OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
![### Class: Keyboard
A `Keyboard` class is being defined, which takes in a list of buttons and maintains a dictionary with positions as keys and Button objects as values.
#### Code Implementation
```python
class Keyboard:
"""A Keyboard takes in a list of buttons, and has a dictionary of positions as keys, and Buttons as values."""
# Example of how to create buttons and a keyboard
>>> b1 = Button("button1", "H")
>>> b2 = Button("button2", "I")
>>> k = Keyboard([b1, b2])
# Ensure the button is added to the dictionary
>>> "button1" in k.buttons.keys()
True
# Accessing properties of the button
>>> k.buttons["button1"].letter
'H'
>>> k.buttons["button1"].name
'button1'
# Pressing a button and returning the letter
>>> k.press("button1")
'H'
# Trying to press a non-existent button
>>> k.press("button100")
''
# Checking if a button was pressed
>>> b1.pressed
0
>>> b2.pressed
0
# Simulating typing by pressing a series of buttons
>>> k.typing(["button1", "button2"])
'HI'
>>> k.typing(["button2", "button1"])
'IH'
# Ensure typing calls press
>>> b1.pressed
3
>>> b2.pressed
