This part of ISO 639 provides a code consisting of language code elements comprising two-letter lan­guage identifiers for the representation of names of languages. The language identifiers according to this part of ISO 639 were devised originally for use in ter­minology, lexicography and linguistics, but may be adopted for any application requiring the expression of language in two-letter A list containing three-letter codes would be a separate project. The major international commercial languages generally have two-letter codes, so I actually did not encounter many cases like Hawaiian. There are some ISO 639-1 codes which don't appear in the list below. For example, ISO 639-1 has codes for Latin, Esperanto, Manx, Fulah, and Nauru. ISO 639 has five code lists. ISO 639 is a standardized nomenclature used to classify all known languages. Each language is assigned a 2-letter (639-1) and 3-letter (639-2 and 639-3), lowercase abbreviation, amended in later versions of the nomenclature. The system is highly useful for linguists and ethnographers to categorize the languages ISO 639-1, ISO 639-2, ISO 639-3 and ISO 639-5 parts are all supported. Installing iso639-lang and Supported Versions. iso639-lang is available on PyPI: $ pip install iso639-lang iso639-lang supports Python 3.7+. Usage.

Paul; Simons, Gary F.; Fennig, Charles D., eds. (2016). Two-letter code space. Two-letter (formerly "Alpha-2") identifiers (for codes composed of 2 letters of the ISO basic Latin alphabet) are used in Set 1. When codes for a wider range of languages were desired, more than 2 letter combinations could cover (a maximum of 26 2 = 676), Set 2 was developed using three-letter codes. (However, the latter The ISO codes refer primarily to spoken languages. e.g., Sanskrit only has the code sa despite the many different writing systems used for it. That's why there's also a ISO 639 code yue for Cantonese and hak for Hakka. Even zh-TW and zh-CN technically don't refer to traditional and simplified, just zh as spoken in TW or CN. ISO 3166-2:CL is the entry for Chile in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. Currently for Chile, ISO 3166-2 codes are defined for 16 regions. xtoy.
