The development environment: Python3.5
Python 3.5 is a version of the Python programming language released in September 2015. It is a further development of Python 3, which was first released in December 2008 and has many improvements over Python 2. In terms of web development, there are some important differences between Python 3.5 and Python 3: Speed: Python 3.5 includes several optimisations that improve the speed of Python applications. In particular, Python 3.5 includes a new implementation of the generator that is up to 40% faster than the previous implementation. Asynchronous programming: Python 3.5 supports asynchronous programming, which allows developers to write efficient web applications that can handle many concurrent connections. New libraries: Python 3.5 includes several new libraries that can be useful for web development, such as the "typing" module that supports type annotations. Improved error handling: Python 3.5 provides improved error handling features that help to quickly identify and fix errors in web applications. New syntax: Python 3.5 adds new syntax features that can improve the readability of web applications. One example is the use of the @ operator for matrix multiplication.
