- Separate inline comments by two or more spaces from the statement.
- Start inline comments with a # and a single space, like block comments.
- Don’t use them to explain the obvious.
Is PEP8 mandatory?
Pep8 is a coding standard and Style Guide for readability and long-term maintainability. It’s not a requirement for your code to work, just a good coding practice you should follow. There are also some automated tools you can use to help make your source code pep8 and other linters. Here’s an example of one.

What is PEP8 in Python interview questions?
What is the use of PEP 8 in Python? PEP 8 is a style guide for Python code. This document provides the coding conventions for writing code in Python. The coding conventions are about indentation, formatting, tabs, maximum line length, imports organization, line spacing etc.
How memory is managed in Python explain Pep 8?
Memory allocation can be defined as allocating a block of space in the computer memory to a program. In Python memory allocation and deallocation method is automatic as the Python developers created a garbage collector for Python so that the user does not have to do manual garbage collection.
What does pep8 stand for?
Python Enhancement Proposal 8
Python Enhancement Proposal 8, or PEP 8, is a style guide for Python code. In 2001, Guido van Rossum, Barry Warsaw, and Nick Coghlan created PEP 8 to help Python programmers write consistent and readable code.
How do you write beautiful code in Python?
Let me give you some simple rules to follow.
- Rule 1 — Write your variable names, method names, and function names in lowercase, separated by an underscore.
- Rule 2 — Keep these variable names short and simple, these are characters of your story.
- Rule 3 — ALL CONSTANTS IN CAPS.
- Rule 4 — CamelCase ClassNames.
What is auto PEP8?
autopep8 automatically formats Python code to conform to the PEP 8 style guide. It uses the pycodestyle utility to determine what parts of the code needs to be formatted. autopep8 is capable of fixing most of the formatting issues that can be reported by pycodestyle.
What is the best Python formatter?
The most popular Python formatters are:
- Black.
- isort.
- autopep8.
- YAPF.

Is Python good for coding interviews?
Beyond theoretical data structures, Python has powerful and convenient functionality built into its standard data structure implementations. These data structures are incredibly useful in coding interviews because they give you lots of functionality by default and let you focus your time on other parts of the problem.
How do you optimize memory in Python?
- Utilize Pytorch DataLoader.
- Optimized data type.
- Avoid using global variables, instead utilize local objects.
- Use yield keyword.
- Built-in Optimizing methods of Python.
- Import Statement Overhead.
- Data chunk.
Why Python is not memory efficient?
It is a faster way of memory allocation. It is a slower way of memory allocation. Once static memory is allocated, neither its size can be changed, nor it can be re-used. Hence, less efficient.
Does PyCharm use PEP8?
Tracking PEP8 rules
So, as you can see, PyCharm supports PEP8 as the official Python style guide. If you explore the list of inspections ( Ctrl+Alt+S – Inspections), you will see that PyCharm launches the pep8.py tool on your code, and pinpoints the code style violations.
What is an idiom in Python?
Idiomatic Python is what you write when the only thing you’re struggling with is the right way to solve your problem, and you’re not struggling with the programming language or some weird library error or a nasty data retrieval issue or something else extraneous to your real problem.
What is a Linter Python?
What are Linters? Linters are programs that advise about code quality by displaying warnings and errors. They can detect your Python code mistakes, notice invalid code patterns and find elements that do not follow your conventions.
What is Black Python?
Black is the uncompromising Python code formatter. By using it, you agree to cede control over minutiae of hand-formatting. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. You will save time and mental energy for more important matters.

Patterns for writing clean code in Python
- Use long descriptive names that are easy to read.
- Use descriptive intention revealing names.
- Avoid using ambiguous shorthand.
- Always use the same vocabulary.
- Don’t use magic numbers.
- Be consistent with your function naming convention.

Is Google written in Python?
Yes, Google has been a long-time supporter and user of the Python programming language, which is one of the official server-side languages at the company, in addition to C++, Java, and Go. Google has backed Python from almost the very beginning.
Why are coding interviews so hard?
Lack of data structures and algorithms knowledge
The first reason why a lot of people find coding interviews hard is because they lack the fundamental knowledge in data structures and algorithms.
Does Python use a lot of RAM?
Those numbers can easily fit in a 64-bit integer, so one would hope Python would store those million integers in no more than ~8MB: a million 8-byte objects. In fact, Python uses more like 35MB of RAM to store these numbers.
How much RAM can Python use?
Those numbers can easily fit in a 64-bit integer, so one would hope Python would store those million integers in no more than ~8MB: a million 8-byte objects. In fact, Python uses more like 35MB of RAM to store these numbers. Why? Because Python integers are objects, and objects have a lot of memory overhead.
