They may propose an implementation, ... them. Examples include procedures, guidelines, changes to the decision-making process, and changes to the tools or environment used in Python development....

Design exception hierarchies based on the distinctions that code catching the exceptions is likely to need, rather than the locations where the exceptions are raised. Aim to answer the question “What went wrong?” programmatically, rather than only stating that “A problem occurred” (see PEP 3151 for an example of this lesson being learned for the builtin exception hierarchy)

January 12, 2025 - Therefore, PEP 8 also outlines ways to allow statements to run over several lines. Python will assume line continuation if code is contained within parentheses, brackets, or braces: ... In this example, you moved arg_three and arg_four onto a new line, indented at the same level as the first ...

This PEP contains the index of all Python Enhancement Proposals, known as PEPs. PEP numbers are assigned by the PEP editors, and once assigned are never changed. The version control history of the PEP texts represent their historical record.

February 18, 2019 - A new mailing list was also created for discussing the design of Python 3. However, when creating the new mailing list, instead of typing “py3k” as he had intended, Guido accidentally transposed the middle two characters, so the actual name of the mailing list became “p3yk”. Rather than going back and fixing the typo, it was decided that this would be the official name of the project. (Humor has always been an important influence within the Python community, especially considering that the language was named after a British comedy troupe.) In the following sections, I’ll discuss each of the four PEPs that I submitted during this period.

February 13, 2026 - Stay informed: read the PEPs associated with new Python versions to understand the language's evolution. ... # Example of code following multiple PEPs at once from dataclasses import dataclass # PEP 557 @dataclass # PEP 557 - Data Classes class Student: """Represents a student enrolled in a course.""" # PEP 257 name: str # PEP 484 - Type Hints age: int # PEP 484 average: float # PEP 484 def is_passing(self) -> bool: # PEP 484 + PEP 8 (snake_case) """Check if the student is passing (average >= 10).""" # PEP 257 return self.average >= 10.0 # PEP 8: two blank lines before module-level definitions

August 13, 2000 - This PEP contains the index of all Python Enhancement Proposals, known as PEPs. PEP numbers are assigned by the PEP editors, and once assigned are never changed.

March 7, 2023 - PEPs are typically written in plain text or reStructuredText, and they follow a standard template that includes sections such as “Abstract,” “Motivation,” “Specification,” and “References.” · Python PEPs can be found on the Python website in the PEP Index, which provides a comprehensive list of all the PEPs that have been accepted, rejected, or are still under consideration.

For example: ===== ========================= col 1 col 2 ===== ========================= 1 Second column of row 1. 2 Second column of row 2. Second line of paragraph. 3 - Second column of row 3. - Second item in bullet list (row 3, column 2). ===== ========================= When referencing an external web page in the body of a PEP, you should include the title of the page or a suitable description in the text, with either an inline hyperlink or a separate explicit target with the URL.

The canonical form of PEP links are zero-padded, such as https://peps.python.org/pep-0008/. Shortcut redirects are also available. For example, https://peps.python.org/8 redirects to the canonical link.

November 24, 2020 - Capitalized_Words_With_Underscores In addition to these few leading or trailing underscores are also considered. Examples: single_leading_underscore: weak "internal use" indicator. E.g. from M import * does not import objects whose name starts with an underscore. single_trailing_underscore_: used to avoid conflicts with Python keyword.

June 4, 2024 - Informational PEPs: These PEPs provide information to the Python community. They do not propose changes to Python or its processes. Examples include PEP 8 and PEP 20.

February 6, 2025 - For example, below is the Turtle serialization of the datatype property peps:type, which represents the type of the PEP (“Informational”, “Standard Track”, etc). It says that the property peps:type is a owl:DatatypeProperty with a domain of peps:PythonEnhancementProposal and a range of xsd:string, meaning that the property peps:type is a property on the class pep:PythonEnhancementProposal that has a value that is a string:
