PEP8: стандарт оформления кода Python

PEP 8 (Python Enhancement Proposal 8)

PEP 8 is a coding style guide for the Python programming language. Created by Guido van Rossum, the primary developer of Python, PEP 8 defines rules and recommendations for the visual layout of code, including naming conventions, formatting, indentation, comments, and other aspects of writing clean and readable code.

Adhering to the PEP 8 coding style not only improves the readability and understandability of code, but also reduces the number of errors and makes software maintenance easier. Following PEP 8 helps your code to be consistent, understandable, and suitable for collaborative work with other developers.

Code Examples that follow PEP 8:

1. Variable and function naming:

def calculate_average(numbers_list):
    total_sum = sum(numbers_list)
    average = total_sum / len(numbers_list)
    return average

2. Formatting of operators:

if x > 5 and y < 10:
    print("x is greater than 5 and y is less than 10")

3. Indentation:

def print_numbers():
    for i in range(10):
        print(i)

4. Comments:

# This function adds two numbers
def add_numbers(a, b):
    return a + b

5. Line length:

if x > 5 and y < 10 and z == 20 and x != y and a > b and b < c:
    print("Complicated condition")

6. Blank lines:

def calculate_average(numbers_list):
    
    total_sum = sum(numbers_list)
    average = total_sum / len(numbers_list)
    
    return average

7. Module and package naming:

my_module.py or my_package

These are just some examples of applying the PEP 8 standards to your code. Following these recommendations will help you write code that is easier to read, understand, and maintain. PEP 8 is also important for maintaining consistency and style conformity, which is particularly important when working in a team of developers. It is always recommended to check your code against the PEP 8 standards to ensure that your code follows the best practices of Python programming.
