The development environment: Python3
Python 3 is the latest version of the Python programming language, released in December 2008, and is a significant update over Python 2. It is one of the most widely used programming languages for web development and has many advantages over Python 2. In the area of web development, there are some important differences between Python 3 and Python 2: Unicode support: in Python 3, Unicode support is treated as standard. This means that strings in Python 3 are Unicode strings by default, whereas in Python 2 they are treated as ASCII strings. This makes processing text in different languages much easier. Improved syntax: Python 3 offers improved syntax over Python 2, including the ability to specify arguments by name and enhanced support for lists and dictionaries. Deprecated functions: Python 3 removes some deprecated functions that were still available in Python 2. This can cause some difficulties when updating older code, but ultimately results in code that is faster, more stable and easier to maintain. Speed: Python 3 generally offers better speed than Python 2, especially when processing text. New libraries: Python 3 offers many new libraries specifically designed for web development, such as Requests for HTTP client support and Flask for web application development.
