Download python3, run python code in a terminal window and a simple text editor. The simplest code such as: printt("Hello python world")
1. Run in the python terminal window
In a command window, the cd command can navigate the file system, and the dir command can list all files in the current directory. Since I downloaded python to the E drive, hold down the shift key on the E drive and right-click the mouse to select "Open command window here". (Enter python in the terminal window and press Enter. If the python prompt >>> appears, it means that python is installed on your system.)
Second, the text editor to run the python program
First of all, build a python programming environment in different operating systems, mainly in LINUX, OS C, Windows system to build a python programming environment, I use Windows system, and then I may use LINUX system (mainly a matter of time, did not find redhat linux 9.0 .iso file). When running python in a terminal session, a command window is opened and a python terminal session is started. Similar to one, to close the terminal session, press Ctrl+Z, then press Enter or execute the command exit().
Install a text editor, Geany is recommended, you can visit http:\\geany.org\, click Releases under Download, find and install a file similar to geany-1.33_setup.exe. Next, create a folder for storing the project and name it python_work, create a new file hello_world.py in Geany and save it to python_work. Enter the following line of code in it: print("Hello python world!"), then press the icon of the two gears to run the program:
Most programs can be run from the editor, but when the problem to be solved is more complex, the program written may need to be run from the terminal.
