beginners (without foundation), what is Python, completely unaware, knows that it is a programming language without a system concept, but what exactly is Python, after internet access and teacher's explanation I am here to briefly explain my understanding, Python (KK English pronunciation:/?pa ? θ?n/) is an object-oriented, literal translation computer programming language. is also a powerful and perfect general-purpose language, has more than 10 years of development history, mature and stable. Python has the richest and most powerful class library in the scripting language, enough to support most everyday applications. Python syntax is simple and clear, with a rich and powerful class library. It is often nicknamed the Glue language, which makes it easy to easily connect a variety of modules (especially C + +) made in other languages.

The origin of the 1.Python, the founder of Python for Guido van Rossum. During the Christmas of 1989, in Amsterdam, Guido was determined to develop a new script interpreter as an inheritance of the ABC language in order to get rid of the boredom of Christmas. Python was chosen as the name of the program because he was a fan of the comedy community called Monty Python.

The birth of the 2.Python: 1991, the first Python compiler (also an interpreter) was born. It is implemented in C and is capable of invoking C libraries (. so files).    From birth, Python already has: class, function, exception handling (exception), core data types including tables (list) and dictionaries (dictionary), and module-based extension systems. The original Pythonlogo: Designed by Guido's brother Justvon Rossum,

Today Python has entered the age of 3.0. Since Python3.0 is backwards incompatible, transitions from 2.0 to 3.0 are not easy. On the other hand, Python's performance is still worth improving, Python's computing performance is lower than C + + and Java (see Google's discussion). Python is still a developing language. I look forward to seeing the future of Python.

3. Current status of Python:

Python has become increasingly popular with more people, and it is believed to be the most popular programming language.
