Study Notes
Introduction to Python
- Python is a versatile programming language used for software development, automation, data analysis, game creation, scientific calculations, and artificial intelligence.
- It offers a vast collection of libraries and frameworks, simplifying various tasks.
- Known for its simplicity and readability, Python is suitable for both beginners and experienced developers.
Getting Started with Python
- Access Python through Inspire Campus with three steps: download Python, start IDLE, and open Command Prompt.
- IDLE (Integrated Development and Learning Environment) is the IDE bundled with Python, designed for ease of use.
IDLE Features
- IDLE consists of two windows: Shell and Editor.
- Shell Window: Executes and displays code instantly, but does not allow saving or editing once ENTER is pressed.
- Editor Window: Allows code saving and editing, must be saved before execution.
- Code syntax highlighting aids in reading and debugging by color-coding different parts of the code.
Debugging
- Errors are indicated by unresponsive code or red text highlights, signaling the need for code debugging.
The Print Function
- The print() function outputs information to the console or terminal, accepting one or more arguments.
- Example usage:
print("Your message")displays "Your message."
- Example usage:
Arithmetic Operators
- Python functions as a basic calculator using operators for arithmetic tasks:
- Addition:
print(2+2) - Subtraction:
print(2-1) - Division:
print(2/2) - Multiplication:
print(2*2) - Exponentiation:
print(2**2)
- Addition:
Strings in Python
- Strings are sequences of characters enclosed in single (' ') or double (" ") quotes.
- Strings can be combined using commas in the print function:
- Example:
print("My name is John", "I can code")yields "My name is John I can code."
- Example:
Practical Coding Guidelines
- When using the print function, include brackets after print and use inverted commas for text.
- For mathematical strings, no inverted commas are used, and calculations are performed directly in print.
Independent Activity Instructions
- Create and save a new folder in IDLE for "Python Game Coding Lesson 1."
- Develop a code that welcomes users and demonstrates the use of the print function with various mathematical expressions.
- Utilize operators to display results of arithmetic calculations, including multiplication, addition, subtraction, division, and exponentiation.
Flowcharts
- Flowcharts visually represent algorithms and are read from top to bottom.
- They use distinct shapes and arrows to indicate the sequence of commands.
- Programmers use flowcharts to efficiently plan and organize their code.
- Each command type is depicted with a specific shape.
Creating a Flowchart
- Choose a game title and sketch a flowchart by hand.
- Complete guided activities on Inspire Campus for deeper understanding.
Running Pygame
- Steps for creating a basic Pygame program include:
- Create a folder named "Lesson 2: Game title".
- Open IDLE and create a new file.
- Write the initial code to define how to draw on the screen, using the command to display the game title.
- Use
import pgzrunto prepare Pygame for execution. - Save, run the code, and observe the displayed title.
Variables
- Variables act as containers for information in Python, allowing users to store various data types.
- Important to follow variable naming rules when defining variables.
- Example of variable assignment includes characters or words, like
message="Hello".
Using Print with Variables
- To display the value of variables, use
printwith the variable name in brackets. - For example,
print(message)outputs "Hello". - Multiple variables can be printed together using a comma, such as
print(message, my_name).
Creating Characters (Actors)
- In game development, characters are referred to as "actors".
- Actors can perform actions or interact within the game environment.
Calculations with Variables
- Variables can store numerical values for calculations.
- Example:
x=3,y=x*2, changes and utilizes variable values effectively. - Variables can be updated throughout the code.
Lists
- Lists store multiple items in Python, starting with index 0.
- Items can be grouped in brackets and separated by commas, such as
animals=["cat", "dog"]. - Access list items by specifying the index in brackets.
Print Function
- The print function displays text or variable values enclosed in brackets and inverted commas.
- Understanding of how to create and use variables with the print function is key for outputting messages accurately.
Independent Activity: Number Fun Game
- Create a "Number fun" game using Python to assign various themes to numbers (0-5 or up to 10).
- Ideas include:
- Inspirational quotes associated with each number.
- Daily fortunes or colors linked to numbers.
- Guess the animal game, challenging players to match numbers with animals.
- Random surprises or mini-games connected to specific numbers.
- Class tests or quizzes assigning questions to numbers with corresponding scores.
Making Decisions in Games
- Game decisions often require computers to ask questions and compare values.
- Boolean values in Python can represent true or false conditions, aiding in decision-making.
- Boolean values must start with a capital letter and can be stored in variables.
Logical Operators
- Logical operators allow for comparisons:
-
and: Both conditions must be true. -
or: Only one condition needs to be true.
-
- Common keywords include:
-
if: Checks if a condition is true. -
elif: Checks additional conditions after anif. -
else: Executes code if all previous conditions are false.
-
Python Assignment and Comparison Operators
- The
=operator assigns a value to a variable (e.g.,score = 10). - The
==operator checks if two values are equal. - Comparison operators like
>,<, and==return True or False when comparing values.
Branching in Code
- Branching allows different actions based on conditions using
if,elif, andelse. - An
ifstatement initiates a decision pathway, needing a colon at the end. - An
if...elsestatement provides alternative actions based on the truthfulness of a condition.
Multiple Conditions
- Multiple conditions can be checked using logical operators:
- For
and, all conditions must be true for a True output. - For
or, at least one condition must be true for a True output.
- For
Practical Coding Examples
- Simple branching can be illustrated with an
ifstatement for checking a condition (e.g.,if door == "red":). - Using
if...elseenables the game to have a backup plan (e.g., check if treasure is found). - The
indexfunction retrieves the position of elements in a list or string, enhancing interactivity in games.
While Loops
- A
whileloop continues to execute as long as a condition remains true, initiating only if the condition holds (e.g.,while not have_sword:). - User input can control the loop's execution (e.g., questioning whether the player has a sword).
