Word scramble
Unscramble the letters and write each key term on the line.
1
AT.KLLEO(BROT, XTET='...')
Creates a tkinter label that shows text in the window. Use .config(text=...) to change what it shows, such as displaying a result. Options like font and fg set style.
2
REYTN = KT.OYETO(TRNR)
Creates a text box in the window. Call entry.get() to read what the user typed. It is always a string, so convert it with int() or float() to use it as a number.
3
RRVIATGSN()
A tkinter variable that stores the user's pick from a choice control (Checkbutton, Radiobutton or Combobox). Link it with variable= and read the choice with .get().
4
IXEFWGONOS.SOBESAHM()
Pops up a message window to tell the user a result. Its partner messagebox.showerror() pops up an error, such as when a handler finds invalid input. Both need a title and a message.
5
NITCRATASBO
Modelling only the attributes and methods that matter for a purpose and hiding the rest of the detail, such as a Student class that keeps just the data a school app needs.
6
AAUETNICOPLSN
Bundling an object's data and methods together and restricting access, so private data is only changed through public methods that can check values are valid.
7
FDE EEA_TSE(LFSG, GEA):
A setter method that checks a new value (such as a valid age range) before storing it in a private attribute, rejecting or reporting bad values so the object never holds invalid data.
8
LORSIEGTIAANNE
Finding the attributes and methods that several classes share and moving them into one more general parent class, so the code is not repeated in each specialised class.
