<!-- Answer -->
To use `pybabel` in the Apache Superset codebase, you can follow these steps:
1. **Extract Translations**: Use `pybabel extract` to extract translatable
strings from the codebase. This command generates a `.pot` file containing all
the strings that need translation.
```sh
pybabel extract -F superset/translations/babel.cfg -o
superset/translations/messages.pot --no-location --sort-output
--copyright-holder=Superset --project=Superset -k _ -k __ -k t -k tn:1,2 -k tct
.
```
2. **Update Translations**: Use `pybabel update` to update the `.po` files
with the new messages from the `.pot` file.
```sh
pybabel update -i superset/translations/messages.pot -d
superset/translations --ignore-obsolete
```
3. **Compile Translations**: After translating the `.po` files, compile them
into binary `.mo` files.
```sh
pybabel compile -d superset/translations
```
4. **Initialize New Language**: If you want to add a new language, use the
`pybabel init` command with the appropriate language code.
```sh
pybabel init -i superset/translations/messages.pot -d
superset/translations -l LANGUAGE_CODE
```
These steps are part of the process to manage translations in Superset using
`pybabel`. The `babel_update.sh` script in the Superset repository automates
many of these steps
