Basic Translation¶
Installing Gettext¶
import gettext
# Install translation - O(n)
gettext.install('myapp')
# Now use _() for translatable strings
message = _("Hello, World!")
Loading Translation Files¶
import gettext
# Load specific translation - O(n)
es = gettext.translation(
'myapp', # domain
localedir='locale',
languages=['es']
)
es.install()
# Translated strings use _()
print(_("Hello")) # Hola
