PyCharm provides a dedicated intention action to wrap strings in Django templates in
{%trans%}, or {%blocktrans%} tags.
The lines with i18n tags are marked with 
icon in the gutter.
- Open the desired Django template for editing, and select strings to be marked for translation.
- Press Alt+Enter, or click the light bulb to reveal the list of available
intention actions:
- Select intention action Wrap with 'trans' tag, and press
Enter. PyCharm wraps selected text in translation tags, and adds
{%
load i18n%}, if extracting text is performed for the first time.
