Is there something like f-strings in Kotlin?

Question

Is there a brief way in Kotlin to build formatted strings with variables, similar to f-strings in Python? For example:

f'My cat is {weight:.1f} pounds.'

Which would yield:

My cat is 25.3 pounds.

Answer 1

The usual way to do this is with String.format().

It's also an extension method on String, so you can call it as follows:

"My cat is %.1f pounds.".format(weight)

For details, see this question; the docs for the format patterns are here. (Both are for the Java version, but it's the same in Kotlin.)
