4. Built-in Types¶. The following sections describe the standard types that are built into the interpreter. The principal built-in types are numerics, sequences, mappings, classes, instances and exceptions.
The @classmethod form is a function decorator – see the description of function definitions in Function definitions for details.. It can be called either on the class (such as C.f()) or on an instance (such as C().f()).The instance is ignored except for its class. If a class method is called for a derived class, the derived class object is passed as the implied first argument.

The ASCIIfication of 3 is "\x33" not "\x03"!. That is what python does for str(3) but it would be totally wrong for bytes, as they should be considered arrays of binary data and not be abused as strings.. The most easy way to achieve what you want is bytes((3,)), which is better than bytes() because initializing a list is much more expensive, so never use lists when you can use tuples.
It's like JSON. but fast and small. MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON.
Code equivalence. The exact code used to implement f-strings is not specified. However, it is guaranteed that any embedded value that is converted to a string will use that value's __format__ method. This is the same mechanism that str.format() uses to convert values to strings.. For example, this code:
This page describes the API functions provided by the FFI library in detail. It's recommended to read through the introduction and the FFI tutorial first. Glossary. cdecl — An abstract C type declaration (a Lua string).; ctype — A C type object. This is a special kind of cdata returned by ffi.typeof().It serves as a cdata constructor when called. cdata — A C data object.
This guide describes how to use the protocol buffer language to structure your protocol buffer data, including .proto file syntax and how to generate data access classes from your .proto files. It covers the proto2 version of the protocol buffers language: for information on the newer proto3 syntax
The General Hash Function Algorithm library contains implementations for a series of commonly used additive and rotative string hashing algorithm in the Object Pascal, C and C++ programming languages
The first declaration of month is explicit about returning a Month and about not modifying the state of the Date object. The second version leaves the reader guessing and opens more possibilities for uncaught bugs. Example; bad. This loop is a restricted form of std::find:
