In this section, you will write your Python commands in a text file instead of typing them into the Python shell. You’ll need a good text editor for that. If you’re on Windows, the default text editor is Notepad, a terrible editor. Instead, I recommend Notepad++. If you’re on Linux or OS X, whatever the default is will probably be fine.
Open your text editor and type the line
print("hello world"), like
Then save the file as
On Windows, I recommend that you save the file in “Computer” → “Local
Disk (C:)” → “Users” → [your user name] → create a new folder
called “programs”. So the location of the file will be
Now open the command line and use
cd to navigate to the directory
where you saved your program. If you’re on Windows and you followed my
advice above, you can open a new command prompt and type
Once you’re there, you can run your program with
$ python hello.py hello world
You did it! Try making changes to the text file and re-running the program (don’t forget to save the text file each time).
