... One of the most important advantages of Python 2 is that it has a large number of third-party libraries that can be used to do anything, but Python 3 doesn't have that advantage. Admittedly, there are a lot of libraries that have been ported to Python 3, but there are more libraries that are not ported or easy to migrate. For example, you need to parse X, but

Python learning diary (second week), second week of python I have officially learned the Python language since this week. I will share with you an article on learning Python every week! PythonInstallation The first step of learning is to have a runtime environment. So next we will introduce the installation steps. On t

Python memory management method and garbage collection algorithm parsing, python garbage collection Summary There is a circular reference problem in the list, tuples, instances, classes, dictionaries, and functions. Instances with the _ del _ method will be processed in a sound way. It is easy to add GC support for new types. Python that supports GC is Binary com

Let's talk about the strings and character encoding in Python (recommended) and python strings. Content of this section: 1. Preface 2. Related Concepts 3. default encoding in Python 4. Support for strings in Python2 and Python3 5. character encoding and conversion I. Preface Character encoding in Python is a common top

Main methodCompile it into a byte codeSince the byte code cannot be run directly, you need to write a little bat or bash script to run it.Of course, the same work can be done in C + +. But C + + is not a cross-platform language. In this simple enough example, it may not be possible to see the difference between C + + and Java implementations, but in some more complex scenarios, For example, to record connectivity or not information to the network database. Because Linux and Windows have differe

PY is the source file, PYc is the source file compiled file, Pyo is the source file optimization compiled file, PYD is written in other languages of the Python library1. Is python an interpreted language?Python is an explanatory language, and I've been believing it until I find out the existence of the *.pyc file.If it is an interpreted language, what is the gene
