Day 1:

· Programming lets you do more

· How to run your code

· Create a new program file

· Prepare  and run your code

· A program is more than a list of

     commands

· Your program is like a network of roads

· Branches are code intersections

· If/else branches

· The Python code needs

       interconnecting paths

·  Python uses indents to connect paths

· Loops let you run the same piece of code over 

   and over again

· Python’s while loop

· Your new gig at Starbuzz Coffee

· Here's the current Starbuzz code

· The cost is embedded in the HTML

· A string is a series of characters

· Find characters inside the text

· But how do you get at more than one character?

· The String Exposed

· Beans'R'Us is rewarding loyal customers

· Searching is complex

· Python data is smart

· Strings and numbers are different

· The program has overloaded the Beans'R'Us Server

· Time... if only you had more of it

· You're already using library code

· Order is restored

Day 3:

• Who won the surfing contest? 
• Associate the name with the score 
• Associate a key with a value using a hash 
• Iterate hash data with for 
• The data isn't sorted 
• When data gets complex 
• Return a data structure from a function 
• The code remains the same; it's the function that changes 
• TVN's data is on the money! 
• Head First Health Club is upgrading some systems 
• The program needs to create a transaction file 
• Use strings to format strings 
• The Format String Exposed 
• A late night email ruins your day 
• $50,000... for a donut?! 
• Only the sales from your program were rejected 
• The new bank uses a new format 
• Your coffee bar program still uses the old format 
• Don't just update your copy 
• So how do you create a module...? 
• The transaction file is working great, too 
• The health club has a new requirement 
• The Starbuzz code 
• The two discount functions have the same name 
• Fully Qualified Names (FQNs) prevent your programs from getting confused 

Day 5:

· What's that smell?

· Someone changed the file permissions

· When it couldn't write to the file, the program

  threw an exception

· Catch the exception

· Watch for exceptions with try/except

· There's an issue with the exception handler

· A message box demands attention

· Creating message boxes in Python

· Time to mix it up

· The music just kept on playing...

· Not all events are generated by button clicks

· Capturing the protocol event isn't enough

· Two buttons, or not two buttons? That is the 

   question...

· The checkbox is an on/off, flip/flop toggle

· Working with checkboxes in tkinter

· Model a slider on a scale

· Use pygame to set the volume

· Use tkinter for everything else

· The DJ wants to play more than one track

· Create code for each track as a function

· The new function contains other functions

· Your new function needs to create widgets and 

  event handlers

· The DJ is confused

· Group widgets together

· A frame widget contains other widgets

· A class is a machine for creating objects

· A class has methods that define behavior

· But how does an object call a method?

· The SoundPanel class looks a lot like the

            create gui() function

· class = methods + data

· The Class Exposed

· The DJ has an entire directory of tracks

Day 2:

· Starbuzz is out of beans!

· What does the new program need to do?

· Don't duplicate your code...

· ...Reuse your code instead

· Reuse code with functions

· Always get things in the right order

· Return data with the return command

· Use the Web, Luke

· The function always sends the same message

· Use parameters to avoid duplicating functions

· Someone decided to mess with your code

· The rest of the program can't see the password 

   variable

· When you call a function, the computer creates a 

   fresh list of variables

· When you leave a function, its variables get 

   thrown away

· Starbuzz is fully stocked!

· Surf's up in Codeville

· Find the highest score in the results file

· Iterate through the file with the open, for, close 

  pattern

· The file contains more than numbers...

· Split each line as you read it

· The split() method cuts the string

· But you need more than one top score

· Keeping track of 3 scores makes the code more

   complex

· An ordered list makes code much simpler

· Sorting is easier in memory

· You can't use a separate variable for each line of data

· An array lets you manage a whole train of data

·  Python gives you arrays with lists

· Sort the array before displaying the results

· Sort the scores from highest to lowest

Day 4:

• Head First TVN now produces game shows
• pygame is cross platform
• pygame Exposed
• 0... 2... 1... 9... blast off!
• tkinter gives you the event loop for free
• tkinter is packed with options
• The GUI works, but doesn't do anything
• Connect code to your button events
• The GUI program's now ready for a screentest
• But TVN is still not happy
• Label it
• Head-Ex needs a new delivery system
• They've already designed the interface
• Read data from the GUI
• The Entry and Text widgets let you enter text data into your GUI
• Read and write data to text fields
• Large Text fields are harder to handle
• One of the Head-Ex deliveries went astray
• Users can enter anything in the fields
• Radio buttons force users to choose a valid depot
• Creating radio buttons in tkinter
• The radio buttons should work together
• The radio buttons can share a model
• The system tells the other widgets when the model changes
• So how do you use models in tkinter?
• Head-Ex's business is expanding
• There are too many depots on the GUI
• An OptionMenu lets you have as many options as needed
• The model stays the same
• Things are going great at Head-Ex
