PEP 8 E305 expected 2 blank lines after class or function definition found 1

PEP 8 is a style guide for Python code that provides guidelines on how to format and structure your code to enhance its readability. One of the guidelines mentioned in PEP 8 is to have two blank lines after a class or function definition.

Here is an example of a code snippet that violates this guideline:

def my_function():
    print("Hello, world!")

class MyClass:
    def __init__(self):
        self.my_variable = 42

In this example, there is only one blank line after the my_function definition, whereas PEP 8 recommends having two blank lines. To conform with PEP 8, you should modify the code to add an additional blank line after the function definition:

def my_function():
    print("Hello, world!")


class MyClass:
    def __init__(self):
        self.my_variable = 42

By following the PEP 8 guidelines, you make your code more readable and consistent, which can make it easier for other developers to understand and maintain your code
