Agreed. There are things that languages must get right at the very beginning or be plagued by inconveniences forever. This is one of them. I got a number of bugs and test failures because I forgot an f before a string with interpolated values. Python is rooted in the 80s. Maybe Guido didn't get the idea because maybe his background was only with languages without interpolation. Example: C has argument replacement with printf("%d", 42) and no interpolation.

I think I would keep the f-prefix if I were to do a Python dialect from scratch with lessons learned. Making { a special character in any string seems excessive and prone to user injected rogue values that are hard to catch in all places of a large system. Having the slightly safer types of strings be the default seems prudent.

It's interesting to note that the creator of C and his well known friend also created m4 in the 70's, and it's very similar to "string interpolation", maybe even taken to the extreme. I was actually program-wise "raised" by The C Programming Language in the early 90's, and I only found out about m4 a month ago.
