Introduction ¶ Warning Most of this object should only be useful if you actually manipulate i18n stuff from Python. If you are a regular add-on, you should only bother about contexts member, and the register() / unregister() functions! The pgettext() family of functions should only be used in rare, specific cases (like e.g. complex “composited” UI strings…). To add translations to your Python script, you must define a dictionary formatted like that: {locale: {msg_key: msg_translation, ...}, ...} where: locale is either a lang ISO code (e.g. fr ), a lang+country code (e.g. pt_BR ), a lang+variant code (e.g. sr&#64;latin ), or a full code (e.g. uz_UZ&#64;cyrilic ). msg_key is a tuple (context, org message) - use, as much as possible, the predefined contexts . msg_translation is the translated message in given language! Then, call bpy.app.translations.register(__name__, your_dict) in your register() function, and bpy.app.translations.unregister(__name__) in your unregister() one. The Manage UI translations add-on has several functions to help you collect strings to translate, and generate the needed Python code (the translation dictionary), as well as optional intermediary po files if you want some… See How to Translate Blender and Using i18n in Blender Code for more info.
