Is p language python?

P language is a programming language jointly developed by Microsoft, University of California, Berkeley, and Imperial College London. It has strong advantages in handling concurrency, failover, etc. This article introduces the origin, characteristics and usage scenarios of the P language.

The complexity of emerging applications requires emerging methods to be understood before they can be built, tested, and debugged efficiently. Today's applications often use cloud resources, employ artificial intelligence technology, and are embedded in physical devices. The combination of these three factors makes software development very difficult.

Generally speaking, these modern applications are asynchronous, mainly in the following ways: In order to improve performance, the requester can continue to perform subsequent operations before the current operation is completed. Asynchrony inevitably creates concurrency and brings with it some notorious pitfalls, such as race conditions and Heisenberg bugs (software bugs, usually related to timing, but which may disappear while the cause is investigated, which is Because the current environment has changed). To address the challenges posed by asynchronous computing, we developed P, a programming language for modeling and formulating protocols in asynchronous event-driven applications. The project is a collaboration between Microsoft developers and academic researchers from the University of California, Berkeley, and Imperial College London.

P programmers write protocols at the upper level and its specifications. The P compiler provides automated testing for race conditions and executable programs carrying specified protocols. P provides first-class support for modeling concurrency, specifying safety and liveness properties, and systematically searching and checking that programs meet their specifications. For these functions, P is similar to Leslie Lamport's TLA and Gerard Holzmann's SPIN. But unlike TLA and SPIN, P programs can also be compiled into executable C code. This capability serves as a bridge between high-level models and low-level implementations, and also makes it easier for programmers to accept formal modeling models and specifications.

python language

Python is a computer programming language. It is an object-oriented dynamic type language that was originally designed for writing automated scripts (shells). With the continuous updates of the version and the addition of new language features, it is increasingly used for the development of independent and large-scale projects.
