Been using python for almost 10 years. I never use any of the funky strings. Instead of reading like 10 PEPs for f strings, I just use the + operator on strings and backslash escaping, big whoop.

Right, because x + " " + y is more clear than of simply f"{x} {y}". Been using python for longer than 10 years and immediately started using f-strings when I could. It takes almost no time to understand the basics.

  Personally I do find the first version clearer, because it is based on general language rules.

    Especially if you come from other languages. a + " " + b will be clearer to devs that aren't senior python developers. the f string thing is just a marginal improvement at the cost of alienating other devs. But it's great for gatekeeping and job security.

age = 32 print(f"Age: {age}") Thus concludes the lecture on f-strings.

  I find it funny and satisfying that Python has converged to it's own "printf", by which I mean print(f"").
- layer8 3mo ago
  It’s unclear what the big advantage is over `print("Age: "+age)`. It’s even more characters, in that specific example.
  - kstrauser 3mo ago
    If age is a number, that won’t work.
    - layer8 3mo ago
      Admittedly I’m not so familiar with Python; it does work in Java. In that case, introducing a less hazardous string concatenation operator would seem more universally useful.
      - kstrauser 3mo ago
        In Python, that less hazardous string concatenation operator is an f-string.
        layer8 3mo ago
        I’m assuming you can only use it with string literals, hence it is less universally useful.
        TZubiri 3mo ago
        Nope, you can put expressions in them: f'{a} = {functionThatReturnsAButHasSideEffects()}'

Instead of 10 PEPs, you could read one helpful cheatsheet: https://www.pythonmorsels.com/string-formatting/#cheat-sheets https://www.pythonmorsels.com/string-formatting/#cheat-sheet....
- TZubiri 3mo ago
  Doesn't cover: - the trailing slash detail detailed in the OP - raw strings at all - more complex stuff like raw format strings Also, my mind is a temple, I don't learn python from cheatsheets from random secondary sources.
