1. Consistency
Reason: Consistent code is easier to read and understand. PEP 8 provides a standard style guide that promotes consistency across different projects and among different developers.
2. Readability
Reason: Readable code is easier to understand and debug. PEP 8 encourages practices that make your code more readable.
Step 1: Understanding Attributes
In Python, a class can have attributes (variables) that store information. For example, a Person class might have attributes for name and age.
Step 2: Introducing Private Attributes
To protect the attributes and ensure they are not changed directly, we make them private by prefixing them with an underscore _. This is a convention in Python to indicate that these attributes should not be accessed directly.
SyntaxError: invalid syntax
This usually means there's a typo or a mistake in the code structure. Check for missing colons, parentheses, or indentation errors.
NameError: name 'variable' is not defined
This occurs when you try to use a variable or function before it's declared. Ensure that all variables and functions are defined before use.
