Study Notes
Basic String Operations
- Concatenation combines two strings using the
+operator, e.g.,result = string1 + " " + string2produces "Hello World". - The
str()function converts non-string types to strings, useful for concatenation, e.g.,message = "I am " + str(age) + " years old.".
Input, Processing, and Output
- Programs follow a three-step process: receive input, process it, and produce output.
- Input can be any data during program execution, e.g.,
name = input("Enter your name: ").
Functions and Parameters
- Arguments are pieces of data sent to functions, allowing for customized processing.
- A parameter is a variable assigned the value of an argument when the function is called, defining the function's scope.
Reading Input
- The
input()function reads data as a string, even numeric inputs, e.g.,variable = input(prompt). - Numeric conversions require built-in functions like
int(item)andfloat(item)to ensure the item is valid.
Passing Multiple Arguments
- Functions can accept multiple arguments specified in a parameter list, separated by commas.
- Arguments can be passed by position, matching the order of parameters.
Printing Output
- The
print()function displays output, executing statements in the order they appear. - Multiple items in
print()are separated by spaces by default but can be customized using thesepargument.
Customizing Print Behavior
- Use the
endargument inprint()to change the default newline character to a specified delimiter, e.g.,print("Hello", end="#").
F-Strings
- Introduced in Python 3.6, f-strings allow inline variable interpolation for flexibility, e.g.,
greeting = f'Hello, {name}!'. - They support any valid Python expression within curly braces for dynamic string generation.
Error Handling
- A syntax error in code often requires correction in the indicated line to ensure proper execution.
Engagement and Participation
- Active tutorial participation can yield bonus marks, rewarding students with consistent attendance.
- Make-up sessions require email approval with valid reasons and are subject to attendance tracking.
Basic Coding Exercises
- Exercises include writing pseudo code for game logic and flowcharts for processes.
- Basic coding involves defining data types and user input operations related to game dynamics.
