PYTHON 3.5

Python 3.5, released in September 2015, introduced several significant features and enhancements to the Python programming language.

Some key aspects of Python 3.5 include:

1. Asyncio Enhancements: Python 3.5 expanded support for asynchronous programming with enhancements to the asyncio module. This release introduced new syntax for defining coroutines (async and await keywords), making it easier to write asynchronous code in Python.

2. Type Hinting: Python 3.5 introduced a standardized syntax for type hints through the typing module. While Python remains dynamically typed, type hints provide a way to annotate function signatures and variable types, improving code readability and maintainability, especially in larger projects.

3. Matrix Multiplication Operator: Python 3.5 introduced the @ operator for matrix multiplication, providing a more concise and readable syntax for matrix operations.

4. Formatted String Literals (F-strings): Python 3.5 introduced formatted string literals, also known as "F-strings." F-strings allow for easier string formatting by embedding Python expressions directly within string literals, improving readability and reducing the need for concatenation or formatting functions.

5. Additional Library Enhancements: Python 3.5 included updates and improvements to various standard library modules, such as enhancements to the zip() function, improvements to the os.scandir() function for directory iteration, and updates to the venv module for creating virtual environments.

6. Performance Improvements: Python 3.5 included optimizations and performance improvements, such as faster startup times for small scripts and reduced memory usage in certain scenarios.

Overall, Python 3.5 represented another step forward in the evolution of the language, introducing features and enhancements that improved productivity, readability, and performance for Python developers.
