SUMMARY Python 3 is a loosely typed programming language that is designed to encourage easily read code. Python 3 comes with a simple Integrated Development Environment called IDLE. There are many other IDEs available, such as Thonny and Wing IDE 101, both of which are specifically designed for students.
LE
There are three main styles of programming in Python 3: •
interactive mode: quick tests and trials that can be programmed in the Python shell
•
script mode: text-based scripts that can be saved so that your applications can be reused
•
GUI applications: full, visually rich applications that can be produced in script mode.
As well as the basic programming commands available in Python, there is a large library of specialist modules that come with Python and can be imported into your programs such as the turtle and tkinter modules.
