As an example, print a public IP Network. in order to execute code to display the public IP, We first need to complete the password verification process. Once the password is verified we will be able to see our public IP displayed in the terminal window. in order to suc

IPython is a Python-based Shell. with the support of the Python programming language, IPython is more powerful than the general Shell. next, let's take a look at the tutorial of installing the Python interactive interpreter IPython in Linux. IPython is the Python

What is an "interactive Python interpreter"?When you see the ">>>" symbol, it means you go into the interactive Python interpreter, also known as a "prompt."Note: Python is different from other computer languages, each line ends with a semicolon, and a line of

The interactive command line for Python can be configured through a startup file. When Python starts, it looks for the environment variable Pythonstartup and executes the program code in the file specified in the variable. The specified file name and address can be arbitrary. Pressing the TAB key automatically complements the content and command history. This is

The Python interactive command line can be configured through the Startup File. When Python is started, it looks for the environment variable PYTHONSTARTUP and executes the program code in the specified file in the variable. The specified file name and address can be arbitrary. When you press the Tab key, the content and command history are automatically suppleme

The interactive command line for Python can be configured with a startup file. When Python starts, it looks for the environment variable Pythonstartup and executes the program code in the file specified in the variable. The specified file name and address can be arbitrary. When you press the TAB key, the full content and command history are automatically filled.

After the test, I started to study Python advanced programming. Those who have used zsh will surely be impressed with its automatic complementing function. Similar functions can be achieved through simple custom Python interactive command lines. The specific operations are as follows: Create the ". pythonstartup" file in the user directory and write the
