First I have to admit that I forgot space! But if we like to be
pedantic (what I am not sure) then we compare <space> vs <shift+( and
shif+)> so 1 vs 4 , right? So not two keystrokes but three?

I am totally on your side here! Just forgive me next:
print(f"{foo}, {bar}, {baz}") # 29 :P

I am not sure if links below could bring a little light to this, but
probably it could be interesting:
Julia has print and println functions but has also printf macro. About
motivation why not function you could read here ->
https://stackoverflow.com/questions/19783030/in-julia-why-is-printf-a-macro-instead-of-a-function#19784718
and update of view is IMHO worth to read too ->
