Running Python in Script Mode
1. Find your text editor
- Windows: "Start" -> "Accessories" -> "Notepad"
- Mac OS X: Open TextEdit, then go to the menubar and click "Format" -> "Make Plain Text"
- Linux: Run "gedit", "kedit", "mousepad", "nano", "vim", "emacs", or the like.
2. In your text editor, type the following (don't just copy and paste, that's lazy, typing reinforces the learning):
#!/usr/bin/python print "We are the knights who say, Ni!"
3. Save the file as "hello.py", under some obvious directory that you won't mind saving a lot of python files in.
4. Now, run it:
- Open up your command line/terminal again, change to the directory where you just saved your python file, and type:
5. Viola! Python printed "We are the knights who say, Ni!" to your screen! You now know how to create and execute python scripts.
- Modify the hello.py program to say hello to a historical political leader (or to Ada Lovelace).
- Change the program so that after the greeting, it demands, "You must cut down the mightiest tree in the forest with.... A HERRING!".
Running Scripts in Interactive Mode
If you want to run scripts in interactive mode, you can start python with "-i". This can be very useful for debugging and prototyping:
python -i hello.py
