Python3.7 the latest version of the operating instructions, please keep it good!

The following is a translation of the contents of the Python website

It is important to note that this version is currently the third of the four preview versions that Python3.7 is expected to release.

Python Release python 3.7.0b3

Python data classes

Python Generator exception handling

In Python 3.7, after the generator throws an Stopiteration exception, the stopiteration exception is converted to a RuntimeError exception, so it does not silently affect the application's stack frame. This means that some programs that are less sensitive to the behavior of the generator will throw RuntimeError in Python 3.7. In Python 3.6, this behavior generates a deprecated warning; in Python 3.7, it generates a complete error.

Python development model

Python interpreter new command-line switch:-X allows developers to set many low-level options for the interpreter. In Python 3.7, option-X dev enables the development mode, which typically has a significant performance impact, but is useful to developers during debugging.

Python time function with nanosecond resolution

Python UTF-8 Mode

Built-in breakpoint () function

Python comes with a built-in debugger, but it can also be connected to third-party debugging tools as long as they can talk to the Python internal debugging API. However, Python has so far lacked a standardized way to trigger the debugger programmatically from within a Python application.
