Due to the simplicity, readability, and extensibility of the Python language, the use of Python for scientific computing is increasing, and some well-known universities have adopted Python to teach programming courses. Python is a completely object-oriented language. Functions, modules, Numbers, strings are objects. And fully support inheritance, overload, derivation, multiple inheritance, beneficial to enhance the reuse of source code. In the age of artificial intelligence, Python language is becoming more and more important. In this lecture, we will introduce relevant knowledge of Python.Some source code and the results will be showed during the lecture.
