Apply f-string interpolation to a string

Question

Is there a way to achieve applying f-strings interpolation dynamically on a string?

For example given the string a = '{len([1])}'

a.interpolate() to give '1'

Try this:

 a = f'{len([1])}'
 print(a)
 #1

This is the opposite of what OP wants – wjandrea Oct 04 '19 at 01:18
How is that the opposite? please explain – ExplodingGayFish Oct 04 '19 at 01:21
OP wants dynamic, but this is static. OP wants `a == '{len([1])}'`, but in your code `a == '1'` – wjandrea Oct 04 '19 at 01:23
