working with National Research Institute of Mathematics and
Science in Netherland.

Scriptmode
Click here to open a New File.

17. Python (a Computer Language)
Scriptmode
• This is a script window. We can write a
complete program here.
• Afterwards, we save the file as we have
saved the file with the name
MyFirstProgram.py here.
• Then in run menu, click on run module or
use F5 Key.

18. Python (a Computer Language)
Scriptmode
• As we click on run module or use F5, we
