Can I import Python's 3.6's formatted string literals (f-strings) into older 3.x, 2.x Python?

here's what I use:

text = "Foo is {age} {units} old".format(**locals())

it unpacks (**) the dict returned by locals() which has all your local variables as a dict {variable_name: value}

Note this will not work for variables declared in an outer scope, unless you import it to the local scope with nonlocal (Python 3.0+).

you can also use

text.format(**locals(),**globals())

to include global variables in your string.
