PEP 8 E302 - Python

PEP 8 is a style guide for Python code. One of the most commonly violated rules is E302, which states that there should be no blank lines following a function or class definition.

As a programmer, it is important to follow the PEP 8 guidelines when writing Python code because it makes your code more readable and consistent. This can also make it easier for others to understand and maintain your code.

Here is an example of a violation of E302:

def my_function():
    
    # code goes here
    

In this example, there is a blank line following the function definition. To fix this violation, we should remove the blank line:

def my_function():
    # code goes here

It is important to note that E302 only applies to function and class definitions, and not any other type of block. For example, it is perfectly acceptable to have a blank line between two if statements.

If you are unsure whether your code is following the PEP 8 guidelines, there are several tools available to help you. One popular tool is Flake8, which scans your code and reports any violations of the PEP 8 guidelines.

In conclusion, following the PEP 8 guidelines, and specifically E302, can improve the readability and consistency of your Python code. By doing so, you can make it easier for yourself and others to understand and maintain your code.
