F-strings

F-strings are a readable approach to building new strings from existing strings & variables.

from employees
select full_name = f"{first_name} {last_name}"

This can be much easier to read for longer strings, relative to the SQL approach:

from web
select url = f"http{tls}://www.{domain}.{tld}/{page}"

Note that currently interpolations can only contain plain variable names and not whole expressions like Python, so this won't work:

from tracks
select length_str = f"{length_seconds / 60} minutes"

Roadmap

In the future, f-strings may incorporate string formatting such as datetimes, numbers, and padding. If there's a feature that would be helpful, please post an issue.
