Can python replace shell?

Python is a simple and easy-to-learn programming language with powerful functions. Of course, it can be used to replace the shell.

Shell is a program written in C language. It is a bridge for users to use Linux or UNIX-like. (Recommended learning: Python video tutorial)

Shell is both a command language and a programming language. Shell refers to an application that provides an interface through which users access the services of the operating system kernel.

Python's built-in os module provides a very rich method for interacting with the operating system, and you can learn Python's os module in depth.

Python was first used to simplify operation and maintenance workload, and eventually developed into a universal language.

There is no problem in using python to replace the shell. python is easy to learn, has simple syntax, and is faster to learn. You can also use python for automated operation and maintenance.

The functions of shell can be realized by Python, and the amount of code is smaller, the structure is better, and the readability is better. However, the functions that Python can realize may not be realized by Shell. For example, in operation and maintenance, The Socket module used for network communication, the Django framework used for WEB, the psutil module used for performance collection, etc., and the Shell has a strong dependence on the commands of the operating system, which can be avoided to a greater extent by Python.

Using a Shell IDE is a big problem. Although Python’s native IDE is not very good, third-party IDEs are still very powerful, although they are not comparable to Microsoft’s Virtual Studio. But it can also fully meet the development needs of Python.

Let’s talk about the efficiency of Python. Python supports multi-process, multi-thread and coroutine (one level smaller than thread), and the program concurrency is higher than that of Shell. Python's core modules are basically implemented in C, so they are more efficient. If necessary, the Python modules that need to be implemented in Python may be rewritten in C to improve efficiency. Of course, you can also directly use C Python, a Python interpreter that is directly implemented entirely in C.
