I think honestly it is you who misread my comment... I was saying the id() issue isn't a real problem, the weirdness around "wtf!" not being equal to itself und

  But "is" doesn't check equality. It checks reference equality. Maybe the real wtf here is they made that check a temptingly short infix operator rather than a function named reference_equals().

  "wtf!" is consistently equal to itself in Python. The fact that you could have separate string objects both representing that text, is entirely orthogonal to that.

  `is` is more like doing this in C: char* s1 = "wtf!"; char* s2 = "wtf!"; if (s1 == s2) { ... } They may or may not be stored in the same place depending on your compiler (clang and gcc yes, msvc no, at least with just a quick default build). If you actually want to do an equality check, you need to use `==` (in Python) which would be like using `strcmp` in C. > "wtf!" not being equal to itself It is equal to itself, but multiple variables referencing that string may not hold references to the same (literal, in memory) string.
