Creating and Using Modules

1. Creating and Using Modules Sec 9-6 Web Design

2. Objectives The student will: • Know how to create and save a module in Python • Know how to include your modules in IDLE.

3. Modules • Once you start to create functions for Python you may want to store these functions and use them later in different program. • The files in which you stores functions is called a module • Modules are stored in files with an extension of .py (e.g. testrobots.py)

4. Creating a Module • Start Python. • From the File menu Select New Window • Type in the functions • It’s always a good idea to comment the code so you can remember what the module and the functions do • Save the file with a .py extension • Save the file in the same folder as your start IDLE program

5. Including Modules in IDLE Once you save your program you “include” it in your IDLE window: • fromtestrobotsimport * • Now all the functions are available for use… • Note that the lines not included in a function are executed immediately

6. Using Functions form a Module Once you have imported the functions you can simply call them:

7. Summary • Putting functions into modules helps keep things organized. • Include the functions in your program by: from module import * • Once imported all functions can be used.

8. Rest of Today • Complete the program from Monday. Show me the results when complete. • Everyone must do this!
