They support a wide range of programming activities including mathematics, graphical user interfaces (GUI), file operations, image manipulation, turtle graphics and games.
The question is how do you discover the functionality provided by a particular module?
Here's a step-by-step process to explore any Python module.
Step 1: Start an Interactive Mode Session
Boot up your Raspberry Pi and begin a Interactive Mode session in a new terminal window.
Step 2: Import a Module
To work with a module you'll need to import it first. Type åin the following statement next to the '
Step 3: Use dir()
Now type in the following statement next to the '
What you'll see is a list of the names (which includes variables and functions) defined by the '
Step 4: Use help()
Next try this statement:
Now you can see the all the 'platform' module manual pages. Press the '

Next try this statement:
>>> help(platform)
