Python 3.7

Python 3.7:

Python 3.7 is a version of the Python programming language released on June 27, 2018. It introduced several new features and improvements over previous versions.

Here are some notable features of Python 3.7:

Data Classes: Python 3.7 introduced the dataclass decorator, which allows you to easily define classes that are primarily used to store data. It automatically generates special methods like __init__, __repr__, and __eq__, reducing the amount of boilerplate code required.

Type Hints: Python 3.7 expanded the capabilities of type hinting, allowing you to provide more precise type information in function signatures and variable annotations. This helps with static analysis and code documentation.

Context Variables: The contextvars module was introduced in Python 3.7, providing a way to manage context-specific data within a task or execution context. It allows for better handling of asynchronous programming and thread-local storage.

Speed Improvements: Python 3.7 introduced various performance optimizations, such as faster attribute access, optimized built-in functions, and improved dictionary ordering. These optimizations improved the execution speed of Python programs.

Built-in Breakpoint: Python 3.7 introduced a new built-in function called breakpoint(). It provides a standardized way to enter the debugger at a specific line of code, making it easier to debug programs.

Improved Syntax Warnings: Python 3.7 introduced more precise and helpful syntax warnings, making it easier to identify and fix potential issues in your code.
