Study Notes
Python Basics
- The
max()function returns the maximum value in a list. - To create a list, you can use
list1 = [],list1 = list(), orlist1 = list([1, 2, 3]). - A set is a data type that does not allow duplicate values and is unordered.
- To create an empty set, use
set().
Classes and Objects
- A class is used to create an object.
- An object represents an entity in the real world with its identity and behavior.
- A class has an
__init__method, which is a constructor that initializes the object. - The
__init__method can have default arguments. - The
delkeyword is used to delete an object.
Inheritance
- Inheritance is a concept in object-oriented programming where a class can inherit properties and behavior from another class.
- The
class B(A):syntax is used for inheritance, whereBis the subclass andAis the superclass. - Multiple inheritance is when a class inherits from multiple classes.
Conditions and Loops
- If statements are used for conditional execution.
- The
elifkeyword is used to add an alternative condition to an if statement. - If statements can be used with logical operators (
and,or,not) to check multiple conditions.
Functions
- A function is a block of code that can be called multiple times from different parts of the program.
- The
type()function is used to determine the class of an object. - A method is a function inside a class.
Program Output
- The output of a program depends on the execution of the code.
- Conditional statements and functions can affect the output of a program.
- The output of a program can be a string, a number, or an error message.
